Ultra-deep Infrared Surveys:
Stepping Stones from the 48-inch to SIRTF

Dr. Eric Tollestrup, CfA


A wealth of information exists well past the limit set by source confusion from faint, unresolved galaxies. With the launch of SIRTF in 2001, we will be able to ultra-deep surveys from 3.5 to 8.0 microns that should set limits on the total amount of light seen from all galaxies at these wavelength and also extend the source galaxy counts down to nJy levels. I will discuss our efforts to set the ground work for the SIRTF surveys with ongoing ground-based surveys currently under way on the the 48-inch telescope.
