An Archaeological Road Trip with the Keck Telescopes
The Keck telescopes have gone on an archaeological road trip to the most remote neighborhoods of our Galaxy. These neighborhoods are peppered with mini-galaxies-within-a-Galaxy that are sparsely populated with just handfuls of stars. Although these galaxies used to harbor supernovae that produced of most of the elements in the periodic table, those factories were shuttered long ago. Keck uncovers the history of these ghost towns--and their defunct manufacturing economies--by discovering what the few surviving stars are made of.
Evan Kirby received his bachelor's degree in physics from Stanford University in 2004 and his Ph.D. from UC Santa Cruz in 2009. He was a Hubble Fellow at Caltech and a Center for Galaxy Evolution Fellow at UC Irvine. As of August 2014, Professor Kirby is an assistant professor in the Department of Astronomy & Astrophysics at Caltech. His expertise is the origin and evolution of the elements of the periodic table in our Galaxy and in other galaxies. He also specializes in the study of very small galaxies and their relation to dark matter and the creation of the elements.
