Description
We present the results from a survey for extremely red objects (EROs) in deep, high-resolution optical images taken from the Hubble Space Telescope (HST) Medium Deep Survey. We have surveyed 35 deep F814W HST/WFPC2 fields in the near-infrared to a typical depth of K>20. From a total area of 206 arcmin^2^ and to a limit of K=20.0, we identify 224 EROs [(1.14+/-0.08)arcmin^-2^] with (I_814_-K)>=4.0 and 83 [(0.41+/-0.05)arcmin^-2^] with (I_814_-K)>=5.0.
