The MUSE Hubble Ultra Deep Field surveys: Data release II

Understand

We present the second data release of the MUSE Hubble UDF surveys, which includes the deepest spectroscopic survey ever performed.

• The MUSE data, with their 3D content, amazing depth, wide spectral range, and excellent spatial and medium spectral resolution, are rich in information.
• This update of the first release incorporates a new 141-hour adaptive-optics-assisted MXDF field (1' diameter FoV) in addition to the reprocessed 10-hour mosaic (3'x3') and the single 31-hour deep field (1'x1').
• We have securely identified and measured the redshift of 2221 sources, an increase of 41% compared to the first release.
