darkhistory.physics.elec_heating_engloss_rate(eng, xe, rs)

Electron energy loss rate of electrons due to Coulomb heating in eV s-1.

Parameters:
eng : ndarray

Abscissa of electron kinetic energy.

xe : float

The free electron fraction.

rs : float

The redshift.

Returns:
ndarray

The energy loss rate due to heating (positive).

Notes

See 0910.4410 for the expression. The units have e^2/r being in units of energy, so to convert to SI, we insert 1/(4*pi*eps_0)^2.
