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…
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…
Advanced modelling of Night Sky Background light for Imaging Atmospheric Cherenkov Telescopes
Gerrit Roellinghoff, Samuel T. Spencer, Stefan Funk
A significant source of noise for Imaging Atmospheric Cherenkov Telescopes (IACTs), which are designed to measure air showers caused by astrophysical gamma rays, is optical light e…
Investigating the effect of hadronic models on IACT images
Benedetta Bruno, Rodrigo Guedes Lang, Luan Bonneau Arbeletche +2
The predictions of hadronic interaction models for cosmic-ray induced air showers contain inherent uncertainties due to limitations of available accelerator data. This leads to dif…
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…
