Hubble Deep Field South

It followed the great success of the original Hubble Deep Field in facilitating the study of extremely distant galaxies in early stages of their evolution.

It also has a nearby bright star, as well as a moderately strong radio source close by, but in both cases it was decided that these wouldn't compromise follow-up observations.

[4] Viewing this field, however, has some issues due to passages through the South Atlantic Anomaly and also with scattered earthshine during daylight hours; the latter can be avoided by using instruments with larger sources of noise, for example from the CCD reading process, at those times.

Translational changes were fine during the imaging parts of the observation; however, the telescope had to be rotated by small amounts instead of repointed during the spectroscopic work, such that the centre of the STIS instrument was kept on the central quasar.

The quasar provides a probe of the gas along the line of sight where the foreground objects are also observed, allowing an investigation into the association of galaxies with absorption features.

Many studies of the HDF-S confirmed results found from the HDF-N, such as star formation rates over the lifetime of the universe.
