A cross-correlation-based estimate of the galaxy luminosity function
van Daalen, White
Extend existing methods for using cross-correlations to derive redshift distributions for photometric galaxies, without using photometric redshifts. The model presented in this paper simultaneously yields highly accurate and unbiased redshift distributions and, for the first time, redshift-dependent luminosity functions, using only clustering information and the apparent magnitudes of the galaxies as input. In contrast to many existing techniques for recovering unbiased redshift distributions, the output of the method is not degenerate with the galaxy bias b(z), which is achieved by modeling the shape of the luminosity bias. Successfully apply the method to a mock galaxy survey and discuss the potential application to the model to real data.
