## Summary:

- I have been trying to track down the most current published value for Omega_r. The most recent (?) I have found is 0.824 x 10^-4. There is a list of references, but I am not sure which was the source of the value. My guess it might be the one dated 2017.

The source of the 0.824×10

I also looked at the Planck 2018, paper I but could not find a value for Ω

Any suggestions would be greatly appreciated.

BTW: The reason behind this search is I want to calculate the best value I can for the time at which the gravitational influences of radiation and matter are the same.

_{r}. I searched the internet with:radiation density cosmology friedmann omega

but I had no success. I also looked at Planck 2013 and found the value 0.92364×10^{-4}.Any suggestions would be greatly appreciated.
