Parametrized tests of general relativity using eccentric compact binaries
Sajad A. Bhat, Pankaj Saini, Marc Favata +3
Astrophysical population simulations predict that a subset of dynamically formed binary black holes (BBHs) may possess eccentricity at a gravitational wave (GW) frequ…
Rates and beaming angles of GRBs associated with compact binary coalescences
Shasvath J. Kapadia, Dimple, Dhruv Jain +3
Some, if not all, binary neutron star (BNS) coalescences, and a fraction of neutron - star black hole (NSBH) mergers, are thought to produce sufficient mass-ejection to power Gamma…
Reconstructing the Genealogy of LIGO-Virgo Black Holes
Parthapratim Mahapatra, Debatri Chattopadhyay, Anuradha Gupta +4
We propose a Bayesian inference framework to predict the merger history of LIGO-Virgo binary black holes (BHs), whose binary components may have undergone hierarchical mergers in t…
Diversity in Fermi/GBM Gamma Ray Bursts: New insights from Machine Learning
Dimple, K. Misra, K. G. Arun
Classification of gamma-ray bursts (GRBs) has been a long-standing puzzle in high-energy astrophysics. Recent observations challenge the traditional short vs. long viewpoint, where…
Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
