Flaring activity from magnetic reconnection in BL Lacertae
S. Agarwal, B. Banerjee, A. Shukla +7
The evolution of the spectral energy distribution during flares constrains models of particle acceleration in blazar jets. The archetypical blazar BL Lac provided a unique opportun…
A numerical study on the role of instabilities on multi-wavelength emission signatures of blazar jets
Sriyasriti Acharya, Bhargav Vaidya, Indu Kalpa Dihingia +2
Blazars, a class of active galaxies whose jets are relativistic and collimated flows of plasma directed along the line of sight and are prone to a slew of magneto-hydrodynamic (MHD…
Long-term optical and ray variability of the blazar PKS~1222+216
Savithri H. Ezhikode, Amit Shukla, Gulab C. Dewangan +4
The ray emission from flat-spectrum radio quasars (FSRQs) is thought to be dominated by the inverse Compton scattering of the external sources of photon fields, e.g., accretion…
GeV emission from a compact binary merger
Alessio Mei, Biswajit Banerjee, Gor Oganesyan +9
An energetic -ray burst (GRB), GRB 211211A, was observed on 2021 December 11 by the Neil Gehrels Swift Observatory. Despite its long duration, typically associated with burs…
Galactic and Extragalactic Sources of Very High Energy Gamma-rays
D. Bose, V. R. Chitnis, P. Majumdar +1
Very high energy γ-rays are one of the most important messengers of the non-thermal Universe. The major motivation of very high energy γ-ray astronomy is to find sources of high en…
Gamma-ray signatures from pair cascades in recombination-line radiation fields
Christoph Wendel, Josefa Becerra González, Amit Shukla +2
Beams of ultra-relativistic electrons in blazar jets develop pair cascades interacting with ambient soft photons. Employing coupled kinetic equations with escape terms, we model th…
