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.
