Investigating Temporal Features in Swift GRB Afterglows: A Comparative Study of UVOT and XRT Data

Amit K. Ror, S. B. Pandey, S. R. Oates +4

This study presents a statistical analysis of optical light curves (LCs) of 200 UVOT-detected GRBs from 2005 to 2018. We have categorised these LCs based on their distinct morpholo…

X-ray and gamma-ray timing of GRB 180720B, GRB 181222B, GRB 211211A and GRB 220910A observed with Fermi and ASIM

M. D. Caballero-Garcia, E. Gogus, J. Navarro-Gonzalez +20

We present a timing study of the gamma and X-ray observations and analysis of a sample of bright gamma-ray bursts (GRBs; i.e. GRB 180720B, GRB 181222B, GRB 211211A and GRB 220910A)…

The core collapse of a 16.5 M star

Amar Aryan, Shashi Bhushan Pandey, Rahul Gupta +2

We investigate the 1D stellar evolution of a 16.5 M zero-age main-sequence star having different initial rotations. Starting from the pre-main-sequence, the models evolve…

Prompt and afterglow analysis of the Fermi-LAT detected GRB 230812B

Amit K. Ror, S. B. Pandey, A. Aryan +2

Prompt emission of GRB 230812B stands out as one of the most luminous events observed by both the Fermi-GBM and LAT. Prompt emission spectral analysis (both time-integrated and res…
