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…
Accelerated Time-domain Analysis for Gravitational Wave Astronomy
Vaishak Prasad
Most current compact-binary searches and parameter-estimation pipelines evaluate the Gaussian-noise likelihood approximately using frequency-domain inner products with great succes…
Multi-Segment Consistency Tests of General Relativity
Vaishak Prasad
As the LIGO-VIRGO-KAGRA Network of gravitational-wave detectors improves in sensitivity, accumulating hundreds of gravitational-wave detections per year, it becomes imperative to i…
Are black hole spins truly near-zero?
Vaishak Prasad, B. S. Sathyaprakash
The fourth gravitational-wave transient catalog, GWTC-4.0, reports 153 binary black hole mergers with false-alarm rates . Chirp masses are typically measured w…
A Maximum Entropy Conjecture for Black Hole Mergers
Monica Rincon-Ramirez, Nathan K. Johnson-McDaniel, Eugenio Bianchi +3
The final state of a binary black hole merger is predicted with high precision by numerical relativity, but could there be a simple thermodynamic principle within general relativit…
