Abstract [en]

The Mini-EUSO instrument is a UV telescope to be placed inside the International Space Station (ISS), looking down on the Earth from a nadir-facing window in the Russian Zvezda module. Mini-EUSO will map the earth in the UV range (300-400. nm) with a spatial resolution of 6.11. km and a temporal resolution of 2.5. μs, offering the opportunity to study a variety of atmospheric events such as transient luminous events (TLEs) and meteors, as well as searching for strange quark matter and bioluminescence. Furthermore, Mini-EUSO will be used to detect space debris to verify the possibility of using a EUSO-class telescope in combination with a high energy laser for space debris remediation. The high-resolution mapping of the UV emissions from Earth orbit allows Mini-EUSO to serve as a pathfinder for the study of Extreme Energy Cosmic Rays (EECRs) from space by the JEM-EUSO collaboration.

Abstract [en]

Ultra-high-energy cosmic rays (UHECRs) are charged particles that have been accelerated to extreme energies, such that they are effectively travelling at the speed of light. Interactions of these particles with the Earth’s atmosphere lead to the development of extensive showers of particles and radiation that can be measured with existing technology. Despite decades of research, the origins of UHECRs remain mysterious. However, they are thought to be accelerated within powerful astrophysical sources that lie beyond the borders of our Galaxy. This thesis explores different ideas towards the common goal of reaching a deeper understanding of UHECR phenomenology. Part I concerns the development of a novel space-based observatory that has the potential to detect unprecedented numbers of these enigmatic particles. The feasibility of such a project is demonstrated by the results from the Mini-EUSO instrument, a small ultraviolet telescope that is currently on-board the International Space Station. In Part II, the focus is on fully exploiting the available information with advanced analysis techniques to close the gap between theory and data. UHECRs are closely connected to the production of neutrinos and gamma rays, so frameworks for the joint analysis of these complementary cosmic messengers are also developed. The results presented herein demonstrate that to progress, it is crucial to invest in the development of both detection and analysis techniques. By taking a closer look at the existing data, new clues can be revealed to reach a more comprehensive understanding and better inform the design of future experiments. 

Abstract [sv]

Ultrahög energetisk kosmisk strålning (UHECR) är laddade partiklar som har accelererats till extrema energier, så att de i praktiken färdas med ljusets hastighet. Det är möjligt att upptäcka dessa partiklar när de växelverkar med jordens atmosfär då omfattande skurar med partiklar och strålning utvecklas, vilka kan mätas med befintlig teknik. Trots decennier av forskning förblir UHECR:s ursprung dold. Men de tros vara accelererade inom kraftfulla astrofysiska källor som ligger utanför vår galax. Denna avhandling utforskar olika idéer med det gemensamma målet att nå en djupare förståelse av UHECR-fenomenologin. Del I handlar om utvecklingen av ett nytt rymdbaserat observatorium som har potential att upptäcka ett stort antal av dessa gåtfulla partiklar. Genomförandet av ett sådant projekt demonstreras av resultaten från Mini-EUSO-instrumentet som för närvarande är ombord på den Internationella rymdstationen. I Del II ligger fokus på att utnyttja tillgänglig information med avancerade analystekniker för att minska klyftan mellan teori och data, för att nå en djupare förståelse av aktuella observationer. UHECR:er är nära kopplade till produktionen av neutriner och gammastrålning. Ramar för gemensam analys av dessa komplementära kosmiska budbärare utvecklas. Resultaten som presenteras här visar att det är avgörande att investera i utvecklingen av både detekterings- och analystekniker för att gå vidare. Genom att titta närmare på befintliga data kan nya ledtrådar avslöjas i sammanhanget med så kallade multi-budbärare och ger information för att bättre utforma framtida experiment.
