Abstract:
Interpreting surveys of galaxies which span a range of redshifts
requires being able to interpret broad-band observations of galaxies
taken through different effective rest-frame bandpasses.  All claims
of evolution of the galaxy population rely on accurate K-corrections
in order to do this.  The PI has written widely used software (over
100  registered users and over 100  citations in the literature) for
calculating K-corrections in the UV, optical and near-infrared, and
proposes to extend this software to self-consistently include the mid
and far-infrared.  Large public Spitzer surveys like the First Look
Survey and SWIRE overlap deep (to redshift unity) public redshift
catalogs, and provide an excellent basis for developing these tools.
This proposal outlines a plan for developing and testing an
appropriate set of templates for fitting SEDs and calculating
K-corrections.  The tools (in addition to furthering the PI's own work
on galaxy evolution) will be publicly released.
