Study of the Ultra-Long GRB 220627A: Exploring a Possible Blue Supergiant Collapsar Origin
Ayush Garg, Amit Shukla, Dorottya Szécsi +1
Ultra-long gamma-ray bursts (ul-GRBs) challenge standard collapsar models because their extreme durations require central engines active for s. While the prompt…
Role of magnetic reconnection in blazar variability using numerical simulation
Chandan Kumar Das, Bhargav Vaidya, Amit Shukla +2
Fast -ray variability in blazars remains a central puzzle in high-energy astrophysics, challenging standard shock acceleration models. Blazars, a subclass of active galactic nuc…
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…
Binary black holes in magnetized AGN disks
Raj Kishor Joshi, Aryan Bhake, Biswajit Banerjee +7
Stellar-mass binary black hole (BBH) mergers occurring within the disks of active galactic nuclei (AGN) are promising sources for gravitational waves detectable by the LIGO, Virgo,…
Broadband Modelling of GRB 230812B Afterglow: Implications for VHE -ray Detection with IACTs
Shraddha Mohnani, Biswajit Banerjee, Davide Miceli +13
A significant fraction of the energy from the -ray burst (GRB) jets, after powering the keV-MeV emission, forms an ultra-relativistic shock propagating into the circumburst medi…
Constraining -ray dissipation site in gravitationally lensed quasar -- PKS 1830211
Sushmita Agarwal, Amit Shukla, Pranjali Sharma
Variable -ray flares upto minute timescales reflect extreme particle acceleration sites. However, for high-redshift blazars, the detection of such rapid variations remains limit…
Bridging Simulations of Kink Instability in Relativistic Magnetized Jets with Radio Emission and Polarisation
Nikita Upreti, Bhargav Vaidya, Amit Shukla
Relativistic outflows emanating from active galactic nuclei can extend up to kiloparsec scales in length, displaying a variety of complex morphologies. This study explores the intr…
Imprint of "Local Opacity" Effect in Gamma-Ray Spectrum of Blazar Jet
Sushmita Agarwal, Amit Shukla, Karl Mannheim +2
Relativistic jets from accreting supermassive black holes at cosmological distances can be powerful emitters of -rays. However, the precise mechanisms and locations responsible…
