Galaxies (skypy.galaxy
)¶
This module contains methods that model the intrinsic properties of galaxy populations.
Luminosities (skypy.galaxy.luminosity
)¶
Models of galaxy luminosities.
Models¶
Model of Herbel et al (2017) |
Ellipticities (skypy.galaxy.ellipticity
)¶
Galaxy ellipticity module.
This module provides facilities to sample the ellipticities of galaxies.
Models¶
Galaxy ellipticities sampled from a reparameterized beta distribution. |
Redshifts (skypy.galaxy.redshift
)¶
Galaxy redshift module.
This module provides facilities to sample galaxy redshifts using a number of models.
Models¶
Redshift following the Schechter luminosity function marginalised over luminosities following the Herbel et al. |
|
Calculates the redshift pdf of the Schechter luminosity function according to the model of Herbel et al. |
|
Redshifts following the Smail et al. |
Sizes (skypy.galaxy.size
)¶
Galaxy size module.
This modules computes the angular size of galaxies from their physical size.
Utility functions¶
Angular size of a galaxy. |
Models¶
Lognormal distribution for early-type galaxies. |
|
Lognormal distribution for late-type galaxies. |
|
Lognormal distribution with linear mean. |
Spectra (skypy.galaxy.spectrum
)¶
Galaxy spectrum module.
Models¶
Dirichlet-distributed SED coefficients. |
