SUMMARY:CMB Observations for Large-Scale Structure - James Bartlett (APC)

DESCRIPTION:Apart from telling us about the early universe\, observations 
 of the cosmic microwave background (CMB) are proving to be a powerful prob
 e of large-scale structure and its evolution\, offering the opportunity to
  answer some key questions in both cosmology and galaxy formation.  These 
 studies\, started with recent experiments\, have become central elements o
 f the science case for future CMB surveys.  We will focus on two areas: Th
 e new technique of using CMB lensing to measure object masses\, looking in
  particular at calibration of the galaxy cluster mass scale\, and observin
 g the circumgalactic medium (CGM) with the Sunyaev-Zeldovich (SZ) effect. 
  The former technique has implications for constraints from cluster cosmol
 ogy and will provide a view of the light-dark matter connection.  The SZ e
 ffect gives us a powerful new tool for probing the distribution of the CGM
 .  This elusive gas phase contains at least 90% of the baryons today\, but
  remains very difficult observe\, leaving us in the dark concerning a key 
 element of galaxy formation and baryonic history.  \n
