A Newly-Discovered Radio Halo in Merging Cluster MACS J2243.3-0935
T. M. Cantwell, A. M. M. Scaife, N. Oozeer +2
We report the discovery of a radio halo in the massive merging cluster MACSJ2243.3-0935, as well as a new radio relic candidate, using the Giant Meterwave Radio Telescope and the K…
The scaling relations and the fundamental plane for radio halos and relics of galaxy clusters
Z. S. Yuan, J. L. Han, Z. L. Wen
Diffuse radio emission in galaxy clusters is known to be related to cluster mass and cluster dynamical state. We collect the observed fluxes of radio halos, relics, and mini-halos…
Substructure and dynamical state of 2092 rich clusters of galaxies derived from photometric data
Z. L. Wen, J. L. Han
Dynamical state of galaxy clusters is closely related to their observational properties in X-ray, optical and radio wavelengths. We develop a method to diagnose the substructure an…
Updated catalog of 132,684 galaxy clusters and evolution of brightest cluster galaxies
Z. L. Wen, J. L. Han
We identified 132,684 clusters in the redshift range of 0.05<z<0.8 from SDSS DR8. The spectroscopic redshifts of 52,683 clusters have been included in the catalog using SDSS DR9 da…
Influence of major mergers on the radio emission of elliptical galaxies
Y. H. Wen, Z. L. Wen, J. L. Han +1
We investigate the influence of major mergers on the radio emission of elliptical galaxies. We use a complete sample of close pairs, which contains 475 merging and 1828 non-merging…
The correlation function of galaxy clusters and detection of baryon acoustic oscillations
T. Hong, J. L. Han, Z. L. Wen +2
We calculate the correlation function of 13,904 galaxy clusters of z \leq 0.4 selected from the cluster catalog of Wen, Han & Liu. The correlation function can be fitted with a pow…
A catalog of 132,684 clusters of galaxies identified from Sloan Digital Sky Survey III
Z. L. Wen, J. L. Han, F. S. Liu
Using the photometric redshifts of galaxies from the Sloan Digital Sky Survey III (SDSS-III), we identify 132,684 clusters in the redshift range of 0.05<z<0.8. Monte Carlo simulati…
Galaxy clusters at high redshift and evolution of brightest cluster galaxies
Z. L. Wen, J. L. Han
Identification of high redshift clusters is important for studies of cosmology and cluster evolution. Using photometric redshifts of galaxies, we identify 631 clusters from the Can…
Mass Function of Rich Galaxy Clusters and Its Constraint on sigma_8
Z. L. Wen, J. L. Han, F. S. Liu
The mass function of galaxy clusters is a powerful tool to constrain cosmological parameters, e.g., the mass fluctuation on the scale of 8 h^{-1} Mpc, sigma_8, and the abundance of…
Mergers of luminous early-type galaxies
Z. L. Wen, J. L. Han, F. S. Liu
We have made a careful selection of a large complete volume-limited sample (1209) of projected close pairs (7<r_p<50 kpc) of luminous early-type galaxies (M_r<-21.5) in the local u…
Ultra-luminous Infrared Galaxies in Sloan Digital Sky Survey Data Release 6
L. G. Hou, Xue-Bing Wu, J. L. Han
Ultra-luminous infrared galaxies (ULIRGs) are interesting objects with dramatic properties. Many efforts have been made to understand the physics of their luminous infrared emissio…
Galaxy clusters identified from the SDSS DR6 and their properties
Z. L. Wen, J. L. Han, F. S. Liu
Clusters of galaxies in most previous catalogs have redshifts z<0.3. Using the photometric redshifts of galaxies from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6), we ide…
