critical density calculation from yt
Hi, I'm using the cosmology.critical_density(z) calculation from yt and I was wondering what is the exact type of critical density? Is it baryon critical density? That is what I need. Thanks. Brendan
Hi Brendan,
Cosmology.critical_density returns the total closure density of the
universe at that redshift. Do you want the mean baryon density? If so, I
suggest you do:
Cosmology.critical_density(z) * omega_baryon_now * (1 + current_redshift)**3
