Constraining Orbital Eccentricity of a Supermassive Black Hole Binary Candidate PKS 2131-0211
Avinash Kumar Paladi, A. Gopakumar, Sushmita Agarwal +1
A detailed analysis of the decades-long radio light curve of blazar PKS 2131-021 showed epochs of sinusoidal variations in the radio flux density time-series as detailed in O'Neill…
Hunting Very High-Energy (100 GeV) Emitting High-Synchrotron Peaked Blazars
Sushmita Agarwal, Vaidehi S. Paliya
Very-high energy (VHE; 100 GeV) -ray emission originates via some of the most extreme particle acceleration processes in the universe. Considering beamed active galactic nucl…
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…
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…
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…
