Relevance of photon-photon dispersion within the jet for blazar axionlike particle searches
James Davies, Manuel Meyer, Garret Cotter
Axionlike particles (ALPs) could mix with photons in the presence of astrophysical magnetic fields. Searching for this effect in gamma-ray observations of blazars has provided some…
Searching for Axion-Like Particles from Core-Collapse Supernovae with Fermi LAT's Low Energy Technique
Milena Crnogorčević, Regina Caputo, Manuel Meyer +2
Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a 10-second long burst of ALPs. These particles sub…
The young massive stellar cluster Westerlund 1 in rays as seen with H.E.S.S
Lars Mohrmann, Andreas Specovius, Romed Rauth +2
Massive stellar clusters have recently been hypothesised as candidates for the acceleration of hadronic cosmic rays up to PeV energies. Previously, the H.E.S.S. Collaboration has r…
Evidence of 100 TeV -ray emission from HESS J1702-420: A new PeVatron candidate
L. Giunti, B. Khelifi, K. Kosack +1
The identification of active PeVatrons, hadronic particle accelerators reaching the knee of the cosmic-ray spectrum (at the energy of few PeV), is crucial to understand the origin…
Detection of extended TeV emission around the Geminga pulsar with H.E.S.S
A. M. W. Mitchell, S. Caroff, J. Hinton +1
Highly extended gamma-ray emission around the Geminga pulsar was discovered by Milagro and verified by HAWC. Despite many observations with Imaging Atmospheric Cherenkov Telescopes…
Detection of new Extreme BL Lac objects with H.E.S.S. and Swift XRT
Mathieu de Bony de Lavergne, Tomas Bylund, Manuel Meyer +2
Extreme high synchrotron peaked blazars (EHBLs) are amongst the most powerful accelerators found in nature. Usually the synchrotron peak frequency of an EHBL is above Hz…
