Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…

The unidentified TeV source HESS J1702-420 has recently been proposed as a new hadronic PeVatron candidate, based on the discovery of a small-scale emission sub-region with extreme…
Search for new cosmic-ray acceleration sites within the 4FGL catalog Galactic plane sources
LAT Collaboration, S. Abdollahi, F. Acero +117
Cosmic rays are mostly composed of protons accelerated to relativistic speeds. When those protons encounter interstellar material, they produce neutral pions which in turn decay in…
Characterization of the GeV emission from the Kepler supernova remnant
Fabio Acero, Marianne Lemoine-Goumard, Jean Ballet
The Kepler supernova remnant (SNR) is the only historic supernova remnant lacking a detection at GeV and TeV energies which probe particle acceleration. A recent analysis of Fermi-…
Possible Detection of X-Ray Emitting Circumstellar Material in the Synchrotron-Dominated Supernova Remnant RX J 1713.7-3946

We report on a discovery of an X-ray emitting circumstellar material knot inside the synchrotron dominant supernova remnant (SNR) RX J1713.7-3946. This knot was previously thought…
Multiple accelerated particle populations in the Cygnus Loop with Fermi-LAT
A. Tutone, J. Ballet, F. Acero +2
The Cygnus Loop (G74.0-8.5) is a very well-known nearby supernova remnant (SNR) in our Galaxy. Thanks to its large size, brightness, and angular offset from the Galactic plane, it…
Evidence of 100 TeV -ray emission from HESS J1702-420: A new PeVatron candidate
