Modeling Galaxy-Galaxy Weak Lensing with SDSS Groups (2008)
Li, Ran, Mo, H. J., Fan, Zuhui, Cacciato, Marcello, Yang, Xiaohu, ...
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 galaxies of different...
Probing for cosmological parameters with LAMOST measurement (2008)
Li, Hong, Xia, Jun-Qing, Fan, Zuhui, Zhang, Xinmin
In this paper we study the sensitivity of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) project to the determination of cosmological parameters, employing the Monte Carlo...
Probing the intrinsic shape and alignment of dark matter haloes using SDSS galaxy groups (2008)
Wang, Yougang, Yang, Xiaohu, Mo, H. J., Li, Cheng, Van Den Bosch, Frank C., Fan, Zuhui, ...
Probing the Intrinsic Shape and Alignment of Dark Matter Haloes using SDSS Galaxy Groups (2007)
Wang, Yougang, Yang, Xiaohu, Mo, H. J., Li, Cheng, Fan, Zuhui, ...
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 central galaxy and the...
Constraints on Dark Energy Models Including Gamma Ray Bursts (2006)
Li, Hong, Su, Meng, Fan, Zuhui, Dai, Zigao, Zhang, Xinmin
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 long Gamma-Ray...
Gamma Ray Bursts: Complementarity to Other Cosmological Probes (2006)
Su, Meng, Li, Hong, Fan, Zuhui, Liu, Bo
We combine recent long Gamma Ray Bursts (GRBs) sample including 52 objects out to z$=$6.3 compiled from Swift Gamma Ray Bursts by Schaefer (2006) with Type Ia Supernova (SNIa), Cosmic Microwave...
Circumnuclear Spiral Arms and Starburst Rings in Magnetized Barred Spiral Galaxies (2001)
Lou, Yu-Qing, Fan, ZuHui, Yuan, Chi, Leon, Stephane
The Seyfert galaxy NGC 1097 has an extended neutral hydrogen disk, a companion, a prominent bar and a luminous circumnuclear starburst "ring". Magnetic fields as revealed by nonthermal...
We study Sunyaev-Zeldovich Effect (SZE) cluster counts in different cosmologies. It is found that even without the full knowledge of the redshift distribution of SZE clusters, one can still readily...
Distributions of Fourier Modes of Cosmological Density Fields (1995)
We discuss the probability distributions of Fourier modes of cosmological density fields using the central limit theorem as it applies to weighted integrals of random fields. It is shown that if the...
