In a new study, UC Davis researchers and their colleagues in the South Pole Telescope (SPT) collaboration used observational data of this first light — collected from the SPT located at the National Science Foundation’s Amundsen-Scott South Pole Station in Antarctica — to explore the theoretical underpinnings of the Lambda-cold dark matter model, the standard cosmological model of the Big Bang.

The Vaida Chair — the first endowed faculty position in the Department of Physics and Astronomy — was established with a $1.5 million estate gift from Michael L. Vaida, Ph.D. ’73, and his wife, Ester Vaida.
