1. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : 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.

2. Searching for direct collapse black holes using the James Webb Space Telescope
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Recent detections of massive quasars at z > 6 has proven to be an interesting challengefor cosmology given the short time frame that these objects have to reach a certainmass via conventional methods (e.g., galaxy mergers).

3. Fermi-LAT gamma-ray and multi-wavelength SED analysis and modelling of PKS 0426-380 : A thesis analysing the behaviour and properties of the blazar PKS 0426-380
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. READ MORE

4. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE

5. Analyzing the dust of the Nearby Universe
University essay from Uppsala universitet/Observationell astrofysikAbstract : The aim of this master thesis is to investigate the influence of intergalactic duston astronomical observations. The current cosmological paradigm of an acceleratingcosmic expansion is supported by observations of Type Ia supernovae. READ MORE
