Galaxy bias refers to the relative density of galaxies compared to underlying dark matter, and can be a function of scale and/or redshift.
Jullo et al made measurements of galaxy bias for high and low mass samples.
This module compares a predicted b(z) or b(k,z) from theory to these measurements.
Assumptions¶
