The Dark Side of Galaxy Color: evidence from new SDSS measurements of galaxy clustering and lensing
Andrew P. Hearin, Douglas F. Watson, Matthew R. Becker +3
The age matching model has recently been shown to predict correctly the luminosity L and g-r color of galaxies residing within dark matter halos. The central tenet of the model is…
Galaxy Assembly Bias: A Significant Source of Systematic Error in the Galaxy-Halo Relationship
Andrew R. Zentner, Andrew P. Hearin, Frank C. van den Bosch
It is common practice for methods that use galaxy clustering to constrain the galaxy-halo relationship, such as the halo occupation distribution (HOD) and/or conditional luminosity…
Prospects for Detecting Gamma Rays from Annihilating Dark Matter in Dwarf Galaxies in the Era of DES and LSST
Chen He, Keith Bechtol, Andrew P. Hearin +1
Among the most stringent constraints on the dark matter annihilation cross section are those derived from observations of dwarf galaxies by the Fermi Gamma-Ray Space Telescope. As…
The Dark Side of Galaxy Color
Andrew P. Hearin, Douglas F. Watson
We present age distribution matching, a theoretical formalism for predicting how galaxies of luminosity L and color C occupy dark matter halos. Our model supposes that there are ju…
