Scrutinizing the 2020 multiwavelength outburst of PKS 0903-57 through observations with H.E.S.S

A. Acharyya, F. Aharonian, F. Ait Benkhali +138

The blazar PKS 0903-57 has recently been classified as a flat spectrum radio quasar at a redshift of . In March and April 2020, Fermi-LAT and AGILE reported tremendous ac…

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…

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…

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…
