1. 1. Analyzing the dust of the Nearby Universe

   Master-uppsats, Uppsala universitet/Observationell astrofysik

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

   Sammanfattning : 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

3. 2. An Infrared Stellar Thermometer

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Ieva Puspure; [2021]
   Nyckelord :Infrared Spectroscopy; Infrared; Red giants; Stellar Temperature; Spectroscopy; Physics and Astronomy;

   Sammanfattning : Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researched.
