The energy spectrum of cosmic rays beyond the turn-down around eV as measured with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

We present a measurement of the cosmic-ray spectrum above 100\,PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750~m. An inflection…

LMC N132D: A mature supernova remnant with a power-law gamma-ray spectrum extending beyond 8 TeV

H. E. S. S. Collaboration, :, H. Abdalla +233

We analyzed 252 hours of High Energy Stereoscopic System (H.E.S.S.) observations towards the supernova remnant (SNR) LMC N132D that were accumulated between December 2004 and March…

The ablation of gas clouds by blazar jets and the long-lasting flare in CTA 102

Michael Zacharias, Jonathan Heil, Markus Boettcher +4

Long-lasting, very bright multiwavelength flares of blazar jets are a curious phenomenon. The interaction of a large gas cloud with the jet of a blazar may serve as a reservoir of…

Search for dark matter annihilation signals from unidentified Fermi-LAT objects with H.E.S.S

H. E. S. S. Collaboration, H. Abdallah, F. Aharonian +226

Cosmological -body simulations show that Milky Way-sized galaxies harbor a population of unmerged dark matter subhalos. These subhalos could shine in gamma-rays and be eventuall…

Evidence of 100 TeV -ray emission from HESS J1702-420: A new PeVatron candidate

H. Abdalla, F. Aharonian, F. Ait Benkhali +232

The identification of PeVatrons, hadronic particle accelerators reaching the knee of the cosmic ray spectrum (few eV), is crucial to understand the origin of cosmic rays…

Probing Dark Matter and Fundamental Physics with the Cherenkov Telescope Array

F. Iocco, M. Meyer, M. Doro +71

Astrophysical observations provide strong evidence that more than 80% of all matter in the Universe is in the form of dark matter (DM). Two leading candidates of particles beyond t…
