Cosmic Ray Diffusion in the Galaxy and Diffuse Gamma by Daniele Gaggero

By Daniele Gaggero

The unique paintings awarded during this thesis constitutes a massive contribution to fashionable Cosmic Ray (CR) physics, and springs in the course of probably the most fascinating sessions of this box.
The first half introduces a brand new numerical code (DRAGON) to version the CR propagation in our Galaxy. The code is then used to accomplish a mixed research of CR information, making it attainable to figure out their propagation houses with extraordinary accuracy.
The moment half is devoted to a theoretical interpretation of the new the most important experimental effects on cosmic electron and positron spectra (PAMELA, Fermi-LAT experiments).  Using the instruments built within the first a part of the thesis, the writer convincingly argues for the life of a brand new spectral part, which can come up both from neighborhood astrophysical assets, resembling pulsars, or from darkish subject annihilation or decay.
This thesis is a hugely complicated paintings; the tools, research and effects are basically and thoroughly offered.  This paintings is determined to turn into a tremendous reference record for any destiny paintings during this area.
