Dependence of cosmic shear covariances on cosmology - Impact on parameter estimation
Dependence of cosmic shear covariances on cosmology - Impact on parameter estimation
In cosmic shear likelihood analyses the covariance is most commonly assumed to be constant in parameter space. Therefore, when calculating the covariance matrix (analytically or from simulations), its underlying cosmology should not influence the likelihood contours. We examine whether the aforementioned assumption holds and quantify how strong cosmic shear covariances …
