1. 1. The ultraviolet spectral slope of high-redshift galaxies

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Ludvig Sjöbom; [2016]
   Keywords : galaxies: high-redshift; observational astronomy; ultraviolet: galaxies; galaxies: evolution;

   Abstract : The slope of the ultraviolet continuum emissions from a galaxy between 1250 and 2600 Å provides insights about several facets of the galaxy. Mainly, it is well-correlated with the amount of dust. This work presents a search for objects whose UV-continuum slopes are excessively steep, as well as suggestions for follow-up. READ MORE

3. 2. Channeling of MeV ion beams : Improving sample alignment at the tandem accelerator, Ångström laboratory

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Ludvig Svensson Sjöbom; [2014]
   Keywords : rutherford backscattering; RBS; channelling; tandem; accelerator; thin film;

   Abstract : At the Tandem accelerator in the Ångström laboratory, Uppsala, Rutherford backscattering spectrometry (RBS) is one of the methods used for thin film analysis, providing information on thickness and composition. The films are commonly grown on silicon substrates, whose crystal structure gives rise to channelling effects (a strong angular dependence in the intensity of the signal), which can cause faulty results.
