Abstract / Description of output
We present the general real- and redshift-space clustering properties of
galaxies as measured in the first data release of the VIPERS survey.
VIPERS is a large redshift survey designed to probe in detail the
distant Universe and its large-scale structure at 0.5 <z <1.2.
We describe in this analysis the global properties of the sample and
discuss the survey completeness and associated corrections. This sample
allows us to measure the galaxy clustering with an unprecedented
accuracy at these redshifts. From the redshift-space distortions
observed in the galaxy clustering pattern we provide a first measurement
of the growth rate of structure at z = 0.8: fσ8 = 0.47
± 0.08. This is completely consistent with the predictions of
standard cosmological models based on Einstein gravity, although this
measurement alone does not discriminate between different gravity
models.
Based on observations collected at the European Southern Observatory,
Cerro Paranal, Chile, using the Very Large Telescope under programmes
182.A-0886 and partly 070.A-9007. Also based on observations obtained
with MegaPrime/MegaCam, a joint project of CFHT and CEA/DAPNIA, at the
Canada-France-Hawaii Telescope (CFHT), which is operated by the National
Research Council (NRC) of Canada, the Institut National des Sciences de
l'Univers of the Centre National de la Recherche Scientifique (CNRS) of
France, and the University of Hawaii. This work is based in part on data
products produced at TERAPIX and the Canadian Astronomy Data Centre as
part of the Canada-France-Hawaii Telescope Legacy Survey, a
collaborative project of NRC and CNRS. The VIPERS web site is http://www.vipers.inaf.it/
