Abstract:
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 arcmin2 and to a limit of K=20.0, we
identify 224 EROs [(1.14±0.08)arcmin-2] with (I814-K)≥4.0
and 83 [(0.41±0.05)arcmin-2] with (I814-K)≥5.0.
Description:
NIR imaging was obtained using the Isaac Newton Group Red Imaging
Device on the 4.2-m William Herschel Telescope (WHT). Observations
were made over 12 nights; 2000 November 13-15, 2000 December 9-11 and
2001 May 1-6.
