Search for Gravitational-lensing Signatures in the Full Third Observing Run of the LIGO–Virgo Network

R. Abbott, H. Abe, F. Acernese, K. Ackley et autres

Abstract Gravitational lensing by massive objects along the line of sight to the source causes distortions to gravitational wave (GW) signals; such distortions may reveal information about fundamental physics, cosmology, and astrophysics. In this work, we have extended the search for lensing …

Search of the early O3 LIGO data for continuous gravitational waves from the Cassiopeia A and Vela Jr. supernova remnants

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

We present directed searches for continuous gravitational waves from the neutron stars in the Cassiopeia A (Cas A) and Vela Jr. supernova remnants. We carry out the searches in the LIGO detector data from the first six months of the third Advanced …

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 …
