Modeling Galaxy Clustering with Cosmological Simulations
I review recent progress in understanding and modeling galaxy clustering in cosmological simulations, with emphasis on models based on high-resolution dissipationless simulations. During the last decade, significant advances in our understanding of abundance and clustering of dark matter halos allowed construction of accurate, quantitative models of galaxy clustering both in linear and non-line...
متن کاملSimulations of Early Galaxy Formation
We present the predictions for the photometric and emission line properties of galaxies present during the latter stages of reionization from z = 8 → 6. These preliminary predictions are made from cosmological hydrodynamic simulations that include star formation and feedback, but not the effects of radiative transfer. We find significant numbers of galaxies that have stellar masses exceeding 10...
متن کاملNumerical Simulations of Galaxy Formation
An overview over the current status of modeling galaxies by means of numerical simulations is given. After a short description of how galaxies form in hierarchically clustering scenarios, success and failures of current simulations are demonstrated using three different applications: the morphology of present day galaxies; the appearance of high redshift galaxies; and the nature of the Ly-α for...
متن کاملEvolution of Faint Galaxy Clustering
The UH8K wide field camera of the CFHT was used to image 0.68 deg2 of sky. From these images, ∼20,000 galaxies were detected to completeness magnitudes V < 23.5 and I < 22.5. The angular correlation function of these galaxies is well represented by the parameterization ω(θ) = AW θ−δ . The slope δ ' −0.8 shows no significant variation over the range of magnitude. The amplitude AW decreases with ...
متن کاملMeasures of the galaxy clustering
A brief introduction is given to some aspects of the statistical description of the luminous matter distribution. I review the features of the redshift surveys that arise in the statistical analysis of the galaxy clustering. Special topics include intensity functions, correlation functions, correlation integrals, multifractals and multiscaling.
