SLAC-2017 continues a successful series of workshops bringing together the CMB community to plan a coordinated, stage-4 ground-based CMB experiment.

Themes of this workshop include a particular focus on
- Clusters and high-ell science
- Systems engineering and technical flowdown
- Discussion of the structure of a formal CMB-S4 scientific collaboration.Learn more >>

CMB-S4 Science Book, First Edition (arXiv:1610.02743)
October 10, 2016
This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South Pole, the high Chilean Atacama plateau and possibly a northern hemisphere site, all equipped with new superconducting cameras. CMB-S4 will dramatically advance cosmological studies by crossing critical thresholds in the search for the B-mode polarization signature of primordial gravitational waves, in the determination of the number and masses of the neutrinos, in the search for evidence of new light relics, in constraining the nature of dark energy, and in testing general relativity on large scales.Learn more >>

This is the fourth of a series of biannual ''Cosmology with CMB-S4'' workshops dedicated to developing the next generation ground-based Cosmic Microwave Background program, CMB-S4. The first two days of the workshop are dedicated to CMB-S4. The third day will be an overlap day with the ''Futures Cosmic Surveys'', which is being held at Chicago September 21-23.Learn more >>

The 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 second in a series of potentially biannual workshops focused on developing the CMB-S4 project.

This collaboration workshop will be hosted by Lawrence Berkeley National Laboratory.Learn more >>

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.Learn more >>
