UMICH-2015: Cosmology with CMB-S4 workshop at the University of Michigan September 21-22, 2015

This workshop aims to further develop the science goals, including the requisite measurements to achieve them, for the next generation ground-based Cosmic Microwave Background program, CMB-S4. The output of the workshop will be a working draft of the CMB-S4 ''Science Book.'' This is the first in a series of potentially biannual workshops focused on developing the CMB-S4 project.

Opening sessions will begin with invited plenary talks. These will be followed by a series of parallel breakout sessions, followed by plenary reports and discussion.

Current status of CMB-S4CMB-S4: Next Generation CMB Experiment

The 'Stage-4' ground-based cosmic microwave background (CMB) experiment, CMB-S4, consisting of dedicated telescopes equipped with highly sensitive superconducting cameras operating at the South Pole, the high Chilean Atacama plateau, and possibly northern hemisphere sites, will provide a dramatic leap forward in our understanding of the fundamental nature of space and time and the evolution of the Universe. CMB-S4 will be designed to cross critical thresholds in testing inflation, determining the number and masses of the neutrinos, constraining possible new light relic particles, providing precise constraints on the nature of dark energy, and testing general relativity on large scales.
