The AugerPrime Radio Detector will significantly increase the sky coverage of mass-sensitive measurements of ultra-high energy cosmic rays with the Pierre Auger Observatory. The detection of highly inclined air showers with the world’s largest 3000 km2 radio-antenna array in coincidence with the Auger water-Cherenkov detector provides a clean separation of the electromagnetic and muonic shower components. The combination of these highly complementary measurements yields a strong sensitivity to the mass composition of cosmic rays. We will present the first results of an end-to-end simulation study of the performance of the AugerPrime Radio Detector. The study features a complete description of the AugerPrime radio antennas and reconstruction of the properties of inclined air showers, in particular the electromagnetic energy. The performance is evaluated utilizing a comprehensive set of simulated air showers together with recorded background. The estimation of an energy-and direction-dependent aperture yields an estimation of the expected 10-year event statistics. The potential to measure the number of muons in air showers with the achieved statistics is outlined. Based on the achieved energy resolution, the potential to discriminate between different cosmic-ray primaries is presented.

The Jiangmen Underground Neutrino Observatory (JUNO) is a large scale neutrino experiment with multiple physics goals including deter mining the neutrino mass hierarchy, the accurate measurement of neutrino oscillation parameters, the neutrino detection from the super nova, the Sun, and the Earth, etc. JUNO puts forward physically and technologically stringent requirements for its central detector (CD), including a large volume and target mass (20 kt liquid scintillator, LS), a high energy resolution (3% at 1 MeV), a high light transmittance, the largest possible photomultiplier (PMT) coverage, the lowest possible radioactive background, etc. The CD design, using a spherical acrylic vessel with a diameter of 35.4 m to contain the LS and a stainless steel structure to support the acrylic vessel and PMTs, was chosen and optimized. The acrylic vessel and the stainless steel structure will be immersed in pure water to shield the radioactive back ground and bear great buoyancy. The challenging requirements of the acrylic sphere have been achieved, such as a low intrinsic radioactivity and high transmittance of the manufactured acrylic panels, the tensile and compressive acrylic node design with embedded stainless steel pad, one-time polymerization for multiple bonding lines. Moreover, several technical challenges of the stainless steel structure have been solved: the production of low radioactivity stainless steel material, the deformation and precision control during production and assembly, the usage of high strength stainless steel rivet bolt and of high friction efficient linkage plate. Finally, the design of the ancillary equipment like the LS filling …

The energy spectrum of cosmic rays extends to beyond 100EeV. Where and how these particles, predominantly the nuclei of the common elements up to iron, are accelerated is one of the major puzzles of astroparticle physics. The flux above 50 EeV is about 0.5 particles per square kilometer per century, so that measuring their properties requires the detection of the cascades or air showers that the particles create in the atmosphere. In this paper, the methods used by the Pierre Auger Collaboration to obtain the arrival directions and energies of the 100 highest-energy particles in the range 78–166 EeV are outlined, and details of the main features of the air showers produced by the cosmic rays are presented. Phase I of operation of the observatory ended on 2020 December 31. It is thus timely to release a catalog to demonstrate the quality of the data that lie behind measurements of the energy spectrum, the …

We use the surface detector of the Pierre Auger Observatory to search for air showers initiated by photons with an energy above 1019 eV. Photons in the zenith angle range from 30◦ to 60◦ can be identified in the overwhelming background of showers initiated by charged cosmic rays through the broader time structure of the signals induced in the water-Cherenkov detectors of the array and the steeper lateral distribution of shower particles reaching ground. Applying the search method to data collected between January 2004 and June 2020, upper limits at 95% CL are set to an E− 2 diffuse flux of ultra-high energy photons above 1019 eV, 2× 1019 eV and 4× 1019 eV amounting to 2. 11× 10− 3, 3. 12× 10− 4 and 1. 72× 10− 4 km− 2 sr− 1 yr− 1, respectively. While the sensitivity of the present search around 2× 1019 eV approaches expectations of cosmogenic photon fluxes in the case of a pure-proton composition, it is …

