1. 6. Finding stars that are likely to be from accreted satellite galaxies

   Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Helena Cronstedt; [2023]
   Nyckelord :galaxy mergers; merger debris; velocity space; Physics and Astronomy;

   Sammanfattning : The Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. LÄS MER

3. 7. Black Hole Dynamics in Stellar Clusters

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Markus Strickert; [2022]
   Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

4. 8. Energilösningar för en energismart stadsdel

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Pontus Dahl; Nicholas Näslund Sandmark; [2021]
   Nyckelord :Energismarta städer; netto-noll energianvändning; energilösningar; solceller; PV; solfångare; PT; solhybrider; PVT; geoenergisystem; bergvärme; borrhålslager; värmepump; Polysun; EED; Technology and Engineering;

   Sammanfattning : The aim of this master thesis is to conclude how the energy systems of smart cities can be designed to achieve an annual net-zero energy consumption. The study investigated different techniques that can be used for producing and storing energy locally. This was implemented on a planned residential project located in Veberöd, south of Scania.

5. 9. High resolution imaging observations of exoplanet host stars

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Kaltrina Kajtazi; [2020]
   Nyckelord :Speckle imaging; Speckle interferometry; High resolution imaging; Short integration time; Binaries; Exoplant hosts; Stellar properties; WIYN; Gemini; Orbital period; Physical separation; Angular separation; magnitude difference; Physics and Astronomy;

   Sammanfattning : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. LÄS MER

7. 10. The astronomical consequences of primordial black holes

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Loke Lönnblad Ohlin; [2019]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : In the radiation or early matter dominated eras of the Universe, there is a theoretical possibility for the formation of black holes (BHs). These primordial black holes (PBHs) have been thought of as a possible candidate for dark matter (DM), and an attractive one at that as it would explain DM using only baryonic physics. LÄS MER
