The VIMOS Public Extragalactic Redshift Survey (VIPERS). Gravity test from the combination of redshift-space distortions and galaxy-galaxy lensing at
S. de la Torre, E. Jullo, C. Giocoli +39
We carry out a joint analysis of redshift-space distortions and galaxy-galaxy lensing, with the aim of measuring the growth rate of structure; this is a key quantity for understand…
Two is better than one: joint statistics of density and velocity in concentric spheres as a cosmological probe
Cora Uhlemann, Sandrine Codis, Oliver Hahn +2
The analytical formalism to obtain the probability distribution functions (PDFs) of spherically-averaged cosmic densities and velocity divergences in the mildly non-linear regime i…
The VIMOS Public Extragalactic Redshift Survey: Measuring the growth rate of structure around cosmic voids
A. J. Hawken, B. R. Granett, A. Iovino +33
We identified voids in the completed VIMOS Public Extragalactic Redshift Survey (VIPERS), using an algorithm based on searching for empty spheres. We measured the cross-correlation…
The VIMOS Public Extragalactic Redshift Survey (VIPERS). The matter density and baryon fraction from the galaxy power spectrum at redshift
S. Rota, B. R. Granett, J. Bel +37
We use the final catalogue of the VIMOS Public Extragalactic Redshift Survey (VIPERS) to measure the power spectrum of the galaxy distribution at high redshift, presenting results…
Clustering-based redshift estimation: application to VIPERS/CFHTLS
V. Scottez, Y. Mellier, B. R. Granett +36
We explore the accuracy of the clustering-based redshift estimation proposed by Ménard et al. (2013) when applied to VIPERS and CFHTLS real data. This method enables us to reconstr…
A new method to assign galaxy cluster membership using photometric redshifts
Gianluca Castignani, Christophe Benoist
We introduce a new effective strategy to assign group and cluster membership probabilities to galaxies using photometric redshift information. Large dynamical ranges both…
