Dear all,
I am quite new to HI intensity mapping issues and I am having a very naive question plz: Does computing the 21cm angular power spectra for 0 < z < 5 require radical changes to the "standard" CAMB_source as per Lewis & Challinor. If yes, could you point me to a significant change required.
Thanks & regards
Patrice
Computing 21cm angular power spectra for 0 < z < 5 with the std. CAMB_source?

Yes, CAMB sources only does the dark ages up to the onset of reionization. Thereafter the spin temperature evolution is much more complicated and cannot be determined in linear theory.
