16. H2S and dense gas in luminous infrared galaxies and their outflows
Sammanfattning : Luminous infrared galaxies (LIRGs) are dusty galaxies that are going through an important and likely transient phase in their evolution. They experience rapid growth through bursts of star formation or an accreting supermassive black hole, an Active Galactic Nucleus (AGN). LÄS MER
17. Supernova surroundings on circumstellar and galactic scales
Sammanfattning : Some stars cease to be in a bright and destructive display called a supernova. This thesis explores what we can learn about supernovae (SNe) by studying their immediate surroundings, and what the SNe can teach us about their environments. LÄS MER
18. On the emergent structures at cosmic dawn
Sammanfattning : Recent developments have granted us the means necessary for studying the emergence of the very first luminous structures in the Universe. The beckoning of the first generation of stars marks the end of the cosmic dark ages – thus entering into the cosmic dawn. LÄS MER
19. An ALMA perspective on high-redshift galaxy evolution
Sammanfattning : The processes governing the growth and evolution of high-redshift massive galaxies have long been a subject of intense investigations. Studies of the cosmic star-formation rate density have shown a peak at z ∼ 2 − 3, demonstrating the distinct need to understand the mechanisms by which galaxies acquired the fuel necessary to ignite such intense star formation.

20. Investigating the potential of current and future neutrino detectors to identify the sources of the astrophysical neutrinos seen by IceCube
Sammanfattning : High energy neutrino astronomy aims to view the universe with a new messenger, the neutrino. This messenger provides another window onto the universe, complementing what we can learn from photons, cosmic rays, and gravitational waves. LÄS MER
