Modeling Galaxy-Galaxy Weak Lensing with SDSS Groups
Ran Li, H. J. Mo, Zuhui Fan +4
We use galaxy groups selected from the Sloan Digital Sky Survey (SDSS) together with mass models for individual groups to study the galaxy-galaxy lensing signals expected from gala…
Probing the Intrinsic Shape and Alignment of Dark Matter Haloes using SDSS Galaxy Groups
Yougang Wang, Xiaohu Yang, H. J. Mo +4
We study the three-dimensional and projected shapes of galaxy groups in the Sloan Digital Sky Survey Data Release 4, and examine the alignment between the orientation of the centra…
Intrinsic alignments of galaxies and their effects on weak lensing detections of mass concentrations
Z. H. Fan
In this paper we investigate the influence of the intrinsic alignment of background galaxies on weak lensing detections of mass concentrations. Specifically, we analyze the number…
Constraints on Dark Energy Models Including Gamma Ray Bursts
Hong Li, Meng Su, Zuhui Fan +2
In this paper we analyze the constraints on the property of dark energy from cosmological observations. Together with SNe Ia Gold sample, WMAP, SDSS and 2dFGRS data, we include 69…
Gamma Ray Bursts: Complementarity to Other Cosmological Probes
Meng Su, Hong Li, Zuhui Fan +1
We combine recent long Gamma Ray Bursts (GRBs) sample including 52 objects out to z6.3 compiled from Swift Gamma Ray Bursts by Schaefer (2006) with Type Ia Supernova (SNIa), Cos…
Systematic errors in the determination of Hubble constant due to the asphericity and non-isothermality of clusters of galaxies
Y. -G. Wang, Z. -H. Fan
Joint analyses on X-ray and Sunyaev-Zel'dovich (SZ) effect of a cluster of galaxies can give rise to an estimate on the angular diameter distance to the cluster. With the redshift…
The distribution of two-dimensional eccentricity of Sunyaev-Zeldovich Effect and X-ray surface brightness profiles
Y. -G. Wang, Z. -H. Fan
With the triaxial density profile of dark matter halos and the corresponding equilibrium gas distribution, we derive two-dimensional Sunyaev-Zeldovich (SZ) effect and X-ray surface…
The Effects of Relativistic Corrections on Cosmological Parameter Estimations from SZE Cluster Surveys
Z. H. Fan, Y. L. Wu
Sunyaev-Zel'dovich Effect (SZE) cluster surveys are anticipated to yield tight constraints on cosmological parameters such as the equation of state of dark energy. In this paper, w…
