Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek
The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…
Performance update of an event-type based analysis for the Cherenkov Telescope Array
Juan Bernete, Orel Gueta, Tarek Hassan +3
The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional ap…
Science verification of the new FlashCam-based camera in the 28m telescope of H.E.S.S
Gerd Pühlhofer, Konrad Bernlöhr, Baiyang Bi +13
In October 2019 the central 28m telescope of the H.E.S.S. experiment has been upgraded with a new camera. The camera is based on the FlashCam design which has been developed in vie…
Validation of open-source science tools and background model construction in -ray astronomy
Lars Mohrmann, Andreas Specovius, Domenico Tiziani +4
In classical analyses of -ray data from IACTs, such as H.E.S.S., aperture photometry, or photon counting, is applied in a (typically circular) region of interest (RoI) encompass…
Towards the First Catalog of Fermi-LAT sources below 100 MeV
Giacomo Principe, Dmitry Malyshev, Stefan Funk
Previous analyses of point sources in the gamma-ray range were done either below 30 MeV or above 100 MeV. Below 30 MeV, the imaging Compton telescope (COMPTEL) onboard NASA's Compt…
Point Source Detection and Flux Determination with PGWave
Giacomo Principe, Dmitry Malyshev
One of the largest uncertainties in the Point Source (PS) studies, at Fermi-LAT energies, is the uncertainty in the diffuse background. In general there are two approaches for PS a…
