CosmoMC: Massive neutrinos
Posted: May 23 2006
In the original form, the cosmomc code has the number of massive neutrinos = 3, but has the neutrino fraction of dark matter equal to zero.
Am I right in understanding that these are included as a contribution to Omega-radiation before the epoch of matter-radiation equality? Obviously that would depend on the mass.
I was slightly confused about how exactly the code treats this issue. I would be grateful if you could please clarify this.
