1. 21. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Blahoslav Rataj; [2021]
   Keywords : Physics and Astronomy;

   Abstract : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. READ MORE

3. 22. General Relativity and Dynamical Universes

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Kajsa Fransson; [2021]
   Keywords : cosmology; general relativity; scale factor; friedmann equation;

   Abstract : The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. READ MORE

4. 23. Analyzing the dust of the Nearby Universe

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Jimmy Kjellqvist; [2021]
   Keywords : Intergalactic dust; cosmology; cosmological measurements; quasars; Intergalaktiskt stoft; kosmologi; kosmologiska mätningar; kvasarer;

   Abstract : 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

5. 24. Death's reflection in the water : Mortuary ritual, ancestral worship and the cosmological significance of water on the island of Gotland during the Pitted Ware culture

   University essay from Uppsala universitet/Arkeologi

   Author : Maja Hed; [2021]
   Keywords : ritual; neolithic; grave goods; cosmology; flowing water; divinity; death; Pitted Ware culture; ritual; neolitikum; gravgåvor; kosmologi; rörligt vatten; gudomlighet; död; Gropkeramisk kultur;

   Abstract : The Pitted Ware culture on Gotland presents a multitude of material that allow archeologists to re-construct and visit the socio-economic structure of a middle-neolithic settlement in the Baltic sea. I will be analyzing the archaeological material in accordance to the ocean, and to what we can interpret as ritual and cosmological variables at the site through ritual theory, and with a method of comparative analogy and research.

6. 25. Galaxies as Clocks and the Universal Expansion

   University essay from KTH/Fysik

   Author : Anders Ahlström Kjerrgren; [2021]
   Keywords : cosmology; cosmic chronometers; universal expansion; Hubble parameter; differential ages; galaxy age; relative age; cosmic time; chi-square minimization; monte carlo sampling; gaussian processes; kosmologi; kosmisk kronometer; universums expansion; Hubbleparametern; differentiell ålder; galaxålder; relativ ålder; kosmisk tid; chi-2-minimering; monte carlo-sampling; gaussiska processer;

   Abstract : The Hubble parameter H(z) is a measure of the expansion rate of the universe at redshift z. One method to determine it relies on inferring the slope of the redshift with respect to cosmic time, where galaxy ages can be used as a proxy for the latter. This method is used by Simon et al.
