Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, sudden frequency ch…
Thermodynamics of Black Holes, far from Equilibrium
Abhay Ashtekar, Daniel E. Paraizo, Jonathan Shu
As in thermodynamics, the celebrated first law of black hole mechanics relates infinitesimal changes in the properties of nearby equilibrium states of black holes (without referenc…

Testing general relativity with amplitudes of subdominant gravitational-wave modes
Ish Gupta, Purnima Narayan, Lionel London +2
We present an improved subdominant-mode amplitude (SMA) test of general relativity (GR), which probes amplitude-level deviations in the higher-order modes of gravitational-wave (GW…
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…
Simulations of Spinning Binary Black Hole Mergers
Estuti Shukla, Alireza Rashti, Rossella Gamba +2
We present the second release of the waveform catalog, comprising four new quasi-circular, non-precessing, spinning binary black hole simulations. These simu…
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…

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…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
