Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765

The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe. This motivates directi…

Biased parameter inference of eccentric, spin-precessing binary black holes

Divyajyoti, Isobel M. Romero-Shaw, Vaishak Prasad +8

While the majority of gravitational wave (GW) events observed by the LIGO and Virgo detectors are consistent with mergers of binary black holes (BBHs) on quasi-circular orbits, som…

GW250114: testing Hawking's area law and the Kerr nature of black holes

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785

The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
