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, wp(rp), for sub-samples in the 0.5 < z < 1.2 interval covering different mass ranges between ∼ 109.0 and ∼ 1011 M⊙. We explore and quantify in(More)
Observations of distant supernovae indicate that the Universe is now in a phase of accelerated expansion the physical cause of which is a mystery. Formally, this requires the inclusion of a term acting as a negative pressure in the equations of cosmic expansion, accounting for about 75 per cent of the total energy density in the Universe. The simplest(More)
To understand the evolution of galaxies, we need to know as accurately as possible how many galaxies were present in the Universe at different epochs. Galaxies in the young Universe have hitherto mainly been identified using their expected optical colours, but this leaves open the possibility that a significant population remains undetected because their(More)
The VIMOS VLT Deep Survey (VVDS), designed to measure 150,000 galaxy redshifts, requires a dedicated data reduction and analysis pipeline to process in a timely fashion the large amount of spectroscopic data being produced. This requirement has lead to the development of the VIMOS Interactive Pipeline and Graphical Interface (VIPGI), a new software package(More)
We present luminosity functions of galaxies per spectral type derived from the first epoch observations of the VIMOS VLT Deep Survey (VVDS) out to z = 1.5. The VVDS data allow for the first time to study from the same sample and with good statistical accuracy the evolution of the luminosity functions per galaxy type in several rest frame bands from a purely(More)
Aims. We present a measurement of the dependence of galaxy clustering on galaxy stellar mass at redshift z ∼ 0.9, based on the first-epoch data from the VVDS-Deep survey. Methods. Concentrating on the redshift interval 0.5 < z < 1.2, we measure the projected correlation function, wp(rp), within mass-selected subsamples covering the range ∼ 109 and ∼ 1011(More)
From the first epoch observations of the VIMOS VLT Deep Survey (VVDS) up to z = 1.5 we have derived luminosity functions of different spectral type galaxies. The VVDS data, covering ∼ 70% of the life of the Universe, allow for the first time to study from the same sample and with good statistical accuracy the evolution of the luminosity functions by galaxy(More)
Context. Understanding the relationship between the formation and evolution of galaxies and their central super massive black holes (SMBH) is one of the main topics in extragalactic astrophysics. Links and feedback may reciprocally affect both black hole and galaxy growth. Aims. Observations of the CO line at redshifts of 2-4 are crucial to investigate the(More)
Context. The VVDS-Wide survey has been designed with the general aim of tracing the large-scale distribution of galaxies at z ∼ 1 on comoving scales reaching ∼ 100h−1 Mpc, while providing a good control of cosmic variance over areas as large as a few square degrees. This is achieved by measuring redshifts with VIMOS at the ESO VLT to a limiting magnitude(More)
In this paper we present the optical and near-infrared identifications of the 1054 radio sources detected in the 20cm deep radio survey down to a 5σ flux limit of ∼80μJy obtained with the VLA in the VIMOS VLT Deep Survey VVDS-02h deep field. Using U, B,V,R, I and K data, with limiting magnitudes of UAB ∼25.4, BAB ∼26.5, VAB ∼26.2, RAB ∼25.9 IAB ∼25.0, JAB(More)
