A Multi-Mission Detection Framework for High-Energy Transients: Application to a 13-year Fermi/GBM and Swift/BAT Sample
Ariel Perera, Barak Zackay, Tejaswi Venumadhav
The detection of faint high-energy transients is becoming increasingly important in time-domain and multi-messenger astronomy, particularly for identifying electromagnetic counterp…
Expanding the Population of Short Gamma-Ray Transients with a Coherent Fermi/GBM Search. A 13-year catalog of short GRBs
Ariel Perera, Barak Zackay, Tejaswi Venumadhav
In this paper, we present an archival search for short gamma-ray bursts (sGRBs) over 13 years (2013-2025) of Fermi/GBM data using a Poisson matched-filter pipeline that performs a…
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…
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…
A New Search Pipeline for Short Gamma Ray Bursts in Fermi/GBM Data -- A 50% Increase in the Number of Detections
Ariel Perera, Barak Zackay, Tejaswi Venumadhav
In this paper, we present the development and the results of a new search pipeline for short gamma-ray bursts (sGRBs) in the publicly available data from the Gamma-Ray Burst Monito…
gwharmone: first data-driven surrogate for eccentric harmonics in binary black hole merger waveforms
Tousif Islam, Tejaswi Venumadhav, Ajit Kumar Mehta +6
We present gwharmone, the first data-driven surrogate model for eccentric harmonics (as well as the full radiation content) of the dominant quadrupolar mode in eccentric, non-spinn…
