Physics Colloquium




Low-mass galaxies provide an essential testing ground for theoretical predictions of cosmology. Their number densities, structures, and internal dynamics provide some of the most interesting clues to the nature of dark matter and the theory of galaxy formation on small scales. Recent advances in telescope instrumentation and image analysis techniques have enabled comprehensive investigations of such low surface brightness galaxies. I will present results from novel observations of low-mass galaxies beyond our local galactic neighborhood, uncovering their significant diverseness and new astrophysical puzzles. I will discuss some of the follow-up observations of these extragalactic low-mass galaxies, focusing on their dark matter content and intriguing globular cluster populations. I will conclude by briefly discussing ongoing and future surveys that collectively have the potential to unveil the physics of dark matter.
