Sargent Wallace Leslie William Sargent 15 February 1935 1994 Bruce Medalist Wal Sargent was the first person from his high school to attend a university . He studied fluid mechanics at the University of Manchester but with an eye toward applying it to theoretical problems in astrophysics . He has spent nearly all of his career at the California Institute of Technology where he has become a spectroscopist , observing peculiar stars , stars in the galactic halo , and peculiar galaxies and quasars . He is particularly renowned for investigations of quasar absorption lines which he now does with the Keck Magellan Chandra and Hubble Space Telescope s . He and his colleagues have contributed greatly to our knowledge of the intergalactic medium .

Bowen Professor of Astronomy Caltech 249-17 Pasadena , CA 91125 374 Cahill Center phone : 626-395-4055 e-mail : wws at astro.caltech.edu The 200 inch Hale Telescope at the Palomar . Observatory Current Research Interests : One main aim is to study the evolution of large scale structure and the physics of the intergalactic medium at an epoch when the first stars and galaxies are forming and the baryons in the universe are largely in the form of hydrogen and helium gas . My main collaborators are Michael Rauch OCIW George Becker Kavli Institute , Cambridge and Bryan Penprase Pomona College Most of our work involves observations of Quasar Absorption Lines using the spectrographs on the two 10 meter Keck Telescopes in Hawaii and the 6.5 meter Magellan Telescopes at

We have participated frequently in the past , but this year we didn’t quite get our act together . But it doesn’t matter who sets up the donors page , there are many great programs out there looking for . support So instead , this year we’re pointing people to Aatish Bhatia’s donor
One of the lowest mass supermassive black holes ever observed in the middle of a galaxy has been identified, thanks to NASA's Chandra X-ray Observatory and several other observatories.

This gallery shows four planetary nebulas from the first systematic survey of such objects in the solar neighborhood made with NASA's Chandra X-ray Observatory.
Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years.
