1. Colliding Galaxies in a (Nut)Shell
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionenAbstract : 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.

2. Planes of satellite galaxies
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. READ MORE

3. Event Geometry and Anisotropic Flow in Proton-Proton Collisions
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. READ MORE

4. Do variations in the initial mass function affect galaxy evolution?
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : The initial mass function (IMF) describes the stellar mass distribution for a population of stars at birth. This parameter represents a topic of long standing discussion within astronomy due to its apparent insensitive nature to environmental conditions. However, in the last decade, significant evidence suggesting the contrary has been presented. READ MORE

5. Influence of grain growth on the thermal structure of inner protoplanetary discs
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : Protoplanetary discs surround young stars for the first few million years after their formation and they are the birthplaces of planetary systems. The thermal structure of the discs is regulated by their dust content and the opacity that it provides. READ MORE
