Her research focuses on understanding the fundemental physics of the universe through measurements of the cosmic microwave background (CMB). In view of the importance of cosmic microwave background radiation to the Big Bang model of the universe (no other model has explained CMB quite so neatly), efforts were redoubled in an attempt to definitively prove the connection, first in the form of the Cosmic Background Explorer (COBE) satellite in 1989, and then the Wilkinson Microwave Anisotropy Probe (WMAP) in 2001. At Argonne National Laboratory, we confront the most pressing questions in science and technology. The CMB holds a remarkable wealth of information about the early Universe. The Cosmic Microwave Background In the past decade, cosmology has undergone a revolution, becoming a precision science. Gamow's research students, Ralph Alpher and Robert Herman, moreover, argued in 1948 that, because the Big Bang effectively happened everywhere simultaneously, that energy should be equally spread as cosmic microwave background radiation (or CMB for short) throughout the universe. Lawrence Berkeley National Laboratory has been selected to serve as the lead laboratory for the DOE roles and responsibilities on CMB-S4, with Argonne National Laboratory, Fermi National Accelerator Laboratory and SLAC National Accelerator Laboratory serving as partner labs and in partnership with universities. A detection of a background of primordial gravitational waves (tensor modes) would push our understanding of fundamental physics into new regimes of time and energy.

Cosmic Microwave Background (CMB) The Cosmic Microwave Background, or CMB, is a faint glow in microwave radiation that is almost perfectly uniform across the sky. Research; Cosmic Microwave Background; CMB. The recent discovery of the previously predicted acoustic peaks in the power spectrum has established a working cosmological model: a critical density universe consisting of mainly dark matter and dark energy, which formed its structure through gravitational instability from quantum fluctuations during an inflationary epoch. For discovering the origins of our universe, Arno Penzias and Robert Wilson won the 1978 Nobel Prize in Physics. In this way we are continually stretching our understanding of the Universe back towards the instance of its beginning. A broad class of inflationary models predicts a ratio of tensor-to-scalar power of r ≳ 0.01.
