Workshop: ''Astrophysics with the CMB-S4 Survey''

April 15 - 16, 2019 | Chicago, University of Chicago

The purpose of the workshop is to bring together leading astronomers and astrophysicists to integrate the planned CMB-S4 Legacy Survey, a multi-band millimeter wave survey covering roughly half the sky at unprecedented sensitivity and observing cadence, with other directions in astrophysics. This includes the time variable sky as seen in solar system science, stellar variability, binary evolution, supernovae, tidal disruption events, and gamma-ray bursts, as well as high-redshift star formation and studies of feedback from black holes and star formation on the intergalactic medium, including galaxy cluster thermodynamics and reionization.

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.
