The MUSE 3D view of the Hubble Deep Field South
The MUSE integral field spectrograph on the ESO VLT obtains spectra for every 0.2 arcsecond pixel within a 1-arcminute square. As part of its recent commissioning, the MUSE consortium obtained a 27-hour exposure of one field within the Hubble Deep Field South. The resulting spectroscopic survey is one of the deepest to date, with redshifts measured for galaxies up to I=29.5, as well as for significant numbers of galaxies that are not detected in the deep HST WFPC2 images, and it is also by far the densest survey ever. These early results demonstrate how blind surveys with MUSE will constrain the evolution of faint galaxies at high redshift.
