The VIMOS - VLT Deep Survey
Aims. We use the VVDS-Deep first-epoch survey data to measure the dependence of galaxy clustering on galaxy stellar mass, at an effective redshift z ∼ 0.85. Methods. We measure the projected correlation function, w p (r p), for sub-samples in the 0.5 < z < 1.2 interval covering different mass ranges between ∼ 10 9.0 and ∼ 10 11 M ⊙. We explore and quantify in detail the observational selection ...
متن کاملThe Vimos VLT Deep Survey: Compact structures in the CDFS
We have used the Vimos VLT Deep Survey in combination with other spectroscopic, photometric and X-ray surveys from literature to detect several galaxy structures in the Chandra Deep Field South (CDFS). Both a friend-of-friend based algorithm applied to the spectroscopic redshift catalog and an adaptative kernel galaxy density and colour maps correlated with photometric redshift estimates have b...
متن کاملEarly results from the VIMOS VLT Deep Survey
The VIMOS VLT Deep Survey (VVDS) is underway to study the evolution of galaxies, large scale structures and AGNs, from the measurement of more than 100000 spectra of faint objects. We present here the results from the first epoch observations of more than 20000 spectra. The main challenge of the program, the redshift measurements, is described, in particular entering the “redshift desert” in th...
متن کاملAccurate photometric redshifts for the CFHT Legacy Survey calibrated using the VIMOS VLT Deep Survey
We present and release photometric redshifts for an uniquely large and deep sample of 522286 objects with i′AB ≤ 25 in the Canada-France Legacy Survey “Deep Survey” fields D1, D2, D3, and D4, which cover a total effective area of 3.2 deg. We use 3241 spectroscopic redshifts with 0 ≤ z ≤ 5 from the VIMOS VLT Deep Survey as a calibration and training set to derive these photometric redshifts. Usi...
متن کاملThe VIMOS VLT Deep Survey: Computing the two point correlation statistics and associated uncertainties
We are presenting in this paper a detailed account of the methods used to compute the three-dimensional two-point galaxy correlation function in the VIMOS-VLT deep survey (VVDS). We investigate how instrumental selection effects and observational biases affect the measurements and identify the methods to correct them. We quantify the accuracy of our correction method using an ensemble of fifty ...
