Supernova remnants and γ-ray sources
(Elsevier Science, 2003-08)
A review of the possible relationship between gamma-ray sources and supernova remnants (SNRs) is presented. Particular emphasis is given to the analysis of the observational status of the problem of cosmic ray acceleration ...
High-mass microquasars and low-latitude gamma-ray sources
(EDP Sciences, 2004-12)
Population studies of unidentified EGRET sources suggest that there exist at least three different populations of galactic gamma-ray sources. One of these populations is formed by young objects distributed along the galactic ...
Gravitational microlensing of gamma-ray blazars
(Wiley Blackwell Publishing, Inc, 2003-12)
We present a detailed study of the effects of gravitational microlensing on compact and distant γ -ray blazars. These objects have γ -ray-emitting regions that are small enough to be affected by microlensing effects produced ...
Signatures of hadronic cosmic rays in starbursts? : high-energy photons and neutrinos from NGC 253
(IOP Publishing, 2003-12)
We show that it appears possible for starburst galaxies, like the nearby NGC 253, recently identified as a TeV source by the CANGAROO collaboration, to emit a significant amount of high-energy γ-rays and neutrinos through ...
