Lick Observatory Music of the Spheres Lecture and Music Series - SOLD OUT

Speaker: Dr. Michael Gregg is a Research Astrophysicist in the Department of Physics at the University of California, Davis, but he spends most of his professional time at the Institute for Geophysics and Planetary Physics at the Lawrence Livermore National Laboratory. Michael started his career investigating the stellar population of relatively nearby S0 galaxies, showing that they may have evolved from spiral galaxies. This work spawned investigations of nearby galaxy clusters.

His collaboration with Michael Drinkwater (U.Queensland) on the Fornax and Virgo clusters has discovered "ultra-compact dwarfs'' the first new type of galaxy to be discovered since Edwin Hubble laid out the original galaxy classification scheme in the 1930's. With Michael West (U. Hawaii, Hilo), he is studying the remains of recently destroyed galaxies in the Coma and Centaurus clusters. Much of this nearby galaxy work is done using the Hubble Space Telescope. At the other end of the Universe, Michael searches for gravitationally lensed quasars and more exotic types of quasars nearly buried by dust or having unusual radio-emitting properties.
