Argonne-2018: Cosmology with CMB-S4

Argonne-2018: Cosmology with CMB-S4 workshop at the Argonne National Laboratory, March 5-7, 2018

The series of open workshops to define the CMB-S4 project and collaboration continued this March with the successful Cosmology with CMB-S4 workshop at Argonne National Laboratory. Among the important achievements of this workshop was a finalized set of bylaws for the collaboration, to be ratified immediately after the workshop. This milestone will mark the beginning of the official CMB-S4 collaboration.

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.
