Acceleration and Propagation of Cosmic Rays in High-Metallicity Astrophysical Environments

Abstract

First of all, I would like to express my deepest gratitude to my supervisor, Prof. Dr. Gustavo E. Romero, for his guidance, extensive knowledge, patience, encouraging support, and for trusting in me over all these years. Thank you for the commitment to my Ph.D. project and career and for giving me the freedom to make my own decisions, but always finding time to discuss and advise me.Additionally, I am very grateful to Prof. Dr. Johannes Blümer for reviewing this thesis and especially for allowing me to participate in the Double Doctoral degree in Astrophysics program between the Karlsruhe Institute of Technology (KIT) and the Universidad Nacional de San Martín (UNSAM). I would also like to thank Prof. Dr. Alberto Etchegoyen and Dr. Aníbal Gattone for promoting the Argentinian side of the program. I want to extend my gratitude to all the people and funding organizations (CONICET, CUAA/DAHZ) in both countries, especially to Marie-Christine Mundt and Prof. Dr. Frank Schröder for helping me with all the organizational situations and formalities.My sincerest thanks to Dr. Markus Roth for his encouraging support, especially during my stay in Karlsruhe. Thank you for the patience with my German, for giving me the opportunity to learn how the experimental research on cosmic rays works, and for making me part of the working group, even when I was working on different topics. I am also very grateful to all the people at the IAP (IKP at that time) for the Kaffeepausen, cosmic coffees, movie nights, conferences, and all kinds of scientific and social moments we shared. I want to thank my several office mates there for providing a warm atmosphere, daily fun, and cookies. Particularly many thanks to Sabine Bucher for always taking care of the paperwork, even when I was in Argentina.I also wish to thank the people at ITeDA for always making me feel welcome. Many thanks to my DDAp colleagues from both countries for a good time and for being an extraordinary group of persons always predisposed to help each other. It was a pleasure to share this experience with you.I would also like to thank the kind people at the IAR for the enjoyable environment in such a remote place, especially the people with an own automobile who provided me a safe and comfortable ride. I am also very grateful to the GARRA members for all the scientific exchange and fruitful discussions. Moreover, thanks to the PuMA people for giving me the chance to take part in a brand new project, operating radio telescopes, and teaching me about teamwork. Special thanks to Paula Kornecki, not only for being my office mate at the IAR and collaborator in various projects but principally for being my friend.In the same way, I want to extend my gratitude to all my friends and colleagues in La Plata for organizing not one but two farewell parties for me, one before each travel to Germany, and without whom the daily life would be more exhausting. A special mention to Florencia, Keiko, Carolina, Cecilia, Peco, and Manuela for being there for me, no matter our geographic locatio...