The Surface Detector (SD) of the Pierre Auger Observatory comprises about 1600 water-Cherenkov detectors arranged in an 1.5 km triangular grid over an area of∼ 3000 km2. Extensive air-showers are measured by recording the signals and arrival times of the secondary particles at the ground level, which spread over areas larger than 15km2 for primary energies above 3EeV. The Cherenkov light produced by the shower particles in each WCD are collected by three 9-inch Photonis XP1805 photomultipliers (Large PMTs, LPMTs), for which each input is split in two channels, one amplified (High Gain) with a factor of 32 with respect to the other (Low Gain). Such gain ratio is required to achieve a dynamic range of measurement varying from very low signals generated by single atmospheric muons (used to calibrate the detector), to small signals produced by few shower particles reaching the stations far from the impact point of the shower core at the ground, up to hundreds of thousands of particles in the station closest to the core. When the distance between the detector and the shower core is shorter than a few hundred meters, the dynamic range turns out to be insufficient to record the signal produced by the huge amount of secondary particles hitting the WCD, which is then tagged as saturated. The saturation initially appears only in the digitized signal traces, as it is due to the FADCs overflow. An actual saturation of the photomultiplier is instead observed when extreme amounts of light reach the LPMTs photocathodes, resulting in a deviation from the linear response. A recovery procedure [1] was implemented to estimate the loss of signal due …

Thanks to the high-quality data from the Pierre Auger Observatory [1], the world’s largest cosmic ray observatory, significant progress has been made in the quest to find the origin of ultrahigh-energy cosmic rays (UHECRs). In particular, regarding the arrival direction studies, a dipolar modulation in RA at energies above 8EeV has been established with a significance above 5???? [2]. The direction of this dipole,∼ 115◦ away from the Galactic Center, suggests an extragalactic origin of cosmic rays above this energy threshold. Moreover, for lower energies, a change in the equatorial dipole amplitudes and phases has been observed [3]. But, given that the amplitudes are small, these results are not yet statistically significant. However, they are indicative of a transition in the origin of the anisotropies from a galactic one (with phases close to the Galactic Center) to an extragalactic one at energies above a few EeV.Magnetic deflections are proportional to ????/????, and cosmic rays have a reduced horizon at ultrahigh energies. Thus, we also search for small and intermediate-angular-scale anisotropies with the highest-energy events that could help to trace their sources. The Auger Collaboration has reported an excess in the Centaurus region, which has grown steadily since the beginning of the operation of the Observatory [4, 5]. Furthermore, an indication of anisotropy has been reported when searching for correlations with catalogs of potential sources. In particular, the most significant result is for the starburst catalog, which has two galaxies, NGC4945 and M83, in the Centaurus region and one, NGC253, in a region close to the Galactic South Pole, where a …

Cosmic-ray induced extensive air showers emit impulsive radio signals, which are observed by the Auger Engineering Radio Array (AERA)[3] in the frequency range of 30− 80MHz. Following the success of interferometry in radio astronomy, it is natural to wonder if interferometry can also be used in the radio observations of air showers. There have been several attempts to use radio interferometry for the observation and reconstruction of extensive air showers [4–6]. Recently, it was shown on simulations how interferometry can be used to reconstruct the air shower axis and depth of shower maximum (Xmax)[1] and the applicability to the auger radio detectors was investigated in [2]. In Figure 1, we summarise the steps involved in applying radio interferometry to air showers following this approach. For this method to work, individual detector stations need to be synchronised with an accuracy of the order of a nanosecond. At AERA there is dedicated hardware installed to reach this kind of accuracy making it suitable to test extensive air shower reconstruction using interferometry.

The Pierre Auger Observatory has a rich program of Outreach and Education that comprises a strong presence online and a variety of initiatives taking place at the local, regional and international levels [1]. The online presence is established by a dedicated outreach web page with extensive explanatory content on cosmic rays and a virtual tour to the observatory, as well as by social network accounts with regular posts for a total of about 6 600 followers [2]. Two of the initiatives with highest impact to the students and populations of the region are the Malargüe Science Fair and the Visitor Center of the observatory. The Science Fair happens every two years and involves students of several ages, from primary to adult schools in Argentina, in the development and presentation of science projects. Selected projects are presented in Malargüe and discussed with scientists of the Pierre Auger Collaboration. The last edition took place on November 2022 and counted 21 projects and more than 600 visitors, as reported in Fig. 1. The Auger Visitor Center, located at the observatory building in Malargüe, is permanently open to the public with an interactive exposition. The number of visitors, mainly from Argentina, has recovered in 2022 to pre-pandemic peak values of nearly 10 000 visitors per year. At the beginning of 2023, the center was renewed with additional exhibitors, such as an on-screen virtual assistant, new small-scale models of the observatory facilities, working detectors and a manned-balloon structure with goggles for a virtual-reality tour to the field. The Auger Collaboration is also engaged with initiatives promoted by international institutions …

