The VIRMOS-VLT Deep Survey
نویسندگان
چکیده
The aim of the VIRMOS VLT Deep Survey (VVDS) is to study of the evolution of galaxies, large scale structures and AGNs from a sample of more than 150,000 galaxies with measured redshifts in the range 0 ≤ z ≤ 5+. The VVDS will rely on the VIMOS and NIRMOS wide field multi-object spectrographs, which the VIRMOS consortium is delivering to ESO. Together, they offer unprecedented multiplex capability in the wavelength range 0.37 − 1.8μm, allowing for large surveys to be carried out. The VVDS has several main aspects: (1) a deep multi-color imaging survey over 18deg of more than one million galaxies, (2) a ”wide” spectroscopic survey with more than 130,000 redshifts measured for objects brighter than IAB = 22.5 over 18deg , (3) a ”deep” survey with 50,000 redshifts measured to IAB = 24, (4) ”ultra-deep” surveys with several thousand redshifts measured to IAB = 25, (5) multi-wavelength observations with the VLA and XMM.

The VIRMOS deep imaging survey: I. overview and survey strategy
This paper presents the CFH12K-VIRMOS survey: a deep B, V, R and I imaging survey in four fields totalling more than 17 deg, conducted with the 30× 40 arcmin field CFH-12K camera. The survey is intended to be a multi-purpose survey used for a variety of science goals, including surveys of very high redshift galaxies and weak lensing studies. Four high galactic latitude fields, each 2 × 2 deg, h...
متن کاملThe VLA - VIRMOS Deep Field I . Radio observations probing the μ Jy source population
We have conducted a deep survey (r.m.s noise ≃ 17µJy) with the Very Large Array (VLA) at 1.4 GHz, with a resolution of 6 arcsec, of a 1 deg 2 region included in the VIRMOS VLT Deep Survey. In the same field we already have multiband photometry down to IAB = 25, and spectroscopic observations will be obtained during the VIRMOS VLT survey. The homogeneous sensitivity over the whole field has allo...
متن کاملDiscovery of a z = 6 . 17 galaxy from CFHT and VLT observations ⋆
We report the discovery of a galaxy at a redshift z = 6.17 identified from deep narrow band imaging and spectroscopic follow-up in one of the CFHT-VIRMOS deep survey fields at 0226-04. In addition to the existing deep BVRI images of this field, we obtained a very deep narrow band image at 920 nm with the aim of detecting Lyα emission at redshift ∼ 6.5. Spectroscopic follow-up of some of the can...
متن کاملThe VIRMOS deep imaging survey II: CFH12K BVRI optical data for the 0226-04 deep field⋆
In this paper we describe in detail the reduction, preparation and reliability of the photometric catalogues which comprise the CFH12K-VIRMOS deep field. This region, consisting of four contiguous pointings of the CFH12K wide-field mosaic camera, covers a total area of 1.2 deg. The survey reaches a limiting magnitude of BAB ∼ 26.5, VAB ∼ 26.2, RAB ∼ 25.9 and IAB ∼ 25.0 (corresponding to the poi...
متن کاملThe VIRMOS deep imaging survey : III . ESO / WFI deep U - band imaging of the 0226 - 04 deep field . ⋆
In this paper we describe the U−band imaging of the F02 deep field, one of the fields in the VIRMOS Deep Imaging Survey. The observations were done at the ESO/MPG 2.2m telescope at La Silla (Chile) using the 8k × 8k Wide-Field Imager (WFI). The field is centered at α(J2000)=02 h 26 m 00 s and δ(J2000)=-04 • 30 ′ 00 ′′ , the total covered area is 0.9 deg 2 and the limiting magnitude (50% complet...
