1. 1. Simulating the spectra of galaxies in the reionization epoch : Constraining the escape fraction of ionizing photons

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Christian Binggeli; [2015]
   Nyckelord :;

   Sammanfattning : The cosmic reionization represents a fundamental yet poorly understood phase transition in the evolution of our universe. The most promising theory is that the ionizing radiation from young hot stars in star-forming galaxies drove reionization, but much information about the number of galaxies and the escape fraction of ionizing radiation from galaxies is still missing.

3. 2. Stellar libraries for population synthesis : A comparative study of the MARCS and ATLAS9 theoretical stellar libraries

   Kandidat-uppsats, Institutionen för fysik och astronomi

   Författare :Christian Binggeli; [2013]
   Nyckelord :Population synthesis; stellar libraries; MARCS; ATLAS9; model stars;

   Sammanfattning : Stellar population synthesis is a tool for modelling galaxies and their spectral energy distributions. By combining the spectra of every star within a galaxy, it becomes possible to form the spectrum of the galaxy as a whole. LÄS MER
