Identification and Morphologies of Galaxies with Old Stellar Populations at z̃2.5

2007 
We describe a study of morphologies of galaxies with old stellar populations in radio-source fields at z ~ 2.5. A significant fraction of these are dominated by disks of old stars, and none we have found so far has the properties of present-epoch ellipticals. Recent Spitzer IRAC data confirms that at least one of our prime examples is definitely not a reddened star-forming galaxy.
