1. Defining dark jets at the particle level
Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. LÄS MER
2. Resolving the smallest scale of star formation at Cosmic Noon with JWST : Star-forming clumps in a galaxy lensed by Abell 2744
Master-uppsats, Stockholms universitet/Institutionen för astronomiSammanfattning : At higher redshift galaxies exhibit increasingly irregular and clumpy morphologies, withstar-forming clumps dominating the FUV output of their host galaxies thus being inti-mately related to star formation and the formation and evolution of galaxies. This workexamines star-forming clumps in a remarkable, young spiral galaxy at Cosmic Noon witha redshift ofz= 2. LÄS MER
3. The tangled Warp of the Milky Way
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. LÄS MER
4. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

5. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER
