Testing Gamma/Hadron Separation for Ultra-High-Energy Cherenkov Astronomy
Sruthiranjani Ravikularaman, Felix Riehn, Dominik Elsaesser
Dark100 is a planned array of six telescopes, using the Panoramic Search for Extraterrestrial Intelligence (PANOSETI) telescope system. It will operate as an imaging atmospheric Ch…
Can cosmic rays explain the high ionisation rates in the Galactic centre?
Sruthiranjani Ravikularaman, Sarah Recchia, Vo Hong Minh Phan +1
The Central Molecular Zone (CMZ), located in the centre of the Milky Way, is a roughly cylindrical structure of molecular gas extending up to parsecs around the supermassive black…
H.E.S.S. programme searching for VHE gamma rays associated with FRBs
F. Aharonian, A. Archaryya, J. Aschersleben +127
Fast Radio Bursts (FRBs) are highly energetic, extremely short-lived bursts of radio flashes. Despite extensive research, the exact cause of these outbursts remains speculative. Th…
The H.E.S.S. extragalactic sky survey with the first decade of observations
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +140
The results of the first extragalactic gamma-ray survey by the High Energy Stereoscopic System (H.E.S.S.) are presented. The survey comprises 2720 hours of very high-energy gamma-r…
Cosmic rays, gas and dust in the Central Molecular Zone I -- factors, cosmic-ray densities and dust opacities
H. X. Ren, Q. Remy, S. Ravikularaman +3
Our goal is to estimate the total gas mass in the direction of the Central Molecular Zone (CMZ), quantify the various uncertainties associated, and discuss the implications for the…
Detection of very-high-energy gamma-ray emission from Eta Carinae during its 2020 periastron passage
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +137
The colliding-wind binary system Carinae has been identified as a source of high-energy (HE, below 100\,GeV) and very-high-energy (VHE, above 100\,GeV) gamma rays…
