4. Nucleosynthesis I. Aretxaga
 

Summary: 4. Nucleosynthesis
I. Aretxaga
2010
We have that MR-3
radR-4
There must be a z at which M= rad
Taking into account that nucleosynthesis predicts n=0.68 n , then rad=4.2 x 10-5 h-2
1+zeq = 23900mh2
zeq 3100

(From M. Plionis' notes or Peacock 1999)
Epochs in the evolution of the Universe
Quite sudden transition from radiation to matter dominated Universe
at z~3100 (t~60000 yr):
recombination
