Galactic Clues About the High-Energy Processes in BL Lac (AGN) Jets formed, and how they are related to the central massive black hole (BH) and its accompanying accretion flow. Understanding this coupling, as well as the overall system energetics, is not possible without knowing the jet content (i.e., pure leptonic or hadronic). Unfortunately, this is still a matter of significant debate in the community.

Theory of Cosmic Ray and High-Energy Gamma-Ray Production in Supernova Remnants rays (CRs) originates in supernova remnants (SNRs). Theoretically progress in the solution of this problem has been due to the development of the theory of diffusive shock acceleration (see, for example, reviews [1–3]). Although still incomplete, the theory is able to explain the main characteristi

Electron Acceleration by Quasi-Parallel Shock Wavestabilities induced by protons in the transition region inside the shock plays the main role in the electron heating and their injection to the first order Fermi acceleration mechanism. The electron distribution function in the vicinity of the shock front can be calculated in our model. The model is

Supernovae, Superbubbles, Nonthermal Emission & Light Element Nucleosynthesis in the Galaxy with molecular clouds, superbubbles created by massive starformation regions, and high-velocity clouds. We discuss hard continuum and the 511 keV annihilation line emission from that objects. Multiwavelength spectra of extended and compact sources are used to constrain the nonthermal particle gener

Cosmic Ray Interactions in the Galactic Center RegionIt is usually assumed that these gamma-rays arise from the interactions of cosmic ray nuclei with ambient matter. Cosmic Ray particles have been observed up to 310. eV, with many arguments suggesting, that up to about 3 10. eV they are of Galactic origin. Cosmic ray particles get injected by their s

A New Model for the Thermal X-Ray Composites and the Proton Origin γ-Rays from Supernova Remnantslectrons are accelerated on SNR shocks up to the energy ~ 10. eV. We have no direct observational confirmations about proton acceleration by SNR. Different models of γ-emission from SNRs predict different emission mechanisms as dominating. Only π° decays created in proton-nucleon interactions allow
