CONSTRAINTS ON COSMOLOGICAL PARAMETERS FROM GALAXY CLUSTERS: tSZ CLUSTER COUNTS AND POWER SPECTRUM COMBINED WITH CMB
Résumé
We present constraints on cosmological parameters from a first combination oftSZ number counts and power spectrum, constraining the ΛCDM model and someextentions, in particular the effect of massive neutrinos and an equation ofstate for dark energy different from the standard value. We compare theseresults with CMB primary anisotropies constraints. We show how the uncertaintieson these results are still dominated by systematics related to the theoreticalmodel, in particular the mass bias, for which we propose a parametrisation withrespect to mass and redhisft.
