Co-Directors’ Message

As knowledge about the universe grows, the fields of physics and astronomy become more expansive. Even as we gain answers, questions remain about the origins and evolution of the universe and the fundamental theories of matter and energy. The Center for Particle Cosmology brings together theorists and experimentalists in cosmology and particle physics to answer these questions in an environment distinguished by unfettered interactions and collaborations between members of the traditionally distinct groups.

In 1982, while a grad student at Penn, my advisor and I wrote a paper that has since become very famous. We helped to invent a new theory describing the very beginning of the Universe. The resulting “Cosmic Inflation…

New stellar stream, born outside the Milky Way, discovered with machine learning

Finding this new collection of stars, named after Nyx, the Greek goddess of night, was made possible using machine learning tools and simulations of data collected by the Gaia space observatory.
