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-Ray Bursts (GRBs). However, this fraction, as well as the distributio

Electromagnetic observations of the first binary Neutron Star (BNS) merger GW170817 has established that relativistic jets can be successfully launched in BNS mergers. Typically, such jets produce emission in two phases: $\gamma$-ray prompt emission

Assuming all binary Neutron Star mergers produce Short Gamma Ray Bursts (SGRBs), we combine the merger rates of binary Neutron Stars (BNS) from population synthesis studies, the sensitivities of advanced Gravitational Wave (GW) interferometer network

On 17th August 2017, Gravitational Wave (GW) detector network AdvLIGO/VIRGO reported the first ever detection of a merging neutron star binary, GW170817 [1]. A spatially and temporally coincident gamma-ray signal, short Gamma Ray Burst (GRB) 170817A,

The gender disparity in the Indian physics profession is stark, even compared to other scientific disciplines, reflecting the global trend. While the drivers of the disparity are clearly multiple and complex, we present examples that demonstrate that

Advanced LIGO and Virgo detectors reported the first binary neutron star merger candidate in the third observing run, S190425z, on 25th April 2019. A weak $\gamma$-ray excess was reported nearly coincidentally by the INTEGRAL satellite which accident
Gravitational-wave detected neutron star mergers provide an opportunity to investigate short gamma-ray burst (GRB) jet afterglows without the GRB trigger. Here we show that the post-peak afterglow decline can distinguish between an initially ultra-re

Context. Long gamma-ray bursts (GRBs) are produced during the dramatic deaths of massive stars with very short lifetimes, meaning that they explode close to the birth place of their progenitors. Over a short period they become the most luminous objec

This review focuses on the physics of Gamma Ray Bursts probed through their radio afterglow emission. Even though radio band is the least explored of the afterglow spectrum, it has played an important role in the progress of GRB physics, specifically
