The dark matter halo mass function dependence on the halo's dynamical states

Not scheduled




eROSITA will provide a large amount of galaxy
clusters, with the possibility to obtain halo mass functions
with improved precision. A key point in this context is understanding the selec-
tion effects in galaxy clusters surveys with a cosmological
purpose. An interesting feature is the dynamical state of the
dark matter halo. Relaxed halos are supposed to host cool
core galaxy clusters, making them easier to detect in the
X-ray. On the contrary, non cool core clusters are hosted
by unrelaxed halos. We investigate the variations of the mass
function as a function of the dynamical state of the con-
stituting halos.
