GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
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…
Connections between galaxy mergers and Starburst: evidence from local Universe
Wentao Luo, Xiaohu Yang, Youcai Zhang
Major mergers and interactions between gas-rich galaxies with comparable masses are thought to be the main triggers of starburst. In this work, we study, for a large stellar mass r…
