Galaxy-galaxy weak-lensing measurement from SDSS: II. host halo properties of galaxy groups

Wentao Luo, Xiaohu Yang, Tianhuan Lu +10

As the second paper of a series on studying galaxy-galaxy lensing signals using the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modelling of…

The gap of stellar mass in galaxy groups: another perspective of the Too-big-To-Fail problem in the Milky Way

Xi Kang, L. Wang, Y. Luo

The Milky Way presents the too-big-to-fail (TBTF) problem that there are two observed satellite galaxies with maximum circular velocity larger than 55km/s, and others have velocity…

Spin alignments of spiral galaxies within the large-scale structure from SDSS DR7

Youcai Zhang, Xiaohu Yang, Huiyuan Wang +4

Using a sample of spiral galaxies selected from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) and Galaxy Zoo 2 (GZ2), we investigate the alignment of spin axes of spiral g…

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…

Cross identification between X-ray and Optical Clusters of Galaxies in the SDSS DR7 Field

Lei Wang, Xiaohu Yang, Wentao Luo +5

We use the ROSAT all sky survey X-ray cluster catalogs and the optical SDSS DR7 galaxy and group catalogs to cross-identify X-ray clusters with their optical counterparts, resultin…
