Most gamma-ray burst (GRB) X-ray afterglow light curves are characterised by a plateau, followed by a normal power-law decay, which is interpreted as afterglow emission, that is...

Gamma-ray bursts (GRBs) have traditionally been classified by duration into long (LGRBs) and short (SGRBs), with the former believed to originate from massive star collapses and...

Gamma-ray bursts (GRBs) are generally believed to originate from two distinct progenitors, compact binary mergers and massive collapsars. Traditional and some recent machine...

A sizeable fraction of gamma-ray burst (GRB) light curves (LCs) features a sequence of peaks, which holds information on the unknown way energy is released and dissipated into...

GRB221009A, initially detected as an X-ray transient by Swift, was later revealed to have triggered the Fermi satellite about an hour earlier, marking it as a post-peak...

A dedicated gamma-ray burst (GRB) afterglow observing program was performed between 2007 and 2016 with GROND, a seven-channel optical and near-infrared imager at the 2.2m...

We observed gamma-ray burst (GRB) 221009A using very long baseline interferometry (VLBI) with the European VLBI Network (EVN) and the Very Long Baseline Array VLBA), over a...

Long GRB hosts at z<1 are usually low-mass, low-metallicity star-forming galaxies. Here we present the most detailed, spatially resolved study of the host of GRB 171205A so...

At the dawn of the gamma-ray burst (GRB) afterglow era, a Cepheid-like correlation was discovered between the time variability V and the isotropic-equivalent peak luminosity...

Long gamma ray bursts (GRBs) are produced by the collapse of some very massive stars, which emit ultra-relativistic jets. When the jets collide with the interstellar medium they...

Gamma-ray bursts (GRBs) can be detected at cosmological distances, and therefore can be used to study the contents and phases of the early Universe. The 4-150keV wide-field...

Dark Gamma-Ray Bursts (GRBs) constitute a significant fraction of the GRB population. In this paper, we present the multiwavelength analysis (both prompt emission and afterglow)...

GRB 210731A was a long-duration (T_90_=22.5s) gamma-ray burst discovered by the Burst Alert Telescope aboard the Neil Gehrels Swift Observatory. Swift triggered the wide-field,...

There has been significant technological and scientific progress in our ability to detect, monitor and model the physics of gamma-ray bursts (GRBs) over the 50 years since their...

We observed GRB190114C (redshift z=0.4245), the first gamma-ray burst (GRB) ever detected at TeV energies, at optical and near-infrared wavelengths with several ground-based...

In the framework of the Standard Model Extension (SME), we present improved constraints on anisotropic Lorentz invariance and Charge-Parity-Time (CPT) violation by searching for...

Gamma-ray bursts (GRBs) are brief, intense, gamma-ray flashes in the universe, lasting from a few milliseconds to a few thousand seconds. For short gamma-ray bursts (sGRBs) with...

We report the earliest ever detection of optical polarization from a GRB forward shock (GRB 141220A), measured 129.5-204.3s after the burst using the multicolour RINGO3 optical...

We present a machine learning (ML) based method for automated detection of Gamma-Ray Burst (GRB) candidate events in the range 60-250 keV from the AstroSat Cadmium Zinc...

We present a comprehensive study of an unbiased sample of 150 nearby (median redshift, z = 0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-Sky Automated...
