1. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model
Master-uppsats, Uppsala universitet/HögenergifysikSammanfattning : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. LÄS MER
2. Complementarity of high energy and high intensity experiments for dark photon benchmarks
Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others.

3. Constraining the age of HD 140283
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : HD 140283, also known as the Methuselah star, is an old, metal-poor star on the subgiant branch.It has been the subject of many studies due to its relatively large apparent brightness, and due to itbeing one of the oldest stars known.

4. Analyzing the dust of the Nearby Universe
Master-uppsats, Uppsala universitet/Observationell astrofysikSammanfattning : 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. LÄS MER
5. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. LÄS MER
