Notice: Illustris[TNG] data and websites will be offline for maintenance Nov 4 (Tuesday), 2025, from 2am EST. Expected downtime is 36 hours.
As stated in the Data Specifications, the electron number density can be calculated as:
n_e = ElectronAbundance ∗ n_H, where n_H = X_H ∗ ρ/m_p
So in this formula, I know that X_H=0.76 is the hydrogen mass fraction. How about the ρ and m_p?
Thank you in advance, Thang Huynh
rho is the symbol for mass density, i.e. PartType0/Density (in the appropriate units).
PartType0/Density
m_p is the proton mass.
Oh I see, thank you very much for your information.
