class pyccl.halos.concentration.ishiyama21.ConcentrationIshiyama21(self, *, mass_def='500c', relaxed=False, Vmax=False)[source]

Bases: Concentration

Concentration-mass relation by Ishiyama et al. 2021. This parametrization is only valid for S.O. masses with \(\Delta = \Delta_{\rm vir}\), or \(\Delta=200\) or \(500\) times the critical density. By default it will be initialized for \(M_{500c}\).

Parameters:

  • mass_def (MassDef or str) – a mass definition object or a name string.

  • relaxed (bool) – If True, use concentration for relaxed halos. Otherwise, use concentration for all halos. Default: False.

  • Vmax (bool) – If True, use the concentration found with the “Vmax” numerical method. Otherwise, use the concentration found with profile fitting. Default: False.
