Anisotropy and characteristic scales in halo density gradient profiles
X. Wang, H. Wang, H. J. Mo
We use a large N-body simulation to study the characteristic scales in the density gradient profiles in and around halos with masses ranging from to $10^{15} h^{-1}{\rm M…
Hosts and triggers of AGNs in the Local Universe
Ziwen Zhang, Huiyuan Wang, Wentao Luo +11
Based on the spectroscopic and shear catalogs for SDSS galaxies in the local Universe, we compare optically-selected active galactic nuclei (AGNs) with control star-forming and qui…
Constraining the HI-Halo Mass Relation From Galaxy Clustering
Hong Guo, Cheng Li, Zheng Zheng +5
We study the dependence of galaxy clustering on atomic gas mass using a sample of 16,000 galaxies with redshift in the range of and HI mass of $M_{\rm HI}>10^…
ELUCID - Exploring the Local Universe with reConstructed Initial Density field I: Hamiltonian Markov Chain Monte Carlo Method with Particle Mesh Dynamics
Huiyuan Wang, H. J. Mo, Xiaohu Yang +2
Simulating the evolution of the local universe is important for studying galaxies and the intergalactic medium in a way free of cosmic variance. Here we present a method to reconst…
Measuring the X-ray luminosities of SDSS DR7 clusters from RASS
Lei Wang, Xiaohu Yang, Shiyin Shen +8
We use ROSAT All Sky Survey (RASS) broadband X-ray images and the optical clusters identified from SDSS DR7 to estimate the X-ray luminosities around candidate cluste…
Stellar Ages and Metallicities of Central and Satellite Galaxies: Implications for Galaxy Formation and Evolution
Anna Pasquali, Anna Gallazzi, Fabio Fontanot +4
Using a large SDSS galaxy group catalogue, we study how the stellar ages and metallicities of central and satellite galaxies depend on stellar mass and halo mass. We find that sate…
Inclination-Dependent Luminosity Function of Spiral Galaxies in the Sloan Digital Sky Survey: Implication for Dust Extinction
Zhengyi Shao, Quanbao Xiao, Shiyin Shen +3
Using a samples of 61506 spiral galaxies selected from the SDSS DR2, we examine the luminosity function (LF) of spiral galaxies with different inclination angles. We find that the…
Understanding the Results of Galaxy-Galaxy Lensing using Galaxy-Mass Correlation in Numerical Simulations
XiaoHu Yang, H. J. Mo, Guinevere Kauffmann +1
McKay et al. (2002) have recently used measurements of weak galaxy-galaxy lensing in the Sloan Digital Sky Survey to estimate the cross correlation between galaxies and the project…
Analytical Approximations to Galaxy Clustering
H. J. Mo
We discuss some recent progress in constructing analytic approximations to the galaxy clustering. We show that successful models can be constructed for the clustering of both dark…
Constraints on the Cosmic Structure Formation Models from Early Formation of Giant Galaxies
H. J. Mo, M. Fukugita
A recent observation of Steidel et al. indicates that a substantial fraction of giant galaxies were formed at an epoch as early as redshift . We show that this early forma…
High-Order Correlations of Peaks and Halos: a Step toward Understanding Galaxy Biasing
H. J. Mo, Y. P. Jing, S. D. M. White
We develop an analytic model for the hierarchical correlation amplitudes S_j(R)= \bxi_j(R)/\bxi_2^{j-1}(R) of density peaks and dark matter halos in the quasi-linear regime. The st…
An analytic model for the spatial clustering of dark matter haloes
H. J. Mo, S. D. M. White
We develop a simple analytic model for the gravitational clustering of dark matter haloes to understand how their spatial distribution is biased relative to that of the mass. The s…
