Science Prizes for the 21st Century - The Kavli Prizes recognize scientists for their seminal advances in three research areas: astrophysics, nanoscience and neuroscience. [more]
Neutrinos produced in the very early Universe decoupled from the primordial plasma when the Universe was less than one second old and temperatures had dropped to of order a few MeV. The Universe today is bathed in a sea of these ancient neutrinos that is known as the cosmic neutrino background (CNB). Recent work by KICP senior member Scott Dodelson and Mika Vesterinen has shed new light on the distance to the surface of last scattering for CNB neutrinos - the distance they have traveled over the past 13.7 billion years. Dodelson and Vesterinen find that the last scattering surface (LSS) of the cosmic neutrino background is much broader and much closer than that of the cosmic microwave background. [more]
