1. 1. Galaxies in the epoch of reionization : Investigating the high-redshift galaxy population through simulations and observations

   Författare :Christian Binggeli; Erik Zackrisson; Sofia Ramstedt; Martin Sahlén; Stephen Wilkins; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; galaxies: high-redshift; galaxies: ISM; galaxies: evolution; reionization; Lyman continuum; Astronomy; Astronomi;

   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

4. 3. On the emergent structures at cosmic dawn

   Författare :Anton Vikaeus; Erik Zackrisson; Martin Sahlén; Andrea Pallottini; Uppsala universitet; []
   Nyckelord :Extragalactic astronomy and cosmology; structure formation; the first generation of stars and galaxies; gravitational lensing.; Astronomi med inriktning mot astrofysik; Astronomy with specialization in Astrophysics;

   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
