Description
I will discuss ultra-high-energy phenomena in microquasars and their
close environments, with a particular focus on compact binaries
characterized by super-Eddington accretion rates. The recent detection
of UHE gamma-ray halos from some of these objects could be a clue for
understanding the origin of galactic cosmic rays in the most problematic
part of the spectrum beyond the "knee" around a few PeV.
