Cosmology from ground-based CMB experiments: the case of the Atacama Cosmology Telescope
  OKC colloquia

Tuesday 15 May 2018
from 13:15 to 14:15
at FA32
Speaker : Erminia Calabrese (Cardiff)
Abstract : During the last decade high-resolution observations of the Cosmic Microwave Background (CMB) radiation have opened a unique window into the physics of the early Universe. Our best understanding of the cosmological model is currently set by a combination of data from satellite and ground-based experiments, including Planck and the Atacama Cosmology Telescope (ACT). ACT has been observing the microwave sky at multiple frequencies since 2008, constraining cosmology with the CMB temperature damping tail, and providing new information about astrophysical emission contaminating the CMB data. With its second generation of detectors, now sensitive to CMB polarization as well, ACTPol has completed the observing runs and released cosmological results from 2 seasons of data. Over the next five years, the third ACT upgrade, Advanced ACTPol, will continue to scrutinise the sky and prepare the field for the new Simons Observatory due on the sky early 2020s.
