The Origin of Multi-TeV Gamma-rays in LHAASO J0341+5258 via Cosmic Ray Illumination of Molecular Clouds
Abhijit Roy, Alan Sunny, Martina Cardillo +2
We investigate the origin of the ultra-high-energy -ray emission detected by the Large High Altitude Air Shower Observatory (LHAASO) from the source LHAASO J0341+5258, which has…
Dissecting the radiation mechanism of short GRB~160821B through multi-wavelength modelling
Ankur Ghosh, Monica Barnard, Jagdish C. Joshi +1
GRB~160821B is the only short GRB detected to date at very high energy (VHE, GeV). At a redshift , it was detected by MAGIC telescopes approximately four hou…
Modelling multiwavelength afterglows of the VHE-GRB population
Monica Barnard, Ankur Ghosh, Jagdish C. Joshi +1
The recent detection of very high energy (VHE, 100 GeV) -ray emission from gamma-ray bursts (GRBs) has provided new insights into afterglow physics. Understanding the…
Spatio-spectral-temporal Modelling of Two Young Pulsar Wind Nebulae
A. Kundu, Jagdish C. Joshi, C. Venter +5
Recent observations of a few young pulsar wind nebulae (PWNe) have revealed their morphologies in some detail. Given the availability of spatio-spectral-temporal data, we use our m…
Very high-energy gamma rays from GRB 180720B and GRB 190829A with external Compton emission
Monica Barnard, Soebur Razzaque, Jagdish C. Joshi
Gamma-ray bursts (GRBs) comprise of short, bright, energetic flashes of emission from extragalactic sources followed by a longer afterglow phase of decreased brightness. Recent dis…
Interpreting the GeV-TeV Gamma-Ray Spectra of Local Giant Molecular Clouds using GEANT4 Simulation
Abhijit Roy, Jagdish C. Joshi, Martina Cardillo +1
Recently, the Fermi-LAT gamma-ray satellite has detected six Giant Molecular Clouds (GMCs) located in the Gould Belt and the Aquila Rift regions. In half of these objects (Taurus,…
