Nuisance parameters for large galaxy surveys
Sandrine Codis
These notes are based on a lecture given at the 2016 Euclid Summer School in Narbonne. I will first give a quick overview of the concept of nuisance parameters in the context of la…
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…
Non Gaussian Minkowski functionals and extrema counts for 2D sky maps
Dmitri Pogosyan, Sandrine Codis, Christophe Pichon
In the conference presentation we have reviewed the theory of non-Gaussian geometrical measures for the 3D Cosmic Web of the matter distribution in the Universe and 2D sky data, su…
Encircling the dark: constraining dark energy via cosmic density in spheres
S. Codis, C. Pichon, F. Bernardeau +2
The recently published analytic probability density function for the mildly non-linear cosmic density field within spherical cells is used to build a simple but accurate maximum li…
Redshift and luminosity evolution of the intrinsic alignments of galaxies in Horizon-AGN
Nora Elisa Chisari, Clotilde Laigle, Sandrine Codis +7
Intrinsic galaxy shape and angular momentum alignments can arise in cosmological large-scale structure due to tidal interactions or galaxy formation processes. Cosmological hydrody…
The large-scale correlations of multi-cell densities and profiles, implications for cosmic variance estimates
Sandrine Codis, Francis Bernardeau, Christophe Pichon
In order to quantify the error budget in the measured probability distribution functions of cell densities, the two-point statistics of cosmic densities in concentric spheres is in…
