DESCRIPTION:General Physics Colloquium\, Professor Jeff McMahon\, Universit
 y of Michigan\n\nRefreshments from 3:30-3:50 pm\n\nTitle:  Mapping New Phy
 sics with the Cosmic Microwave Background\n\nHost:  Mike Niemack\n\nAbstra
 ct:  Measurements of the cosmic microwave background (CMB) are a powerful 
 tool for furthering our understanding of the origin\, contents\, and evolu
 tion of our Universe.  Upcoming measurements will improve our understandin
 g of a number of important questions including the nature of inflation\, d
 ark energy\, and  neutrino masses\; and will enable searches for potential
  surprises including additional light relativistic species. In this talk I
  present the status and plans for measurements of the CMB using ongoing ex
 periments (ACTPol and Advanced ACTPol)\, upcoming experiments (Simons Obse
 rvatory)\, and a future experiment (CMB-S4).  I will describe the technolo
 gical advances that underlie the rapid progress in CMB observations includ
 ing: polarization sensitive detectors which simultaneously observe in mult
 iple colors\; metamaterial antireflection coated lenses and polarization m
 odulators\; and overall advances in experimental design.  I will conclude 
 with forecasts for the science we expect from the CMB in the coming decade
 .
