- Special ASTRONOMY TALK
- "The Cosmological Challenges of Dwarf Galaxies"
- Time: 3:45 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.
