Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge

A. Acharyya, F. Aharonian, H. Ashkar +130

Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…

Gamma-Ray Constraints on Heavy Axion-Like-Particle Decays from Fermi-LAT and H.E.S.S. Blazar Spectra

A. Acharyya, F. Aharonian, M. Backes +117

The propagation of very-high-energy (VHE; GeV) gamma rays from extragalactic sources is affected by interactions with photons of the extragalactic background light (…

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…

Sensitivity of the Cherenkov Telescope Array to spectral signatures of hadronic PeVatrons with application to Galactic Supernova Remnants

The Cherenkov Telescope Array Consortium, F. Acero, A. Acharyya +356

The local Cosmic Ray (CR) energy spectrum exhibits a spectral softening at energies around 3~PeV. Sources which are capable of accelerating hadrons to such energies are called hadr…

Origin and role of relativistic cosmic particles

A. Araudo, G. Morlino, B. Olmi +121

This white paper briefly summarizes the importance of the study of relativistic cosmic rays, both as a constituent of our Universe, and through their impact on stellar and galactic…

Probing extreme environments with the Cherenkov Telescope Array

C. Boisson, A. M. Brown, A. Burtovoi +127

The physics of the non-thermal Universe provides information on the acceleration mechanisms in extreme environments, such as black holes and relativistic jets, neutron stars, super…
