Abstract:
Deep representative surveys of galaxies at different epochs are needed
to make progress in understanding galaxy evolution. We describe the
completed VIMOS VLT Deep Survey and the final data release of 35016
galaxies and type-I AGN with measured spectroscopic redshifts covering
all epochs up to redshift z∼6.7, in areas from 0.142 to 8.7 square
degrees, and volumes from 0.5x106 to 2x107h-3*Mpc3. We
selected samples of galaxies based solely on their i-band magnitude
reaching iAB=24.75. Spectra were obtained with VIMOS on the ESO-VLT
integrating 0.75h, 4.5h, and 18h for the Wide, Deep, and Ultra-Deep
nested surveys, respectively. We demonstrate that any "redshift
desert" can be crossed successfully using spectra covering
3650≤λ≤9350Å. A total of 1263 galaxies were again observed
independently within the VVDS and from the VIPERS and MASSIV surveys.
They were used to establish the redshift measurements reliability, to
assess completeness in the VVDS sample, and to provide a weighting
scheme taking the survey selection function into account. We describe
the main properties of the VVDS samples, and the VVDS is compared to
other spectroscopic surveys in the literature. In total we have
obtained spectroscopic redshifts for 34594 galaxies, 422 type-I AGN,
and 12430 Galactic stars. The survey enabled identifying galaxies up
to very high redshifts with 4669 redshifts in 1≤zspec≤2, 561 in
2≤zspec≤3, and 468 with zspec>3, and specific populations like
Lyman-α emitters were identified out to z=6.62. We show that the
VVDS occupies a unique place in the parameter space defined by area,
depth, redshift coverage, and number of spectra. The VIMOS VLT Deep
Survey provides a comprehensive survey of the distant universe,
covering all epochs since z∼6, or more than 12Gyr of cosmic time, with
a uniform selection, which is the largest such sample to date. A
wealth of science results derived from the VVDS have shed new light on
the evolution of galaxies and AGN and on their distribution in space
over this large cosmic time. The VVDS further demonstrates that large
deep spectroscopic redshift surveys over all these epochs in the
distant Universe are a key tool to observational cosmology. To enhance
the legacy value of the survey, a final public release of the complete
VVDS spectroscopic redshift sample is available at
http://cesam.lam.fr/vvds .
Description:
We have presented the VVDS surveys as completed, including the
VVDS-Wide, VVDS-Deep, VVDS-Ultra-Deep, and VVDS-LAE. In total the VVDS
has measured spectroscopic redshifts for 34594 galaxies and 422 AGN
over a redshift range 0.007≤zspec≤6.62, and over an area up to
8.7deg2, for magnitude-limited surveys with a depth down to
iAB=24.75 and line flux F=1.5x1018erg/s/cm2. The VVDS-Wide sample
sums up to 25805 galaxies with IAB≤22.5 over 0<z<2, and a mean
spectroscopic redshift =0.55. The VVDS-Deep contains 11486 galaxies
with 17.5≤IAB≤24.0 over 0<z<5 and =0.92. The VVDS Ultra-Deep
contains 938 galaxies with measured redshifts with 23≤iAB≤24.75 over
0<z<4.5 and =1.38. The VVDS-LAE sample adds 133 serendipitously
discovered LAE to the high-redshift populations with 2<z≤6.62.
