Constraining neutron star properties with a new equation of state insensitive approach

Bhaskar Biswas, Sayak Datta

Instead of parameterizing the pressure-density relation of a neutron star (NS), one can parameterize its macroscopic properties such as mass (), radius (), and dimensionless…

4-OGC: Catalog of gravitational waves from compact-binary mergers

Alexander H. Nitz, Sumit Kumar, Yi-Fan Wang +5

We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star (BNS), binary black hole (BBH) and neutron star-black hole (NSBH) mergers. The catalog includes…

Population Properties of Gravitational-Wave Neutron Star--Black Hole Mergers

Jin-Ping Zhu, Shichao Wu, Ying Qin +3

Over the course of the third observing run of LIGO-Virgo-KAGRA Collaboration, several gravitational-wave (GW) neutron star--black hole (NSBH) candidates have been announced. By ass…

Searches for Gravitational Waves from Known Pulsars at Two Harmonics in the Second and Third LIGO-Virgo Observing Runs

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1694

We present a targeted search for continuous gravitational waves (GWs) from 236 pulsars using data from the third observing run of LIGO and Virgo (O3) combined with data from the se…
