Characterisation of the Atmosphere in Very High Energy Gamma-Astronomy for Imaging Atmospheric Cherenkov Telescopes

Dijana Dominis Prester, Jan Ebr, Markus Gaug +8

Ground-based observations of Very High Energy (VHE) gamma rays from extreme astrophysical sources are significantly influenced by atmospheric conditions. This is due to the atmosph…

Matching the Vilkovisky-DeWitt Effective Action of Quantum Gravity to String Theory

Xavier Calmet, Elias Kiritsis, Folkert Kuipers +1

In this work, we discuss the matching of the Vilkovisky-DeWitt effective action of quantum gravity to an example of an ultra-violet complete theory of quantum gravity. We show how…

Direct Comparison of SiPM and PMT Sensor Performances in a large-size imaging air Cherenkov telescope

A. Hahn, R. Mirzoyan, A. Dettlaff +3

The peak photon detection efficiency (PDE) of silicon photomultipliers (SiPMs) can be as good or better than the PDE of photomultiplier tubes (PMTs). There are experiments where th…

A computation of two-loop six-point Feynman integrals in dimensional regularization

Johannes M. Henn, Antonela Matijašić, Julian Miczajka +3

We compute three families of two-loop six-point massless Feynman integrals in dimensional regularization, namely the double-box, the pentagon-triangle, and the hegaxon-bubble famil…

The variability patterns of the TeV blazar PG 1553+113 from a decade of MAGIC and multi-band observations

MAGIC Collaboration, H. Abe, S. Abe +264

PG 1553+113 is one of the few blazars with a convincing quasi-periodic emission in the gamma-ray band. The source is also a very high-energy (VHE; >100 GeV) gamma-ray emitter. To b…

Performance and first measurements of the MAGIC Stellar Intensity Interferometer

MAGIC Collaboration, S. Abe, J. Abhir +217

In recent years, a new generation of optical intensity interferometers has emerged, leveraging the existing infrastructure of Imaging Atmospheric Cherenkov Telescopes (IACTs). The…
