A numerical jet model for the prompt emission of gamma-ray bursts
Ruben Farinelli, Rupal Basak, Lorenzo Amati +2
Gamma-ray bursts (GRBs) are known to be highly collimated events, and are mostly detectable when they are seen on-axis or very nearly on-axis. However, GRBs can be seen from off-ax…
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…
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…
Role of THESEUS in Understanding the Radiation Mechanism of GRB Prompt Emission
R. Basak
The radiation process of GRB prompt emission remains highly debated till date. Though a smoothly broken powerlaw function like Band provides an excellent fit to most of the cases,…
Surprise in simplicity: an unusual spectral evolution of a single pulse GRB 151006A
R. Basak, S. Iyyani, V. Chand +4
We present a detailed analysis of GRB 151006A, the first GRB detected by Astrosat CZT Imager (CZTI). We study the long term spectral evolution by exploiting the capabilities of \em…
Prompt emission polarimetry of Gamma Ray Bursts with ASTROSAT CZT-Imager
Tanmoy Chattopadhyay, Santosh V. Vadawale, E. Aarthy +10
X-ray and Gamma-ray polarization measurements of the prompt emission of Gamma-ray bursts (GRBs) are believed to be extremely important for testing various models of GRBs. So far, t…
