The SPT-3G experiment began its 2020 winter observing season on March 23, 2020. The SPT-3G camera on the South Pole Telescope (SPT) is undertaking a 1500 square degree survey of the cosmic microwave background, the light left over from the Big Bang. SPT is located at the geographic South Pole, and takes some of its… More »
These research organizations — the University of Chicago and the U.S. Department of Energy’s Fermi National Accelerator Laboratory and Argonne National Laboratory — worked together to build a new, ultra-sensitive camera for the telescope, called SPT-3G, which contains 16,000 superconducting detectors. Exploiting the technical capability and expertise of its Silicon Detector Facility, Fermilab led the… More »
The cosmic microwave background is the radiant heat left over from the big bang. It was emitted nearly 14 billion years ago, just 380,000 years after the big bang, and has traveled across literally the entire observable universe. This makes the CMB an ideal backlight to find the most massive, distant structures in the universe,… More »
