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…
Gammapy: A Python package for gamma-ray astronomy
Axel Donath, Régis Terrier, Quentin Remy +42
In this article, we present Gammapy, an open-source Python package for the analysis of astronomical -ray data, and illustrate the functionalities of its first long-term-support…
Optical intensity interferometry lab tests in preparation of stellar diameter measurements at IACTs at GHz photon rates
Andreas Zmija, Naomi Vogel, Gisela Anton +4
Astronomical intensity interferometry enables quantitative measurements of the source geometry by measuring the photon fluxes in individual telescopes and correlating them, rather…
Application of Graph Networks to background rejection in Imaging Air Cherenkov Telescopes
Jonas Glombitza, Vikas Joshi, Benedetta Bruno +1
Imaging Air Cherenkov Telescopes (IACTs) are essential to ground-based observations of gamma rays in the GeV to TeV regime. One particular challenge of ground-based gamma-ray astro…
Validating Monte Carlo simulations for an analysis chain in H.E.S.S
Fabian Leuschner, Johannes Schäfer, Simon Steinmassl +6
Imaging Air Cherenkov Telescopes (IACTs) detect very high energetic (VHE) gamma rays. They observe the Cherenkov light emitted in electromagnetic shower cascades that gamma rays in…
