CMB Lensing Measurements: Mapping Dark Matter with ACT and ACTPol

Seminar | September 25 | 1:10 p.m. | B1 Hearst Field Annex

Speaker/Performer: Blake Sherwin, Princeton

Sponsor: Department of Astronomy

Measurements of lensing in the cosmic microwave background (CMB) directly probe the projected distribution of dark matter out to high redshifts. I will describe the first detection of the power spectrum of CMB lensing with the Atacama Cosmology Telescope (ACT) and its cosmological implications, and will show results from cross-correlations of ACT CMB lensing maps with quasars, galaxies and other...   More >
