Measuring parameters of AGN central engines with very high energy gamma-ray flares
A. Neronov, D. Semikoz, S. Sibiryakov
We discuss a "compact source" model of very high energy (VHE) emission from blazars in which the variability time is determined by the blazar central engine. In this model electron…

The GZK horizon and constraints on the cosmic ray source spectrum from observations in the GZK regime
M. Kachelriess, E. Parizot, D. V. Semikoz
We discuss the GZK horizon of protons and present a method to constrain the injection spectrum of ultrahigh energy cosmic rays (UHECRs) from supposedly identified extragalactic sou…
