Multiwavelength Observations of Gamma-ray bursts

My primary research focus is on Gamma-Ray Bursts (GRBs), the most energetic and enigmatic phenomena in the Universe. I utilize multi-wavelength data from various ground and space-based telescopes, including the NASA Fermi and Swift missions. My research covers a wide spectrum of topics including: 

Prompt Emission: Investigating the initial burst of gamma rays and the mechanisms that produce this extraordinary release of energy.

Spectro-Polarimetric Analysis: Analyzing the spectrum and polarization of GRB emissions to gain insights into the physical processes and structures of the GRB jets. This work also aims to address fundamental and unresolved questions in high-energy physics, such as the radiation mechanisms and jet composition of bright GRBs.

Afterglow Studies: Understanding the fading emission following the initial burst, which can span across X-ray, optical, and radio wavelengths.

Progenitor Models: Exploring the origins of GRBs, including the collapse of massive stars and mergers of compact objects.

GRB Environments: Studying the environments in which GRBs occur and their implications for the bursts' characteristics and their role in the Universe.
