We use the effective field theory of dark energy to explore the space of modified gravity
models which are capable of driving the present cosmic acceleration. We identify five
universal functions of cosmic time that are enough to describe a wide range of theories …

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 …

The clustering ratio η, a large-scale structure observable originally designed to constrain the
shape of the power spectrum of matter density fluctuations, is shown to provide a sensitive
probe of the nature of gravity in the cosmological regime. We apply this analysis to F (R) …

We present the first Public Data Release (PDR-1) of the VIMOS Public Extragalactic Survey
(VIPERS). It comprises 57 204 spectroscopic measurements together with all additional
information necessary for optimal scientific exploitation of the data, in particular the …

We provide a formula for extracting the value of the rms of the linear matter fluctuations on a
scale R directly from redshift survey data. It allows us to constrain the real-space amplitude
of σ R without requiring any modelling of the nature and power spectrum of the matter …

Aims. The aim of this work is to develop a comprehensive method for classifying sources in
large sky surveys and to apply the techniques to the VIMOS Public Extragalactic Redshift
Survey (VIPERS). Using the optical (u∗, g′, r′, i′) and near-infrared (NIR) data (z′, K s) …

Abstract We develop a Principal Component Analysis aimed at classifying a subset of 27
350 spectra of galaxies in the range 0.4< z< 1.0 collected by the VIMOS Public Extragalactic
Redshift Survey (VIPERS). We apply an iterative algorithm to simultaneously repair parts of …

Our proper acceleration with respect to the cosmic microwave background results in a real-
time change of the angular position of distant extragalactic sources. The cosmological
component of this aberration drift signal, the noninertial motion generated by the large-scale …
