Ordinary Meeting: "Skeletons in the cupboard: Galaxies are cannibals!"

Friday 21 September 2012 - 8:00pm
Skeletons in the cupboard: Galaxies are cannibals!
Speaker: Prof Geraint Lewis, University of Sydney
Venue: Epping Creative Centre - 26 Stanley Road, Epping
Abstract: Large galaxies, like our own Milky Way, have a dirty secret; they got to their immense size by tearing apart and consuming their galactic companions. In this talk I will examine the evolution of galaxies over the history of the Universe, showing that such cannibalism is a natural part of galaxies growing up. I will also show that this cannibalism continues to this day, catching both the Milky Way and Andromeda in the act of consuming of little galaxies that have ventured too close.
Biography: Professor Geraint Lewis was born in Old South Wales, and studied Physics at the Universities of London and Cambridge. Since completing his PhD he has worked at the State University of New York, Victoria University in Canada, and the University of Washington in Seattle. He then became a Research Astronomer at the Anglo-Australian Observatory before joining The University of Sydney in 2002 to continue his studies of cosmology and the evolution of the Universe.
