lfkit.cosmo.cosmology

Cosmology utilities for LFKit.

This module provides wrappers around PyCCL cosmology objects and background calculations.

It standardizes how cosmology instances are created and how lookback time is computed, ensuring consistent behavior across LFKit.

All returned quantities are NumPy arrays of dtype float.

Functions

comoving_distance_mpc(cosmo_obj, z)	Compute comoving radial distance in megaparsecs.
cosmo_object(*[, instance])	Return a PyCCL cosmology object.
differential_comoving_volume(cosmo_obj, z[, ...])	Compute differential comoving volume per unit redshift.
distance_modulus(cosmo_obj, z[, h])	Compute distance modulus.
lookback_time_gyr(cosmo_obj, z)	Compute lookback time in gigayears.
luminosity_distance_mpc(cosmo_obj, z)	Compute luminosity distance in megaparsecs.
