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…
Intruder in a two-dimensional granular system: statics and dynamics of force networks in an experimental system experiencing stick-slip dynamics
R. Basak, R. Kozlowski, L. A. Pugnaloni +4
In quasi-two-dimensional experiments with photoelastic particles confined to an annular region, an intruder constrained to move in a circular path halfway between the annular walls…
SALT long-slit spectroscopy of HE 0435-4312: fast displacement in the Mg II emission line
J. Sredzinska, B. Czerny, K. Hryniewicz +6
The Mg II emission line is visible in the optical band for intermediate redshift quasars (0.4 < z < 1.6) and it is thus an extremely important tool to measure the black hole mass a…
AstroSat CZT Imager observations of GRB 151006A: timing, spectroscopy, and polarisation study
A. R. Rao, Vikas Chand, M. K. Hingar +24
AstroSat is a multi-wavelength satellite launched on 2015 September 28. The CZT Imager of AstroSat on its very first day of operation detected a long duration gamma-ray burst (GRB)…
The THESEUS space mission concept: science case, design and expected performances
L. Amati, P. O'Brien, D. Goetz +208
THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-…
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,…
