Unveiling the Nature of Dark Matter with Small-Scale Cosmic Structure

Explore a fascinating astro seminar where Stanford University's Risa Wechsler delves into how small-scale cosmic structures help reveal dark matter's mysterious nature. Learn how dwarf galaxies, gravitational lenses, and stellar streams provide crucial insights into dark matter's microphysical properties despite its elusive nature. Discover how upcoming large photometric and spectroscopic surveys will complement existing dark matter research methods and potentially detect truly dark halos below galaxy formation thresholds, potentially confirming or challenging key predictions of our standard cosmological model. This hour-long presentation examines the frontier of dark matter research through the lens of cosmic structure, offering a comprehensive look at how astronomers are mapping dark matter across the cosmos while seeking to understand its fundamental properties.
