Breaking Halo Occupation Degeneracies with Marked Statistics
We show that a suitably defined marked correlation function can be used to break degeneracies in halo-occupation distribution modeling. The statistic can be computed on both 3D and 2D data sets, and should be applicable to all upcoming galaxy surveys. A proof of principle, using mock catalogs created from N-body simulations, is given.
متن کاملThe halo-model description of marked statistics
Marked statistics allow sensitive tests of how galaxy properties correlate with environment, as well as of how correlations between galaxy properties are affected by environment. A halo-model description of marked correlations is developed, which incorporates the effects which arise from the facts that typical galaxy marks (e.g., luminosity, color, star formation rate, stellar mass) depend on t...
متن کاملThe halo by halo missing baryon problem
The global missing baryon problem — that the sum of observed baryons falls short of the number expected form BBN — is well known. In addition to this, there is also a local missing baryon problem that applies to individual dark matter halos. This halo by halo missing baryon problem is such that the observed mass fraction of baryons in individual galaxies falls short of the cosmic baryon fractio...
متن کاملGalaxy Groups in the Sdss Dr4: Ii. Halo Occupation Statistics
We investigate various galaxy occupation statistics of dark matter halos using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) with an adaptive halo-based group finder. The conditional luminosity function (CLF), which describes the luminosity distribution of galaxies in halos of a given mass, is measured separately for all, red and blue gal...
متن کاملGravitational Lensing Statistics and Density Profile of Dark Halo
We investigate the influence of the inner profile of the lens objects on gravitational lensing statistics taking into account of the effect of the magnification bias and both the evolution and the scatter of halo profiles. We take the dark matter halos as the lens objects and consider the following three models for the density profile of the dark matter halo; SIS (singular isothermal sphere), t...
