GRB 200415A: A Short Gamma-Ray Burst from a Magnetar Giant Flare?
Jun Yang, Vikas Chand, Bin-Bin Zhang +16
The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we p…
Magnetar Giant Flare Originated GRB 200415A: Transient GeV emission, Time-Resolved Correlation, and Implications
Vikas Chand, Jagdish C. Joshi, Rahul Gupta +12
Giant flares (GFs) are unusual bursts from soft gamma-ray repeaters (SGRs) that release an enormous amount of energy in a fraction of a second. The afterglow emission of these SGR-…
Identifying Black Hole Central Engines in Gamma-Ray Bursts
Vidushi Sharma, Shabnam Iyyani, Dipankar Bhattacharya
The nature of the gamma-ray burst (GRB) central engine still remains an enigma. Entities widely believed to be capable of powering the extreme jets are magnetars and black holes. T…
Study of prompt emission of short gamma ray bursts using multi-color blackbody: a clue to the viewing angle
Shabnam Iyyani, Vidushi Sharma
The prompt emission of short gamma ray bursts (sGRBs) with known redshifts are analyzed using the model of multi-color blackbody which is interpreted as the emission from a non-dis…
Spectro-polarimetric analysis of prompt emission of GRB 160325A: jet with evolving environment of internal shocks
Vidushi Sharma, Shabnam Iyyani, Dipankar Bhattacharya +3
GRB 160325A is the only bright burst detected by AstroSat CZT Imager in its primary field of view to date. In this work, we present the spectral and polarimetric analysis of the pr…
Peculiar prompt emission and afterglow in H.E.S.S. detected GRB 190829A
Vikas Chand, Ankush Banerjee, Rahul Gupta +10
We present the results of a detailed investigation of the prompt and afterglow emission in the HESS detected GRB 190829A. Swift and Fermi observations of the prompt phase of this G…
