1. 1. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Þóra Karlsdóttir; [2023]
   Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

   Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

3. 2. Dynamic Capabilities in Digital Transformation How to be Successful in Digital Transformation

   University essay from Göteborgs universitet/Graduate School

   Author : Jacob Wadsjö; Oliver Örskov Praetorius; [2022-08-19]
   Keywords : Dynamic Capabilities; Digital Transformation; Simulation Technology; Digitalisation of R D; Innovation Management;

   Abstract : Although firms on a large scale seemingly have realised the importance of becoming more digital in order to stay relevant in the future, organisations struggle to implement and scale digital initiatives outside isolated functions. This highlights the strategic and organisational hardships of transformation efforts. READ MORE

4. 3. 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.

5. 4. Planes of satellite galaxies

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Jessica Laura Erika Kocher; [2022]
   Keywords : Physics and Astronomy;

   Abstract : 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

6. 5. Stellar Encounters at the Galactic Centre

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Roberts Fisers; [2022]
   Keywords : Galaxy; encounter; SPH; NSC; Physics and Astronomy;

   Abstract : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. READ MORE
