6. Interferometric observations of H -absorbing gas in active galaxies
Sammanfattning : .... LÄS MER
7. Galaxies in the epoch of reionization : Investigating the high-redshift galaxy population through simulations and observations
Sammanfattning : The cosmic reionization is the last major gas phase transition in cosmic history, yet it remains poorly understood. Current constraints indicate that early star-forming galaxies drove the reionization process through producing and releasing large numbers of ionizing photons into the intergalactic medium. LÄS MER
8. Star Formation and feedback at key physical scales for galaxy evolution
Sammanfattning : Feedback from young, massive stars plays an essential role in the self-regulation of star formation in galaxies, and in shaping the galaxies' global properties. This phenomenon originates at small scales, surrounding the stars, but has been observed to be effective up to galactic-wide scales. LÄS MER
9. How ISM properties drive Lyman Continuum Escape
Sammanfattning : The thesis introduces physical processes that are at work in astrophysical plasmas and reviews the current state of research related to the emission of ionizing photons, i.e. Lyman continuum (LyC). Star forming galaxies and active galactic nuclei are discussed as sources of LyC. LÄS MER
10. 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
