Baryonic Solutions and Challenges to Cosmological Models of Dwarf Galaxies

Explore the complexities of dwarf galaxies and their role in testing the Lambda Cold Dark Matter (LCDM) model in this comprehensive lecture from the Simons Foundation. Delve into key challenges facing theoretical models and observational data, including stellar mass to halo mass relationships, dark matter cores, dwarf galaxy morphology, and rotation curve diversity. Learn how baryonic physics modeling in galaxy formation simulations helps bridge the gap between theoretical predictions and real-world observations. Discover emerging observational opportunities for testing the LCDM model, focusing on ultrafaint galaxies beyond the Milky Way, phase-space analysis of stars in nearby cored dwarfs, and star formation patterns in low-mass galaxies. Gain insights into cutting-edge astronomical research that continues to shape our understanding of cosmological models and galaxy formation.
