Probing Neutron Star Equation of State Universality with Gravitational Waves
Praveer Tiwari, Ajit Kumar Mehta, K. G. Arun
Current neutron star equation-of-state inferences assume that a common equation of state describes all neutron stars. However, {poorly understood dense-matter physics may give rise…
Testing the spin-induced multipole moments of compact binary coalescences using the flexible theory-independent framework
Elise M. Sänger, Alessandra Buonanno, Ajit Kumar Mehta +1
According to the no-hair theorem, the multipole moments of an electrically neutral black hole in general relativity are entirely determined by its mass and spin. However, this is n…
The diffraction-lensing interpretation of GW231123 with astrophysical priors
Mark Ho-Yeuk Cheung, Digvijay Wadekar, Matias Zaldarriaga +3
GW231123, if unlensed, is a rare binary black hole merger with high masses and high spins for both progenitors. We show that the signal is better fitted by a lower-mass, lower-spin…
Discovery of Interpretable Surrogates via Agentic AI: Application to Gravitational Waves
Tousif Islam, Digvijay Wadekar, Tejaswi Venumadhav +4
Fast surrogate models for expensive simulations are now essential across the sciences, yet they typically operate as black boxes. We present \texttt{GWAgent}, a large language mode…
GW190711_030756 and GW200114_020818: astrophysical interpretation of two asymmetric binary black hole mergers in the IAS catalog
Tousif Islam, Tejaswi Venumadhav, Digvijay Wadekar +6
We provide a comprehensive analysis of GW190711_030756 and GW200114_020818, two of the most significant binary black hole merger candidates in the IAS catalog, with probabilities o…
Searching for precessing binary systems with mode-by-mode filtering and marginalization
Zihan Zhou, Digvijay Wadekar, Javier Roulet +8
Nearly all previous binary black hole searches in LIGO--Virgo--KAGRA (LVK) gravitational wave data have assumed that the component spins are aligned with the orbital angular moment…
