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 i…

High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S

F. Aharonian, F. Ait Benkhali, J. Aschersleben +144

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…

Very-high-energy -ray emission from young massive star clusters in the Large Magellanic Cloud

F. Aharonian, F. Ait Benkhali, J. Aschersleben +129

The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant am…

Cosmic rays cannot explain the high ionisation rates in the Galactic centre

Sruthiranjani Ravikularaman, Sarah Recchia, Vo Hong Minh Phan +1

The H ionisation rate in the central molecular zone, located in the Galactic centre, is estimated to be , based on observations of H…

Indication of a fast ejecta fragment in the atomic cloud interacting with the southwestern limb of SN 1006

R. Giuffrida, M. Miceli, S. Ravikularaman +5

Supernova remnants interacting with molecular/atomic clouds are interesting X-ray sources to study broadband nonthermal emission. X-ray line emission in these systems can be produc…

Cosmic ray production in superbubbles

Thibault Vieu, Stefano Gabici, Vincent Tatischeff +1

We compute the production of cosmic rays in the dynamical superbubble produced by a cluster of massive stars. Stellar winds, supernova remnants and turbulence are found to accelera…
