The Hubble Deep Field South -- Project Description
In December, 1995 the Hubble Space Telescope pointed at a
undistinguished high-galactic latitude patch of sky and observed
for 10 straight days.
The result was the deepest optical image of
the sky yet obtained, allowing sources as faint as $V = 30$ in
four bandpasses spanning the near-UV to the near-IR (Williams et al. 1996, AJ, 112, 1335 ).
The data were
released to the community within one month of the observations and
have been used in a wide variety of projects and publications,
ranging from studies of the star-formation rate as a function of redshift,
to studies of faint M dwarfs in the Galactic halo
A second Hubble Deep Field campaign will be carried out with HST in
October 1998. The observations will be much the same as the original HDF, with
several important differences:
\begin{enumerate}
- The field is located in the southern Continuous Viewing Zone
(J2000 coordinates 22:32:56.2 -60:33:02.7)
- A moderate redshift quasar of z ~ 2.24
identified by Boyle, Hewett, Weymann (1997) and colleagues,
will be placed in the STIS field for both
imaging and spectroscopy so that correlations between quasar absorption
redshifts and the redshifts of galaxies in the fields may be determined.
- Simultaneous, parallel observations will be made with the three HST
instruments WFPC2, NICMOS, and STIS of separate, neighboring fields.
The STIS and NICMOS data will be a significant enhancement over what
was possible for HDF-N.
