TL;DR
This paper reports the public release of 1599 galaxy redshifts from the VIMOS VLT Deep Survey in the Chandra Deep Field South, achieving high completeness and identifying significant galaxy density peaks up to redshift ~4.
Contribution
First large-scale, high-completeness redshift survey in the CDFS with publicly available data and detailed galaxy distribution analysis.
Findings
Redshift distribution peaks at z=0.73 with a high-redshift tail up to ~4.
Achieved 88% secure redshift measurement completeness.
Identified significant galaxy density peaks, including a prominent peak at z=0.735.
Abstract
{This paper presents the VIMOS VLT Deep Survey around the Chandra Deep Field South (CDFS). We have measured 1599 new redshifts with VIMOS on the European Observatory Very Large Telescope - UT3, in an area 21x21.6 arcmin^2, including 784 redshifts in the Hubble Space Telescope - Advanced Camera for Surveys GOODS area. 30% of all objects with I_AB=24 have been observed independently of magnitude, indicating that the sample is purely magnitude limited. We have reached an unprecedented completeness level of 88% in terms of the ratio of secure measurements vs. observed objects, while 95% of all objects have a redshift measurement. A total of 1452 galaxies, 139 stars, 8 QSOs have a redshift identification, 141 of these being unsecure measurements. The redshift distribution down to I_AB=24 is peaked at a median redshift z=0.73, with a significant high redshift tail extending up to ~4. Several…
