# Joint cosmology and mass calibration from thermal Sunyaev-Zel’dovich cluster counts and cosmic shear

@article{Nicola2020JointCA, title={Joint cosmology and mass calibration from thermal Sunyaev-Zel’dovich cluster counts and cosmic shear}, author={A. Nicola and Jo Dunkley and David N. Spergel}, journal={arXiv: Cosmology and Nongalactic Astrophysics}, year={2020} }

We present a new method for joint cosmological parameter inference and cluster mass calibration from a combination of weak lensing measurements and the abundance of thermal Sunyaev-Zel'dovich (tSZ) selected galaxy clusters. We combine cluster counts with the spherical harmonic cosmic shear power spectrum and the cross-correlation between cluster overdensity and cosmic shear. These correlations constrain the cluster mass-observable relation. We model the observables using a halo model framework… Expand
