Title: Cosmological Results from ACT DR4 CMB Power Spectra
Date: Thu, Aug 06, 2020, 11:00 - 12:00
Place: Zoom
Abstract: The Atacama Cosmology Telescope maps the CMB temperature anisotropy and polarization at arcminute resolution over 17,000 square degrees. I will present the temperature and polarization angular power spectra from 5,400 square degrees of the 2013–2016 survey at 98 and 150 GHz, and the cosmological parameters derived from these power spectra.
