“…Starburst galaxies are observed to drive large-scale magnetised outflows which have been proposed as possible sites of UHECR acceleration [472]. No consensus has been reached on this scenario, with some authors concluding that the properties of the wind are not sufficient to accelerate particles to 10 20 eV [473][474][475]. The Auger collaboration has reported the observation of an excess of UHECRs with respect to background expectations from nearby starburst galaxies [39].…”

Pin down the shower energy observable to use μ as a composition-only Reduce hadronic uncertainties interaction model E threshold (TBD) Other messengers Galactic * μ / em separation † * depending on analysis progress † depending on detector configuration• At least one next-generation experiment needs to be able to make high-precision measurements to explore new particle physics and measure particle rigidity on an event-by-event basis. Of the planned next-generation experiments, GCOS is the best positioned to meet this recommendation.• As a complementary effort, experiments with sufficient exposure ( 5 × 10 5 km 2 sr yr) are needed to search for Lorentz-invariance violation (LIV), SHDM, and other BSM physics at the Cosmic and Energy Frontiers, and to identify UHECR sources at the highest energies.• Full-sky coverage with low cross-hemisphere systematic uncertainties is critical for astrophysical studies. To this end, next generation experiments should be space-based or multi-site. Common sites between experiments are encouraged.• Based on the productive results from inter-collaboration and inter-disciplinary work, we recommend the continued progress/formation of joint analyses between experiments and with other intersecting fields of research (e.g., magnetic fields).• The UHECR community should continue its efforts to advance diversity, equity, inclusion, and accessibility. It also needs to take steps to reduce its environmental impacts and improve open access to its data to reduce the scientific gap between countries.vi

“…For NGC 253, both possibilities are ruled out by the observational evidence. Based on simulation studies, larger wind densities of 1.5×10 2 cm −3 , 6.75×10 2 cm −3 , and 10 3 cm −3 were suggested by Anchordoqui & Torres (2020). However, that work does not take any energy or escape loss into account.…”

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...

“…Much has been learned with these ground observatories, but the nature of the astrophysical sources of UHECRs remains a mystery [19][20][21]. Proposed sources include extremely fast-spinning young pulsars [22][23][24], active galactic nuclei (AGN) [25][26][27], starburst galaxies (SBGs) [28][29][30], and gamma-ray bursts (GRBs) [31,32], among others. Some of these models can partially accommodate current Auger and TA observations, but the scarcity of observed events above tens of EeV has hindered a clear identification of the sources.…”

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky. POEMMA will observe the air fluorescence produced by extensive air showers (EASs) from UHECRs and potentially UHE neutrinos above 20 EeV. Additionally, POEMMA has the ability to observe the Cherenkov signal from upward-moving EASs induced by Earth-interacting tau neutrinos above 20 PeV. The POEMMA spacecraft are designed to quickly re-orientate to follow up transient neutrino sources and obtain currently unparalleled neutrino flux sensitivity. Developed as a NASA Astrophysics Probe-class mission, POEMMA consists of two identical satellites flying in loose formation in 525 km altitude orbits. Each POEMMA instrument incorporates a wide field-of-view (45∘) Schmidt telescope with an optical collecting area of over 6 m2. The hybrid focal surface of each telescope includes a fast (1 μs) near-ultraviolet camera for EAS fluorescence observations and an ultrafast (10 ns) optical camera for Cherenkov EAS observations. In a 5-year mission, POEMMA will provide measurements that open new multi-messenger windows onto the most energetic events in the universe, enabling the study of new astrophysics and particle physics at these extreme energies.
