Looking for Cracks in the Cosmological Model - Dark Matter and CMB Observations

Explore cutting-edge cosmological research in this physics colloquium presented by Princeton University's Jo Dunkley, examining potential inconsistencies in the Lambda-Cold Dark Matter model through recent cosmic microwave background observations. Delve into findings from the Atacama Cosmology Telescope, understanding how scientists use relic CMB light as a cosmic backlight to measure cosmic structures and map dark matter across half the sky. Learn about the current challenges to the standard cosmological model from various astronomical observations, and discover the promising future directions in early universe physics research, including upcoming projects like the Simons Observatory.
