"Updated Results on the Galaxy-Halo Connection from Satellite Kinematics in SDSS"
I will present new results on the relationship between central galaxies and dark matter halos inferred from observations of satellite kinematics in the Sloan Digital Sky Survey (SDSS) DR7. We employ an updated analysis framework that includes detailed mock catalogues to model observational effects in SDSS. Our results constrain the color-dependent conditional luminosity function (CLF) of dark matter halos, as well as the radial profile of satellite galaxies. Confirming previous results, we find that red central galaxies live in more massive halos than blue galaxies at fixed luminosity. Additionally, our results suggest that satellite galaxies have a radial profile less centrally concentrated than dark matter but not as cored as resolved subhalos in dark matter-only simulations. Compared to previous works using satellite kinematics by More et al. (2011), we find much more competitive constraints on the galaxy-halo connection, on par with those derived from a combination of galaxy clustering and galaxy-galaxy lensing. I will also compare our results on the galaxy-halo connection to other studies using galaxy clustering, galaxy-galaxy lensing and group catalogues, showing very good agreement between these different techniques. This resolves the tension between satellite kinematics results, as previously reported by More et al. (2011), and other probes.