JEM-EUSO is an international program for the development of space-based Ultra-High Energy Cosmic Ray observatories. The program consists of a series of missions which are either under development or in the data analysis phase. All instruments are based on a wide-field-of-view telescope, which operates in the near-UV range, designed to detect the fluorescence light emitted by extensive air showers in the atmosphere. We describe the simulation software ESAF in the framework of the JEM-EUSO program and explain the physical assumptions used. We present here the implementation of the JEM-EUSO, POEMMA, K-EUSO, TUS, Mini-EUSO, EUSO-SPB1 and EUSO-TA configurations in ESAF. For the first time ESAF simulation outputs are compared with experimental data.

With the knowledge and statistical power of over a decade and a half of measurements, the Auger Collaboration has developed, assessed, and refined robust methods for reconstructing the energies and arrival directions of the highest-energy cosmic rays from the signal and timing measurements of its surface detector array. Concurrently, the unearthing of an increasingly complex astrophysical scenario and tensions with hadronic interaction models have demanded the addition of primary mass as an observable measurable using the surface detector. Access to information on the mass hinges on the disentanglement of the electromagnetic and muonic components of extensive air showers. Consequently, an upgrade to the Observatory, AugerPrime, is being carried out by equipping existing water-Cherenkov stations with a 3.8 m2 Scintillator Surface Detector (SSD). The SSDs, with their high sensitivity to electrons and positrons, will provide samples of the lateral distribution of particles at the ground that complement those of the water-Cherenkov detectors, which are significantly more sensitive to muons. When used together, the two measurements enable extraction of the number of incident muons, which is a quantity that strongly correlates with primary mass. We describe the reconstruction methods being developed for application to measurements of the surface detector of the Observatory with a particular focus on the enhancement of these methods with data of the SSDs of AugerPrime. Results from the reconstruction of thousands of high-energy events already measured with deployed SSDs are also shown.

The recent observations of photons with energies of a few 1014 eV from decaying neutral pions, both from a direction coincident with a giant molecular cloud (HAWC J1825-134, Albert et al. 2021) and from the Galactic plane (Amenomori et al. 2021), provide evidence for an acceleration of cosmic rays to energies of several 1015 eV, and above, in the Galaxy. A dozen sources emitting photons with energies up to 1015 eV have even been reported (Cao et al. 2021a), and in at least one of them (LHAASO J2108+ 515, also in directional coincidence with a giant molecular cloud), these photons might have a hadronic origin (Cao et al. 2021b). Observations of these photons are key in probing the mechanisms of particle acceleration, completing the multi-messenger approach aimed at understanding the nonthermal processes producing cosmic rays. The detection of even higher-energy photons would be of considerable …

Mini-EUSO is a small orbital telescope with a field of view of , observing the night-time Earth mostly in 320-420 nm band. Its time resolution spanning from microseconds (triggered) to milliseconds (untriggered) and more than km of the ground covered, already allowed it to register thousands of meteors. Such detections make the telescope a suitable tool in the search for hypothetical heavy compact objects, which would leave trails of light in the atmosphere due to their high density and speed. The most prominent example are the nuclearites -- hypothetical lumps of strange quark matter that could be stabler and denser than the nuclear matter. In this paper, we show potential limits on the flux of nuclearites after collecting 42 hours of observations data.

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to observe ultrahigh-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky. Developed as a NASA Astrophysics Probe-class mission, POEMMA consists of two identical telescopes orbiting the Earth in a loose formation designed to observe extensive air showers (EAS) via air fluorescence and Cherenkov emissions. UHECRs and UHE neutrinos above 20 EeV are observed with the stereo fluorescence technique, while tau neutrinos above 20 PeV are observed via the optical Cherenkov signals produced by up-going EAS generated by the decay of Earth-emerging tau-leptons. The POEMMA satellites are designed to quickly re-orientate to follow up transient cosmic neutrino candidate sources and obtain unparalleled neutrino flux sensitivity. Both observation techniques and the instrument design are being validated by current and upcoming missions, such as Mini-EUSO and EUSO-SPB as part of the JEM-EUSO program, and the Terzina instrument onboard the NUSES SmallSat mission. We discuss the POEMMA science performance and the current roadmap to the POEMMA mission.

