On the measurement of the Hubble constant in a local low-density universe
Xiang-Ping Wu, Zugan Deng, Zhenlong Zou +2
Astrophysical observations indicate that the ``Local Universe" has a relatively lower matter density () than the predictions of the standard inflation cosmology and the large-…
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…
Substructures of Clusters and Cosmological Models
Y. P. Jing, H. J. Mo, G. Boerner +1
We investigate, using high resolution N-body simulations, the density profiles and the morphologies of galaxy clusters in three models of structure formation. We show that these pr…
FeII and FeI emission in IRAS 07598+6508 and PHL 1092
John Kwan, Fu-zhen Cheng, Li-Zhi Fang +2
One of the puzzles in understanding the spectra of active galactic nuclei (AGN) is the origin of the FeII emission. FeI emission, if present, will help reveal the physical conditio…
An Infrared Cutoff Revealed by the Two Years of COBE-DMR Observations of Cosmic Temperature Fluctuations
Yi-Peng Jing, Li-Zhi Fang
We show that a good fitting to the first two years of {\it COBE}-DMR observations of the two-point angular correlation function of CBR temperature is given by models with a non-zer…
Abundance of moderate-redshift clusters in the Cold + Hot dark matter model
Y. P. Jing, L. Z. Fang
Using a set of $\pppm$ simulation which accurately treats the density evolution of two components of dark matter, we study the evolution of clusters in the Cold + Hot dark matter (…
