Free Free¶
- class cosmoglobe.sky.components.freefree.LinearOpticallyThin(amp, freq_ref, **spectral_parameters)[source]¶
Class representing the free-free component in the Cosmoglobe Sky Model.
Notes
The free-free emission is defined using the convention in BeyondPlanck (2020), Section 3.3.2;
\[\boldsymbol{s}_\mathrm{RJ}^{\mathrm{ff}}(\nu) \propto \frac{g_{\mathrm{ff}}(T_\mathrm{e})}{\nu^2},\]where \(\nu\) is the frequency for which we are simulating the sky emission, \(g_\mathrm{ff}\) is the Gaunt factor, and \(T_\mathrm{e}\) is the electron temperature.
