Search for intermediate mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo

Intermediate-mass black holes (IMBHs) span the approximate mass range 100−105 M⊙, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the terrestrial detector network. Searches of the first two observing runs of Advanced LIGO and Advanced Virgo did not yield any significant IMBH binary signals. In the third observing run (O3), the increased network sensitivity enabled the detection of GW190521, a signal consistent with a binary merger of mass ∼150 M⊙ providing direct evidence of IMBH formation. Here, we report on a dedicated search of O3 data for further IMBH binary mergers, combining both modeled (matched filter) and model-independent search methods. We find some marginal candidates, but none are sufficiently significant to indicate detection of …

Constraints on the cosmic expansion history from GWTC-3

The discovery of a gravitational wave (GW) signal from a binary neutron star (BNS) merger (Abbott et al. 2017a) and the kilonova emission from its remnant (Coulter et al. 2017; Abbott et al. 2017b) provided the first GW standard siren measurement of the cosmic expansion history (Abbott et al. 2017c). As pointed out by Schutz (1986), the GW signal from a compact binary coalescence directly measures the luminosity distance to the source without any additional distance calibrator, earning these sources the name “standard sirens”(Holz & Hughes 2005). Measuring the cosmic expansion as a function of the cosmological redshift is one of the key avenues with which to explore the constituents of the universe, along with the other canonical probes such as the cosmic microwave background (CMB; Spergel et al. 2003, 2007; Komatsu et al. 2011; Ade et al. 2014, 2016; Aghanim et al. 2020), baryon acoustic oscillations …

All-sky Search for Continuous Gravitational Waves from Isolated Neutron Stars in the Early O3 LIGO Data

We present results of an all-sky search for continuous gravitational waves which can be produced by spinning neutron stars with an asymmetry around their rotation axis, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. Four different analysis methods are used to search in a gravitational-wave frequency band from 10 to 2048 Hz and a first frequency derivative from− 10− 8 to 10− 9 Hz/s. No statistically significant periodic gravitational-wave signal is observed by any of the four searches. As a result, upper limits on the gravitational-wave strain amplitude h 0 are calculated. The best upper limits are obtained in the frequency range of 100 to 200 Hz and they are∼ 1.1× 10− 25 at 95% confidence level. The minimum upper limit of 1.10× 10− 25 is achieved at a frequency 111.5 Hz. We also place constraints on the rates and abundances of nearby planetary-and asteroid-mass …

Observation of eccentric binary black hole mergers with second and third generation gravitational wave detector networks

We introduce an improved version of the eccentric, nonspinning, inspiral-Gaussian-process merger approximant (ENIGMA) waveform model that utilizes a more stable and robust numerical method to smoothly connect the analytical relativity-based inspiral evolution with the numerical relativity-based merger phase. We find that this ready-to-use model can:(i) produce physically consistent signals, without reporting any failures, when sampling over 1M samples that were randomly chosen over the m {1, 2}∈[5 M⊙, 50 M⊙] parameter space, and the entire range of binary inclination angles;(ii) produce waveforms within 0.04 seconds, averaged over 1000 iterations, from an initial gravitational wave frequency f GW= 15 Hz and at a sample rate of 8192 Hz; and (iii) reproduce the physics of quasicircular mergers, since its overlap with SEOBNRv4 waveforms is O≥ 0.99 assuming advanced LIGO zero detuned high power …

Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo

Advanced LIGO and Advanced Virgo are monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this paper we describe the data recorded by these instruments during their first and second observing runs. The main data products are gravitational-wave strain time series sampled at 16384 Hz. The datasets that include this strain measurement can be freely accessed through the Gravitational Wave Open Science Center at http://gw-openscience.org, together with data-quality information essential for the analysis of LIGO and Virgo data, documentation, tutorials, and supporting software.

Search for lensing signatures in the gravitational-wave observations from the first half of LIGO-Virgo's third observing run

Gravitational lensing occurs when a massive object bends spacetime in a way that focuses light rays toward an observer (see Bartelmann 2010, for a review). Lensing observations are widespread in electromagnetic astrophysics and have been used to, among other purposes, make a compelling case for dark matter (Clowe et al. 2004; Markevitch et al. 2004), discover exoplanets (Bond et al. 2004), and uncover massive objects and structures that are too faint to be detected directly (Coe et al. 2013).Similarly to light, when gravitational waves (GWs) travel near a galaxy or a galaxy cluster, their trajectories curve, resulting in gravitational lensing (Ohanian 1974; Thorne 1982; Deguchi & Watson 1986; Wang et al. 1996; Nakamura 1998; Takahashi & Nakamura 2003). For massive lenses, this changes the GW amplitude without affecting the frequency evolution (Wang et al. 1996; Dai & Venumadhav 2017; Ezquiaga et al …

Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO's and Advanced Virgo's first three observing runs

We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called p y s toch on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. A spherical harmonic decomposition method is employed to look for gravitational-wave emission from spatially-extended sources. Neither technique found evidence of gravitational-wave signals. Hence we derive 95% confidence-level upper limit sky maps on the gravitational-wave energy flux from broadband point sources, ranging from F α, Θ<(0.013–7.6)× 10− 8 erg cm− 2 s− 1 …

The Binary Black Hole Population after LIGO/Virgo's O3a Observing Run

Advanced LIGO and Virgo's O3a observing run has significantly expanded and refined our understanding of the stellar-mass binary black hole (BBH) population. Past detections have, to date, suggested a picture in which BBHs have low spins, masses concentrated below 45 solar masses, and preferentially equal mass ratios. In this talk, I will present the latest lessons learned during O3a, describing LIGO and Virgo's updated measurements of the spin, mass, and redshift distributions of BBHs. I will additionally speculate about the implications of these measurements for understanding the origin and evolution of compact binary mergers.
