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…

The simulation chain for the Terzina Cherenkov telescope on board the NUSES space mission

M. Abdullahi, R. Aloisio, F. Arneodo +74

The Terzina telescope is designed to detect ultra-high energy cosmic rays (UHECRs) and Earth-skimming neutrinos from a 550 km low-Earth orbit (LEO) by observing Cherenkov light emi…

Gamma-rays and Neutrinos from Giant Molecular Cloud Populations in the Galactic Plane

Abhijit Roy, Jagdish C. Joshi, Martina Cardillo +3

The recent IceCube detection of significant neutrino flux from the inner Galactic plane has provided us valuable insights on the spectrum of cosmic rays in our Galaxy. This flux ca…

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,…

Monte Carlo Simulation of CRAND Protons Trapped at Low Earth Orbits

Ritabrata Sarkar, Abhijit Roy

The Cosmic Ray Albedo Neutron Decay (CRAND) is believed to be the principal mechanism for the formation of inner proton radiation belt -- at least for relatively higher energy part…

Detection of Crab radiation with a meteorological balloon borne phoswich detector

Ritabrata Sarkar, Sandip K. Chakrabarti, Debashis Bhowmick +2

We use existing light weight balloon facility of Indian Centre for Space Physics to detect the X-ray radiation from Crab pulsar with a phoswich detector. We present the design cons…
