# The MUSE Hubble Ultra Deep Field Survey

We present the MUSE Hubble Ultra Deep Survey, a mosaic of nine MUSE fields covering 90% of the entire HUDF region with a 10-hour deep exposure time, plus a deeper 31-hour exposure in a single 1.15 arcmin² field. From this unique data set  we derive 1338 high quality redshifts, which is a factor of eight increase compared with the previously known spectroscopic redshifts in the same field. The redshift distribution extends well beyond z > 3 and to HST/F775W magnitudes as faint as ≈ 30 mag (AB). In addition a number of sources were discovered without HST counterpart.

This survey enables new and detailed studies of the physical properties of the galaxy population and their environments over a large redshift range.  The main results are described in a series of 10 papers published in A&A:
