Constraints on dark photon dark matter using data from LIGO’s and Virgo’s third observing run

R. Abbott, T. D. Abbott, F. Acernese, K. Ackley et autres

We present a search for dark photon dark matter that could couple to gravitational-wave interferometers using data from Advanced LIGO and Virgo's third observing run. To perform this analysis, we use two methods, one based on cross-correlation of the strain channels in …

Constraints on the cosmic expansion history from GWTC-3

The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, H. Abe et autres

We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter $H(z)$, including its current value, the Hubble constant $H_0$. Each gravitational-wave (GW) signal provides the luminosity distance to the source and we estimate the …

GW190412: Observation of a binary-black-hole coalescence with asymmetric masses

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

We report the observation of gravitational waves from a binary-black-hole coalescence during the first two weeks of LIGO’s and Virgo’s third observing run. The signal was recorded on April 12, 2019 at 05∶30∶44 UTC with a network signal-to-noise ratio of 19. The …

All-sky search for long-duration gravitational-wave transients in the second Advanced LIGO observing run

B. P. Abbott, R. Abbott, T. D. Abbott, S. Abraham et autres

We present the results of a search for long-duration gravitational-wave transients in the data from the Advanced LIGO second observation run; we search for gravitational-wave transients of 2--500 s duration in the 24--2048 Hz frequency band with minimal assumptions about signal properties …

Search for transient gravitational waves in coincidence with short-duration radio transients during 2007–2013

B. P. Abbott, R. Abbott, T. D. Abbott, M. R. Abernathy et autres

We present an archival search for transient gravitational-wave bursts in coincidence with 27 single-pulse triggers from Green Bank Telescope pulsar surveys, using the LIGO, Virgo, and GEO interferometer network. We also discuss a check for gravitational-wave signals in coincidence with Parkes fast …

GW150914: First results from the search for binary black hole coalescence with Advanced LIGO

B. P. Abbott, R. Abbott, T. D. Abbott, M. R. Abernathy et autres

The recent announcement by LIGO of the detection of the gravitational-wave signal GW150914 has ignited tremendous interest. The two manuscripts highlighted here detail the impressive analysis performed by LIGO to identify a specific black hole binary merger as the source of GW150914. …
