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 Britton On Sat, Aug 2, 2014 at 8:43 PM, Brendan Griffen <brendan.f.griffen@gmail.com
