The Theory group studies a broad range of problems in astrophysics and cosmology. The group's research involves various physical processes operating in diverse environments and vastly different length scales: in planets, stars, and the interstellar medium; in supernovae and gamma-ray bursts; in galaxies, supermassive black holes, and the intergalactic medium; and in the universe as a whole. The Theory Group's research activities cover all the important epochs and events in the cosmic history, from the Big Bang to the ongoing processes in the solar system.
