Explore a one-hour lecture that delves into the fascinating world of Ultra Diffuse Galaxies (UDGs) and their impact on our understanding of galaxy formation. Learn about these unique celestial objects that possess the physical dimensions of giant galaxies but emit light at the level of dwarf galaxies. Discover the three distinct categories of UDGs: the "puffed-up" dwarf galaxies formed through known processes, the mysterious "Failed Giants" with rich globular cluster systems and massive dark matter halos that defy current simulations, and the intriguing dark matter-deficient UDGs. Examine observational findings about UDGs and their globular cluster systems, while exploring various formation theories and pathways. Gain insights into why some UDGs formed stars and star clusters early in their existence but mysteriously ceased star formation, and understand recent developments in explaining dark matter-free UDGs that challenge conventional galaxy formation models.
