Supernovae, Superbubbles, Nonthermal Emission & Light Element Nucleosynthesis in the Galaxy

  • Andrei M. Bykov
Part of the NATO Science Series book series (NAII, volume 44)

Abstract

Nonthermal particles acceleration and interactions with interstellar matter are considered with special emphasis on the supernova remnants interacting 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 generation models and hard emission spectra resulting from interactions of energetic particles with interstellar matter. We further show that galactic superbubbles are potentially important sites of light element (e.g. 9Be, 10B) nucleosynthesis as well as extended sources of 7-ray emission. Special attention is paid to the CR-ISM interaction regions that can be observed with INTEGRAL and GLAST.
