Abstract:
This paper prepares a series of papers analysing the Intermediate MAss
Galaxy Evolution Sequence (IMAGES) up to a redshift of one.
Intermediate mass galaxies (M_J≤-20.3) are selected from the Chandra
Deep Field South (CDFS) for which we identify a serious lack of
spectroscopically determined redshifts.
Our primary aim in this study is therefore to obtain a sample of
intermediate-mass galaxies with known spectroscopic redshift to be
used for further analysis of their 3D-kinematics. We also intend to
test whether this important cosmological field may be significantly
affected by cosmic variance.
The spectroscopic observations were carried out using VIMOS on the ESO
VLT. The data reduction was done using a set of semi-automatic IRAF
procedures developed by our team.
We have spectroscopically identified 691 objects including 580
galaxies, 7 QSOs, and 104 stars.
