Are Single-Zone Emission models Sufficient to Explain GRB 220426A and GRB 230812B?
Soumya Gupta, Sunder Sahayanathan, Saharsh Shanu +1
Gamma-ray bursts (GRBs) are the universe's most energetic phenomena (isotropic luminosity ergs/s) lasting for a very short duration ( milliseconds -…
Modelling the Time-variable Broadband Emission and Correlation Study of FSRQ S5 1044+71
Sajad Ahanger, Shah Zahir, Sunder Sahayanathan +3
We present a detailed temporal and spectral analysis of the blazar S5\,1044+71 using multi-wavelength data obtained from the \emph{Fermi}-LAT and Swift-XRT/UVOT telescopes. Applyin…
Time-resolved spectro-polarimetric analysis of extremely bright GRB 230307A: Possible Evidence of evolution from photospheric to synchrotron dominated emission
Soumya Gupta, Rahul Gupta, Tanmoy Chattopadhayay +11
The radiation mechanisms powering Gamma-ray bursts (GRBs) and their physical processes remain one of the unresolved questions in high-energy astrophysics. Spectro-polarimetric obse…
Investigation of the Gamma-Ray Bursts prompt emission under the relativistically expanding fireball scenario
Soumya Gupta, Sunder Sahayanathan
The spectral properties of a composite thermal emission arising from a relativistic expanding fireball can be remarkably different from the Planck function. We perform a detailed s…
