Euclid: Impact of halo mass-conversion model assumptions on galaxy cluster number-count analyses
The research tested how different methods for converting halo mass definitions introduce biases when using galaxy cluster counts to constrain cosmology. It compared parametric deterministic, parametric stochastic, and non-parametric stochastic approaches. The findings show that the non-parametric method is robust, while the other two methods introduce significant systematic biases depending on the assumed mass profile.
