John E. Carlstrom, Chair and the Subramanyan Chandrasekhar Distinguished Service Professor of Astronomy & Astrophysics, is a leading figure in the study of the cosmic microwave background—the light left over from the first few moments of the universe, has been named a 2020 AAAS Fellow.
He has led two international experiments at the South Pole to map the cosmic microwave background; the Degree Angular Scale Interferometer from 1999-2003, and the South Pole Telescope, which is ongoing.
He was named for “distinguished contributions to studies of the Cosmic Microwave Background at millimeter/sub-millimeter wavelengths and for leadership in the associated technical development projects.”
