6. Abstract

We propose to construct high resolution maps of the dark matter distribution in both
HST-GOODS fields. The combination of depth, resolution, field size, and availability
of auxiliary data for the calculation of photometric redshifts make these fields
ideal for the construction of the first high resolution dark matter maps in blank
fields. These maps will be sensitive to dark matter structures with masses greater
than 5x10^13 h^-1 solar masses in the redshift range 0.3<z<0.7, volumes which are
well sampled by public redshift surveys for which ancillary infrared J and K data is
also available. The infrared data, together with the GOODS optical photometry, will
enable us to associate stellar masses with redshift survey galaxies and thereby
correlate maps of the stellar and dark mass distributions on various scales. Such
correlations will provide new and important indications of how galaxies are biased
with respect to the dark matter. The high resolution maps provided by this proposal
will test techniques to be used on future, larger space-based surveys.
