Spectroscopic surveys in astrophysics and cosmology require an accurate knowledge of the non-uniformity in the transmission of light introduced by the telescope optics, which yields a non-uniform response all over the focal plane. In this work, we report a preliminary study on the in-flight flux self-calibration procedure and we characterize...

We present a method for the in-flight relative flux self-calibration of a spectro-photometer instrument, general enough to be applied to any upcoming galaxy survey on satellite. The instrument response function, that accounts for a smooth continuous variation due to telescope optics, on top of a discontinuous effect due to the segmentation of...

Aims. Non-uniform sampling and gaps in sky coverage are common in galaxy redshift surveys, but these effects can degrade galaxy counts-in-cells measurements and density estimates. We carry out a comparative study of methods that aim to fill the gaps to correct for the systematic effects. Our study is motivated by the analysis of the VIMOS...

We present new constraints on the relationship between galaxies and their host dark matter haloes, measured from the location of the peak of the stellar-to-halo mass ratio (SHMR), up to the most massive galaxy clusters at redshift z similar to 0.8 and over a volume of nearly 0.1 Gpc(3). We use a unique combination of deep observations in the...
