Hadronic Re-Acceleration at the Crab Pulsar Wind Termination Shock as a Source of PeV Gamma-Rays
Samuel T. Spencer, Alison M. W. Mitchell, Brian Reville
Recent results from LHAASO and Tibet AS suggest that the Crab Nebula's gamma-ray spectrum extends to the PeV energy range, however the production mechanisms of this highest ener…
Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array
Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13
Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…
H.E.S.S. realtime follow-ups of IceCube high-energy neutrino alerts
Federica Bradascio, Halim Ashkar, Jowita Borowska +5
The evidence for multi-messenger photon and neutrino emission from the blazar TXS 0506+056 has demonstrated the importance of realtime follow-up of neutrino events by various groun…
The Influence of Satellite Trails on H.E.S.S. Gamma-Ray Astronomical Observations
Samuel T. Spencer, Thomas Lang, Alison M. W. Mitchell
The number of satellites launched into low earth orbit has almost tripled (to over 4000) in the last three years due to the increasing commercialisation of space. Satellite constel…
Long-term multi-band photometric monitoring of Mrk 501
Axel Arbet-Engels, Dominik Baack, Matteo Balbo +18
Radio-to-TeV observations of the bright nearby (z=0.034) blazar Markarian 501 (Mrk 501), performed from December 2012 to April 2018, are used to study the emission mechanisms in it…
Predictions for gamma-rays from clouds associated with supernova remnant PeVatrons
Alison Mitchell, Gavin Rowell, Silvia Celli +1
Interstellar clouds can act as target material for hadronic cosmic rays; gamma-rays produced through inelastic proton-proton collisions and spatially associated with the clouds pro…
Using Muon Rings for the Optical Throughput Calibration of the Cherenkov Telescope Array
Markus Gaug, Stephen Fegan, Alison Mitchell +3
Muon ring images observed with Imaging Atmospheric Cherenkov Telescopes (IACTs) provide a powerful means to calibrate the optical throughput of IACTs and monitor their optical poin…
