1. 1. 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

3. 2. Foundation for an analysis of the dust of theNearby Universe

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jimmy Kjellqvist; [2021]
   Keywords : Intergalacitc dust; dust distribution; cosmology; cosmological measurements; quasars;

   Abstract : The current cosmological paradigm of an accelerating cosmic expansion issupported by observations of Type Ia supernovae. However, the light emittedby these and other cosmological sources is not only redshifted by cosmicexpansion but will also interact with matter along the light path. READ MORE

4. 3. A Tension between the Early and Late Universe: Could Our Underdense Cosmic Neighbourhood Provide an Explanation?

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Sveva Castello; [2021]
   Keywords : Cosmology; Hubble tension; local void;

   Abstract : In recent years, the increasingly precise constraints on the value of the Hubble constant, H0, have highlighted a discrepancy between the results arising from early-time and late-time measurements. A potential solution to this so-called Hubble tension is the hypothesis that we reside in a cosmic void, i.e. READ MORE

5. 4. Lightcurves of super-Chandrasekhar mass supernovae

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Amanda Byström; [2020]
   Keywords : Type Ia supernovae; lightcurves; Chandrasekhar limit; SN2003fg; Phillip s relationship;

   Abstract : 20 supernovae that spectroscopically match the peculiar, superluminous type Ia supernova 2003fg are studied in this project. SN2003fg is thought to have erupted at a super-Chandrasekhar mass, thus breaching the theoretical mass limit for a white dwarf. READ MORE

6. 5. Properties of Near-Infrared Type Ia Supernovae Light Curves

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Timothy Faerber; [2020]
   Keywords : Supernova; SNe Ia; Cosmology; Photometry; NIR;

   Abstract : As a result of the standardizability of SNe Ia light curves over a wide range of photometric bands, they are used as standard candles to accurately measure distances in the cosmos up to z ≈ 1 [22]. As dust extinction is smaller in the NIR than in the optical [21] there is less dispersion seen in the peak brightnesses of SNe Ia, making them truly standard candles. READ MORE
