The Cosmological Challenges of Dwarf Galaxies
Time: 3:45 pm - 5:00 pm
Place: 4421 Sterling Hall
Speaker: Julio Navarro, University of Victoria
Abstract: A prime challenge to our understanding of galaxy formation concerns the scarcity of dwarf galaxies compared with the numerous low-mass halos expected in the current LCDM paradigm. This is usually accounted for by assuming that energetic feedback from evolving stars confines dwarf galaxy formation to relatively massive halos spanning a narrow mass range. I will highlight a number of observations that may be used to test this assumption and discuss the puzzles and challenges that arise from this analysis.
Host: Prof Elena D'onghia
