Strong constraint on hadronic models of blazar activity from Fermi and IceCube stacking analysis
A. Neronov, D. V. Semikoz, K. Ptitsyna
High-energy emission from blazars is produced by electrons which are either accelerated directly (the assumption of leptonic models of blazar activity) or produced in interactions…

Particle acceleration in the vacuum gaps in black hole magnetospheres
K. Ptitsyna, A. Neronov
We consider particle acceleration in vacuum gaps in magnetospheres of black holes powered through Blandford-Znajek mechanism and embedded into radiatively-inefficient accretion flo…

Towards a model of population of astrophysical sources of ultra-high-energy cosmic rays
O. E. Kalashev, K. V. Ptitsyna, S. V. Troitsky
We construct and discuss a toy model of the population of numerous non-identical extragalactic sources of ultra-high-energy cosmic rays. In the model, cosmic-ray particles are acce…
