Relative clustering and the joint halo occupation distribution of red-sequence and blue-cloud galaxies in COMBO-17

Understand

This paper studies the relative spatial distribution of red-sequence and blue-cloud galaxies, and their relation to the dark matter distribution in the COMBO-17 survey as function of scale down to z~1.

• We measure the 2nd-order auto- and cross-correlation functions of galaxy clustering and express the relative biasing by using aperture statistics.
• Also estimated is the relation between the galaxies and the dark matter distribution exploiting galaxy-galaxy lensing (GGL).
• All observables are further interpreted in terms of a halo model.
