Bases:
object
Profile of central galaxies residing at the exact center of their host halo with the exact same velocity as the halo velocity.
\(P(\vec{x}_{\rm cen}, \vec{v}_{\rm cen}) = \delta^{(6)}(\vec{x}_{\rm halo}, \vec{v}_{\rm halo})\).
- Parameters:
- cosmologyobject, optional
Astropy cosmology object. Default is set in
sim_defaults
.- redshiftfloat, optional
Default is set in
sim_defaults
.- mdef: str
String specifying the halo mass definition, e.g., ‘vir’ or ‘200m’. Default is set in
model_defaults
.
