X-ray Flares in Gamma-Ray Bursts at High and Very-High-Energies
Pawan Tiwari, Biswajit Banerjee, Gor Oganesyan +5
A significant fraction of GRB early afterglows exhibit fast and bright X-ray flares, discovered by Swift X-ray Telescope. Their rapid temporal variability and spectral evolution ha…

Detection of TeV emission during early afterglow from poorly localized GRBs with ground based IACTs
S. Macera, B. Banerjee, M. Seglar-Arroyo +10
Gamma-ray bursts (GRBs) are among the most luminous and rapidly evolving transients in the Universe. While space-based instruments have extended GRB observations up to energies of…

From X-rays to High-Energy Gamma-rays: A Comprehensive Multi-Wavelength Study of Early Gamma-Ray Burst Afterglows
P. Tiwari, B. Banerjee, D. Miceli +8
Gamma-ray Bursts (GRBs) generate powerful relativistic jets that inject a large amount of energy into their surrounding environment, producing blast waves that accelerate particles…
