The VIMOS Ultra - Deep Survey ( VUDS ) : IGM transmission towards galaxies with 2 . 5 < z < 5 . 5 and the colour selection of high redshift galaxies ⋆
The observed UV rest-frame spectra of distant galaxies are the result of their intrinsic emission combined with absorption along the line of sight produced by the inter-galactic medium (IGM). Here we analyse the evolution of the mean IGM transmission T r(Lyα) and its dispersion along the line of sight for 2127 galaxies with 2.5 < z < 5.5 in the VIMOS Ultra Deep Survey (VUDS). We fit model spect...
متن کاملThe VIMOS - VLT Deep Survey ⋆ Evolution of the galaxy luminosity function up to z = 2 in first epoch data
We investigate the evolution of the galaxy luminosity function from the VIMOS-VLT Deep Survey (VVDS) from the present to z = 2 in five (U , B, V , R and I) rest-frame band-passes. We use the first epoch VVDS deep sample of 11,034 spectra selected at 17.5 ≤ IAB ≤ 24.0, on which we apply the Algorithm for Luminosity Function (ALF), described in this paper. We observe a substantial evolution with ...
متن کاملThe DEEP 2 Galaxy Redshift Survey : Environments of Poststarburst Galaxies at z ∼ 0 . 1 and z ∼ 0 . 8
Poststarburst (also known as K+A) galaxies exhibit spectroscopic signatures indicating that their star formation was recently quenched; they are candidates for galaxies in transition from a star-forming phase to a passively-evolving phase. We have spectroscopically identified large samples of poststarburst galaxies both in the Sloan Digital Sky Survey (SDSS) at z ∼ 0.1 and in the DEEP2 Galaxy R...

Poststarburst galaxies exhibit spectroscopic signatures indicating that their star formation was recently quenched; they are candidates for galaxies in transition from a star-forming phase to a passively-evolving phase. We have spectroscopically identified large samples of poststarburst galaxies both in the SDSS survey at z ∼ 0.1 and in the DEEP2 survey at z ∼ 0.8, using a uniform and robust se...
متن کاملThe VIMOS Ultra Deep Survey: Lyα Emission and Stellar Populations
The aim of this paper is to investigate spectral and photometric properties of 854 faint (iAB . 25 mag) star-forming galaxies (SFGs) at 2< z< 2.5 using the VIMOS Ultra-Deep Survey (VUDS) spectroscopic data and deep multi-wavelength photometric data in three extensively studied extragalactic fields (ECDFS, VVDS, COSMOS). These SFGs were targeted for spectroscopy based on their photometric redshi...
