Constraints on $Ω_{m}$ and $σ_{8}$ from the potential-based cluster temperature function

Christian Angrick, Francesco Pace, Matthias Bartelmann +1

The abundance of galaxy clusters is in principle a powerful tool to constrain cosmological parameters, especially $Ω_{m}$ and $σ_{8}$ , due to the exponential dependence in the…

Ellipticity and prolaticity of the initial gravitational-shear field at the position of density maxima

Christian Angrick

Dark-matter haloes are supposed to form at the positions of maxima in the initial matter density field. The gravitational-shear field's ellipticity and prolaticity that serve as in…

The influence of mergers on the cluster temperature function and cosmological parameters derived from it

Christian Angrick, Matthias Bartelmann

We develop a parameter-free analytic model to include the effects of mergers into the theoretical modelling of the X-ray temperature function of galaxy clusters. We include this de…
