Class

NumCosmoRecombSeager

Description [src] 

class NumCosmo.RecombSeager : NumCosmo.Recomb
{
  /* No available fields */
}

Cosmic recombination implementing Seager (1999).

Cosmic recombination as initially described in Seager (1999) and Seager (2000). The code includes all modifications as in recfast 1.5.2, including those discussed in Wong (2008). The matter-temperature modification of Scott (2009) is not included: the more robust integration method used here makes it unnecessary.

This object solves the coupled system for the singly ionized hydrogen $X_\mathrm{HII}$, singly ionized helium $X_\mathrm{HeII}$, and the baryon temperature $T_m$, with Case B recombination coefficients from #nc_recomb_seager_pequignot_HI_case_B (hydrogen) and

nc_recomb_seager_hummer_HeI_case_B (helium). The NcRecombSeagerOpt flags select the

$K$ factors and whether the triplet contribution is included.

For the full evolution equations, Boltzmann factors, and rate definitions, see the theoretical background page: Cosmic Recombination.
