A newly released mosaic image from Hubble, with 4 billion pixels, covering a square of sky about 1/2o wide, with an angular resolution of 0.05", and a depth of 24 or 25 mag.
"Not only does the GEMS study cover a large area at high resolution; it is also a three-dimensional map. Of the 60,000 or so galaxies that have been identified in the mosaic, distances have been found for 10,000 using another deep survey of the same area carried out with a 2.2-meter telescope at the European La Silla observatory in Chile."
"Jogee [a GEMS team member] looks forward to learning more about multiple-galaxy interactions, black-hole formation, the host galaxies of active galactic nuclei (of which there are about 80 in the survey), and mergers of spirals to become ellipticals. Of course, the observers work closely with theorists who devise ever-more-detailed computer simulations of the various physical processes that play a role in galactic evolution."
"This is becoming a very well-studied bit of sky. The GEMS field coincides with the extended Chandra Deep Field, which was imaged in X-rays by the Chandra X-Ray Observatory. The central fifth of the GEMS field is being imaged more deeply by the many-wavelength GOODS Survey. And within the GOODS area we will soon see will the smaller, deeper Hubble Ultra-Deep Field (UDF), the size of a single ACS camera frame. The UDF is currently scheduled for release in March."
