1. 1. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Olof Nebrin; [2022]
   Keywords : Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

   Abstract : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. READ MORE

3. 2. Colliding Galaxies in a (Nut)Shell

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Jonathan Petersson; [2022]
   Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

   Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

4. 3. Galaxy evolution in extreme environments

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Samhitha Vadlamani; [2019]
   Keywords : Galaxy evolution; interactions; starburst; Compact galaxy groups; Stephan s Quintet; Physics and Astronomy;

   Abstract : Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us to capture signatures of these interactions (e.
