ELUCID -- Exploring the Local Universe with the reConstructed Initial Density field. II: Reconstruction diagnostics, applied to numerical halo catalogs
Dylan Tweed, Xiaohu Yang, Huiyuan Wang +5
The ELUCID project aims to build a series of realistic cosmological simulations that reproduce the spatial and mass distribution of the galaxies as observed in the Sloan Digital Sk…
Clustering properties and halo masses for central galaxies in the local Universe
Lixin Wang, Cheng Li, Y. P. Jing
We investigate the clustering and dark matter halo mass for a sample of 16,000 central galaxies selected from the SDSS/DR7 group catalog. We select subsamples of central gala…
Resolving Subhaloes' Lives with the Hierarchical Bound-Tracing Algorithm
Jiaxin Han, Y. P. Jing, Huiyuan Wang +1
We develop a new code, the Hierarchical Bound-Tracing (HBT for short) code, to find and trace dark matter subhaloes in simulations based on the merger hierarchy of dark matter halo…
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Wenting Wang, Y. P. Jing, Cheng Li +2
We develop a new method which measures the projected density distribution w_p(r_p)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultan…
Systematic Effects on Determination of the Growth Factor from Redshift-space Distortions
Teppei Okumura, Y. P. Jing
The linear growth factor of density perturbations is believed to be a powerful observable of future redshift surveys to probe physical properties of dark energy and to distinguish…
Influence of baryonic physics on the merger time-scale of galaxies in N-body/hydrodynamical simulations
C. Y. Jiang, Y. P. Jing, W. P. Lin
Following our previous work(Jiang et al.(2008)), in which we studied the merger time-scale of galaxies in a high-resolution cosmological hydro/N-body simulation, we investigate the…
The distribution of ejected subhalos and its implication for halo assembly bias
Huiyuan Wang, H. J. Mo, Y. P. Jing
Using a high-resolution cosmological -body simulation, we identify the ejected population of subhalos, which are halos at redshift but were once contained in more massive…
Intrinsic Ellipticity Correlation of SDSS Luminous Red Galaxies and Misalignment with their Host Dark Matter Halos
Teppei Okumura, Y. P. Jing, Cheng Li
We investigate the orientation correlation of giant elliptical galaxies by measuring the intrinsic ellipticity correlation function of 83,773 luminous red galaxies (LRGs) at redshi…
Warm Dark Matter Model of Galaxy Formation
Y. P. Jing
Cold Dark Matter (CDM) models of galaxy formation had been remarkably successful to explain a number of observations in the past decade. However, with both the theoretical modeling…
Nonlinear Stochastic Biasing of Galaxies and Dark Halos in Cosmological Hydrodynamic Simulations
Kohji Yoshikawa, Atsushi Taruya, Y. P. Jing +1
We perform an extensive analysis of nonlinear and stochastic biasing of galaxies and dark halos in spatially flat low-density CDM universe using cosmological hydrodynamic simulatio…
A new test for the stable clustering hypothesis
Y. P. Jing
The stable clustering hypothesis is a fundamental assumption about the nonlinear clustering of matter in cosmology. It states that the mean physical separation of particles is a co…
The Scaling of the Redshift Power Spectrum: Observations from the Las Campanas Redshift Survey
Y. P. Jing, G. Boerner
In a recent paper we have studied the redshift power spectrum in three CDM models with the help of high resolution simulations. Here we apply the method to the largest a…
The Three-point Correlation Function of Galaxies Determined from the Las Campanas Redshift Survey
Y. P. Jing, G. Boerner
We report the measurement of the three-point correlation function (3PCF) of galaxies for the Las Campanas Redshift Survey (LCRS). We have not only measured the 3PCF in redshift spa…
The Pairwise Peculiar Velocity Dispersion of Galaxies: Effects of the Infall
Y. P. Jing, G. Boerner
We study the reliability of the reconstruction method which uses a modelling of the redshift distortions of the two-point correlation function to estimate the pairwise peculiar vel…
Spatial correlation function and pairwise velocity dispersion of galaxies: CDM models versus the Las Campanas Survey
Y. P. Jing, H. J. Mo, G. Boerner
We show, with the help of large N-body simulations, that the real-space two-point correlation function and pairwise velocity dispersion of galaxies can both be measured reliably fr…
The velocity dispersion profiles of clusters of galaxies: a cosmological test and the sampling effect
Y. P. Jing, G. Boerner
In this paper we investigate the velocity dispersion profiles of clusters of galaxies for seven cosmological models. One model is the SCDM model, and the others are six low-density…
Three-point correlation function of galaxy clusters in cosmological models: a strong dependence on triangle shape
Y. P. Jing, G. Boerner, R. Valdarnini
In this paper, we use large $\pppm$ N-body simulations to study the three-point correlation function of clusters in two theoretical models. The first model (LCDM) is a low-dens…
Substructures and Density Profiles of Clusters in Models of Galaxy Formation
Y. P. Jing, H. J. Mo, G. Boerner +1
In this paper we investigate, using high resolution N-body simulations, the density profiles and the morphologies of galaxy clusters in seven models of structure formation. We show…
The large-scale structure in a universe dominated by cold plus hot dark matter
Y. P. Jing, H. J. Mo, G. Boerner +1
Using numerical simulations, we investigate the large-scale gravitational clustering in a flat universe dominated by cold plus hot dark matter (i.e., $Ω_0=\ocdm+\ohdm+\obaryon=1$).…
