Event types in H.E.S.S.: a combined analysis for different telescope types and energy ranges
Rodrigo Guedes Lang, Tim Unbehaun, Lars Mohrmann +3
Imaging atmospheric Cherenkov telescopes (IACTs) are the main technique for detecting gamma rays with energies between tens of GeV and hundreds of TeV. Amongst them, the High Energ…
H.E.S.S. observations of composite Seyfert-starburst galaxies
H. E. S. S. Collaboration, A. Acharyya, F. Aharonian +119
Context: Composite galaxies that contain both Seyfert and starburst components may produce very high-energy (VHE; >100 GeV) gamma-ray emission at a wide range of spatial scales, fr…
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…
A novel approach to optimizing the image cleaning performance of Imaging Atmospheric Cherenkov Telescopes: Application to a time-based cleaning for H.E.S.S
Jelena ÄeliÄ, Rodrigo Guedes Lang, Simon Steinmassl +2
This study introduces a time-based cleaning method for H.E.S.S. using CT5 in monoscopic mode and presents an optimization workflow for image-cleaning algorithms to enhance telescop…
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…
Improvements to monoscopic analysis for imaging atmospheric Cherenkov telescopes: Application to H.E.S.S
Tim Unbehaun, Rodrigo Guedes Lang, Anita Deka Baruah +7
Imaging atmospheric Cherenkov telescopes (IACTs) detect gamma rays by measuring the Cherenkov light emitted by secondary particles in the air shower when the gamma rays hit the atm…
