- Description:
- VIMOS Public Extragalactic Redshift Survey" (VIPERS) is an ongoing ESO Large Program to map in detail the spatial distribution of normal galaxies over an unprecedented volume of the z~1 Universe. VIPERS is using VIMOS at the VLT to measure 100,000 redshifts for galaxies with red magnitude I(AB) brighter than 22.5 over an area of 24 square degrees. At this redshift, VIPERS fills a unique niche in galaxy surveys, optimizing the combination of 5-band accurate photometry from the CFHTLS with the multiplexing capability of VIMOS. A robust color-color pre-selection allows the survey to focus its measurements on the 0.5 <= z <= 1.2 redshift range, yielding an optimal combination of large volume (5 x 107 h-3 Mpc3) and high effective spectroscopic sampling (> 40%). With these figures, the VIPERS data set represents the z~1 equivalent of state-of-the-art "local" (z<=0.2) surveys. VIPERS scientific investigations focus on measurements of large-scale structure and cosmological parameters at an epoch when the Universe was about half its current age. At the same time, the survey can explore the ensemble properties of luminous galaxies, groups and clusters with unprecedented statistical accuracy at these redshifts.

- Description:
- The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies selected to have Iab < 22.5 across the full 1.7 deg2 of the COSMOS field. This part, "zCOSMOS-bright", was designed to yield a high and fairly uniform sampling rate (about 70%), with a high success rate in measuring redshifts (approaching 100% at 0.5 < z < 0.8), and with sufficient velocity accuracy (about 100 km/s) to efficiently map the environments of galaxies down to the scale of galaxy groups out to redshifts z ~ 1.
