Probing into emission mechanisms of GRB 190530A using time-resolved spectra and polarization studies: Synchrotron Origin?
Rahul Gupta, S. Gupta, T. Chattopadhyay +47
Multi-pulsed GRB 190530A, detected by the GBM and LAT onboard \fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric…
Sub-MeV spectroscopy with AstroSat-CZT Imager for Gamma Ray Bursts
Tanmoy Chattopadhyay, Soumya Gupta, Vidushi Sharma +10
Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat has been a prolific Gamma-Ray Burst (GRB) monitor. While the 2-pixel Compton scattered events (100 - 300 keV) are used to extr…
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…
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…
Time varying polarized gamma-rays from GRB 160821A: evidence for ordered magnetic fields
Vidushi Sharma, Shabnam Iyyani, Dipankar Bhattacharya +8
GRB 160821A is the third most energetic gamma ray burst observed by the {\it Fermi} gamma-ray space telescope. Based on the observations made by Cadmium Zinc Telluride Imager (CZTI…
Violation of synchrotron line of death by the highly polarized
Vikas Chand, Tanmoy Chattopadhyay, S. Iyyani +7
is one of the brightest gamma-ray bursts (GRBs) observed with Gamma-ray Burst Monitor (GBM) in the energy range of keV, while at the same time it…
