Series: Astronomy Colloquium
Date: Wednesday 28-Oct-2020

Location: Online Zoom Only: Contact Benedikt Diemer for URL
Speaker: Prof. Joanna Dunkley (Princeton University)
Title: "The Millimeter Sky from the Atacama Cosmology Telescope"
I will show new maps of the Cosmic Microwave Background made by the Atacama Cosmology Telescope, and describe how they are advancing our knowledge of cosmology and complementing optical large-scale structure surveys. I will show how the new data let us weigh in on the LCDM cosmological model, the Hubble constant and the spatial geometry of the universe, as well as providing a sample of thousands of galaxy clusters, and revealing the distribution of gas around groups of galaxies. These new arcminute-resoution millimeter maps of the sky, and future refinements with upcoming observations, promise to teach us not only cosmology but also about Galactic science, active galactic nuclei and dusty high-redshift galaxies.
Colloquia for the Fall 2020 semester will be held on zoom. Contact Prof. Alberto Bolatto for details.
