relations.f_gas(M500, hubble=0.7)[source]#

Use the relationship between M500 and f_gas = Mgas/Mtot within r500 from Vikhlinin, A., et al. 2009, ApJ, 692, 1033 (https://ui.adsabs.harvard.edu/abs/2009ApJ…692.1033V/).

Parameters:

  • M500 (float) – The M500 of the cluster in units of Msun.

  • hubble (float, optional) – The Hubble parameter in units of 100 km/s/Mpc. Default: 0.7

Return type:

f_gas at r500
