The starburst galaxy NGC 253 revisited by H.E.S.S. and Fermi-LAT
Context. NGC 253 is one of only two starburst galaxies found to emit γ-rays from hundreds of MeV to multi-TeV energies. Accurate measurements of the very-high-energy (VHE; E > 100 GeV) and

Abstract Several observations are revealing the widespread occurrence of mildly relativistic wide-angle AGN winds strongly interacting with the gas of their host galaxy. Such winds are potential
Constraints on Gamma-Ray and Neutrino Emission from NGC 1068 with the MAGIC Telescopes
Starburst galaxies and star-forming active galactic nuclei (AGN) are among the candidate sources thought to contribute appreciably to the extragalactic gamma-ray and neutrino backgrounds. NGC 1068 is
The diffuse gamma-ray flux associated with sub-PeV/PeV neutrinos from starburst galaxies
One attractive scenario for the excess of sub-PeV/PeV neutrinos recently reported by IceCube is that they are produced by cosmic rays in starburst galaxies colliding with the dense interstellar
Prospects for very high energy observations of Starburst/Seyfert galaxies
A handful of non-blazar galaxies, including both Seyfert and starburst galaxies, have been observed to emit gamma-rays by the Fermi Gamma-ray Space Telescope. For one of these objects, NGC 1068, a

We construct a family of models for the evolution of energetic particles in the starburst galaxy M82 and compare them to observations to test the calorimeter assumption that all cosmic ray energy is
Upper limits on the VHE γ-ray flux from the ULIRG Arp 220 and other galaxies with VERITAS
The cores of ultra-luminous infrared galaxies (ULIRGs) are very dense environments, with a high rate of star formation and supernova explosions. They are thought to be sites of cosmicray
DIFFUSE HARD X-RAY EMISSION IN STARBURST GALAXIES AS SYNCHROTRON FROM VERY HIGH ENERGY ELECTRONS
The origin of the diffuse hard X-ray (2-10?keV) emission from starburst galaxies is a long-standing problem. We suggest that synchrotron emission of 10-100?TeV electrons and positrons (e ?) can
Highlights of Gamma-ray astronomy with imaging air Cherenkov telescopes
The observation of gamma-ray sources at energies between tens of GeV and tens of TeV has been driven by ground-based Cherenkov telescopes. The observational techniques and methods employed have been