The field of UHECRs (Ultra-High energy cosmic Rays) and the understanding of particle acceleration in the cosmos, as a key ingredient to the behaviour of the most powerful sources in the universe, is of outmost importance for astroparticle physics as well as for fundamental physics and will improve our general understanding of the universe. The current main goals are to identify sources of UHECRs and their composition. For this, increased statistics is required. A space-based detector for UHECR research has the advantage of a very large exposure and a uniform coverage of the celestial sphere. The aim of the JEM-EUSO program is to bring the study of UHECRs to space. The principle of observation is based on the detection of UV light emitted by isotropic fluorescence of atmospheric nitrogen excited by the Extensive Air Showers (EAS) in the Earth's atmosphere and forward-beamed Cherenkov radiation reflected from the Earth's surface or dense cloud tops. In addition to the prime objective of UHECR studies, JEMEUSO will do several secondary studies due to the instruments' unique capacity of detecting very weak UV-signals with extreme time-resolution around 1 microsecond: meteors, Transient Luminous Events (TLE), bioluminescence, maps of human generated UV-light, searches for Strange Quark Matter (SQM) and high-energy neutrinos, and more. The JEM-EUSO program includes several missions from ground (EUSO-TA), from stratospheric balloons (EUSO-Balloon, EUSO-SPB1, EUSO-SPB2), and from space (TUS, Mini-EUSO) employing fluorescence detectors to demonstrate the UHECR observation from space and prepare the …

The detection of the cosmic-ray (CR) energy spectrum with surface detectors spans over six orders of magnitude in energy, from 1015 eV up to more than 1020 eV. It follows a power-law with a spectral index≃ 3 exhibiting five features identified by small deviations in the spectral index: the knee, the second knee, the ankle, the “instep”[1], and a suppression at the highest energies. Particularly, the second knee has been observed at∼ 1017 eV by several observatories as a steepening of the spectrum [2–6]. Its interpretation may be connected to the maximal energy of the accelerators in the Galaxy, considering that a gradual heavier composition has been observed at these energies [7], which is along the lines of the so-called Peters cycles [8]. The astrophysical interpretation of the acquired data is still delicate, mainly because the nature of the sources, the propagation effects, and the CR composition are strongly entwined. A signature of neutral particles such as photons and neutrinos around the second-knee may shed light on this problem, since they are not deflected by magnetic fields, thus providing valuable information about the acceleration processes in astrophysical objects.A more accurate understanding of the origin of the second knee may be possible if one observatory is capable of measuring all spectral features and the CR mass composition with a common energy scale. In this sense, the Pierre Auger Observatory extended its Surface Detector (SD) with the deployment of a433-m spaced triangular array (SD-433) of water-Cherenkov detectors (WCDs) to unveil the spectral region below 1017 eV.

As an underground multi-purpose neutrino detector with 20 kton liquid scintillator, Jiangmen Underground Neutrino Observatory (JUNO) is competitive with and complementary to the water-Cherenkov detectors on the search for the diffuse supernova neutrino background (DSNB). Typical supernova models predict 2-4 events per year within the optimal observation window in the JUNO detector. The dominant background is from the neutral-current (NC) interaction of atmospheric neutrinos with 12C nuclei, which surpasses the DSNB by more than one order of magnitude. We evaluated the systematic uncertainty of NC background from the spread of a variety of data-driven models and further developed a method to determine NC background within 15\% with {\it {in}}{\it {situ}} measurements after ten years of running. Besides, the NC-like backgrounds can be effectively suppressed by the intrinsic pulse-shape discrimination (PSD) capabilities of liquid scintillators. In this talk, I will present in detail the improvements on NC background uncertainty evaluation, PSD discriminator development, and finally, the potential of DSNB sensitivity in JUNO.

The Pierre Auger Observatory, which is the largest air-shower experiment in the world, offers unprecedented exposure to neutral particles at the highest energies. Since the start of data collection more than 18 years ago, various searches for ultra-high-energy (UHE, E≳1017eV) photons have been performed, either for a diffuse flux of UHE photons, for point sources of UHE photons or for UHE photons associated with transient events such as gravitational wave events. In the present paper, we summarize these searches and review the current results obtained using the wealth of data collected by the Pierre Auger Observatory.
