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…
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…
Alignments of galaxies within cosmic filaments from SDSS DR7
Youcai Zhang, Xiaohu Yang, Huiyuan Wang +3
Using a sample of galaxy groups selected from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we examine the alignment between the orientation of galaxies and their surroun…
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…
