In this talk, I will present the work we did in Cuesta-Lazaro et al. (2020, arXiv:2002.02683). I will first remind the ingredients we need to get a prediction of the redshift-space clustering of galaxies and extract constraints on the growth rate of structures. Then, I will present the improvement of the modelling of the galaxy pairwise velocities at small scales we proposed using the Skew-T...
In this talk, I will present a work I did (publication under collaboration review) where I measured the Baryon Acoustic Oscillations in the projected cross-correlation function binned into transverse comoving radius between the SDSS-IV DR16 eBOSS quasars and a dense photometric sample of emission line galaxies selected from the DESI Legacy Imaging Surveys, which enables to constrain the...
Abstract :
Nous avons mené une étude sommaire afin d'avoir une approximation des résultats qui pourraient être obtenus dans le cas de corrélations croisées entre les sondes Galaxy Clustering spectroscopiques (GCsp) et les sondes photométriques (Galaxy Clustering photométrique - GCph - et Lentillage faible - Weak Lensing - WL). L'approche consiste à assimiler les bins spectroscopiques et une...
