Jason's Science Stuff

And this is science???

Some real science....

Poster given at Granada QSO Host Galaxy meeting (1/8/01)
A presentation on results from imaging QSO host galaxies (2/26/01)
A presentation given at the Pasadena AAS in June 2001 on Ultraviolet Imaging of IR-Luminous Merging Galaxies.
Poster given at the Spitzer New Views Meeting, 2004 on IRAC imaging of ULIRGs, including Arp 220. This is a very big jpeg.
Poster given at the 2005 Winter AAS, on mid-IR number counts.

SIRTF/IRAC stuff.

For security reasons, someof the SIRTF pages now require a username and password. This is the same as those used by the SAO web pages.
