CMB AND COSMOLOGY

  • Integrated program combines effort at LBNL + UCB
  • Strong program in theory, data analysis, algorithms
  • MAXIPOL, Planck
  • Collaboration with NERSC
  • New instrumentation enables new experiments
  • APEX-SZ, South Pole Telescope
  • Galaxy Cluster Search - probe Dark Energy
  • POLARBEAR design ripe for construction
  • CMB Polarization - probe Energy Scale of Inflation
  • LBNL leads readout development
  • Program combines strengths of National Lab and University
