Search for astrophysical PeV gamma rays from point sources with Carpet-2
D. D. Dzhappuev, I. M. Dzaparova, E. A. Gorbacheva +14
Early results of the search for E_γ>1 PeV cosmic photons from point sources with the data of Carpet-2, an air-shower array equipped with a 175 m^2 muon detector, are presented. The…
Carpet-2 search for PeV gamma rays associated with IceCube high-energy neutrino events
D. D. Dzhappuev, I. M. Dzaparova, E. A. Gorbacheva +14
Carpet-2 is an air-shower array at Baksan Valley, Russia, equipped with a large-area (175 m^2) muon detector, which makes it possible to separate primary photons from hadrons. We r…
Towards a medium-scale axion helioscope and haloscope
V. Anastassopoulos, F. Avignone, A. Bykov +32
We discuss the physics case for and the concept of a medium-scale axion helioscope with sensitivities in the axion-photon coupling a few times better than CERN Axion Solar Telescop…
Physical conditions in potential sources of ultra-high-energy cosmic rays: Updated Hillas plot and radiation-loss constraints
Ksenia Ptitsyna, Sergey Troitsky
We review basic constraints on the acceleration of ultra-high-energy (UHE) cosmic rays (CRs) in astrophysical sources, namely the geometrical (Hillas) criterion and restrictions fr…
