NRAO Colloquium

Date: Fri. 12 Dec, 2014 11:00 am - 12:00 pm
Duration: 1 Hour
Location: NRAO

This week's NRAO/NM Colloquium features Brian Keating of the University of California, San Diego. He will present, "The Discovery of Cosmic Microwave Background B-Mode Polarization." In March 2014, the POLARBEAR telescope reported evidence for B-mode polarization at sub-degree scales produced by gravitational lensing of the CMB's E-mode polarization. Soon after, the BICEP2 telescope, which observed from the South Pole for three seasons (2010–2012), released results showing an excess of CMB B-modes in the degree-scale angular range with greater than 5 sigma significance. Keating will discuss the BICEP2 and POLARBEAR experiments, observations, and data analyses, as well as current and planned efforts to follow up these groundbreaking measurements. Hosted by Chris Hales. 11 a.m. in the Domenici Science Operation Center (NRAO) conference room.
