Unified remnant models for aligned-spin, precessing, and eccentric binary black hole mergers
Tousif Islam, Digvijay Wadekar, Gaurav Khanna
Using approximately numerical-relativity (NR) simulations spanning mass ratios up to and black-hole-perturbation-theory (BHPT) simulations extending to $q=100…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
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…
gwBenchmarks: Stress-Testing LLM Agents on High-Precision Gravitational Wave Astronomy
Tousif Islam, Digvijay Wadekar, Zihan Zhou
Modern gravitational wave astronomy relies on modeling tasks that often require months of graduate-level effort, including building fast waveform surrogates from expensive numerica…
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…
Recoil kicks from binary black hole mergers in GWTC catalogs: implications for retention and hierarchical mergers
Tousif Islam
We infer recoil (kick) velocities for both individual binary black hole (BBH) mergers and candidate intermediate-mass black hole events, as well as for the BBH populations inferred…
Kick matters: The impact of a new recoil model on the retention of hierarchical black-hole remnants in globular clusters
Tousif Islam, Digvijay Wadekar, Konstantinos Kritos
In globular clusters, hierarchical mergers are among the most promising pathways to forming massive black holes such as GW231123. A key factor determining whether a merger-remnant…
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…
Progenitor of the recoiling super-massive black hole RBH-1 identified using HST/JWST imaging
Tousif Islam, Tejaswi Venumadhav, Digvijay Wadekar
Using a combination of \textit{Hubble Space Telescope} and \textit{James Webb Space Telescope} imaging, a runaway supermassive black hole (RBH-1) was recently identified with an in…
