synthesizer.components.blackhole

A module for holding blackhole emission models.

The class defined here should never be instantiated directly, there are only ever instantiated by the parametric/particle child classes. BlackholesComponent is a child class of Component.

Classes

class synthesizer.components.blackhole.BlackholesComponent(fesc, mass=None, accretion_rate=None, epsilon=0.1, accretion_rate_eddington=None, inclination=unyt_quantity(0., 'degree'), spin=None, bolometric_luminosity=None, metallicity=None, ionisation_parameter_blr=0.1, hydrogen_density_blr=unyt_quantity(1.e+09, 'cm**(-3)'), covering_fraction_blr=0.1, velocity_dispersion_blr=unyt_quantity(2000, 'km/s'), ionisation_parameter_nlr=0.01, hydrogen_density_nlr=unyt_quantity(10000., 'cm**(-3)'), covering_fraction_nlr=0.1, velocity_dispersion_nlr=unyt_quantity(500, 'km/s'), theta_torus=unyt_quantity(10, 'degree'), **kwargs)

The parent class for stellar components of a galaxy.

This class contains the attributes and spectra creation methods which are common to both parametric and particle stellar components.

This should never be instantiated directly, instead it provides the common functionality and attributes used by the child parametric and particle BlackHole/s classes.
