Abstract: Galaxy alignment means that the major axes or spins of galaxies in large-scale structures tend to point to some specific directions. The anisotropy of orientations is indeed related to galaxy formation and evolution, and provide rich information on the large scale structures in the universe. I will introduce galaxy alignments and my recent work on using galaxy alignments to probe the clusters of galaxies and large-scale filaments.

Bio: Mr. Yu Rong is a Ph.D. student under the guidance of Prof. Shuang-Nan Zhang in the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences (CAS). His primary research areas include galaxy formation and evolution, and large-scale structures. In 2009, Yu Rong obtained the undergraduate degree in the Dept. of Astronomy in the University of Science and Technology of China (USTC). He will be expected to receive his Ph.D. degree at IHEP in 2016, with the research in the galaxy alignments in large-scale structures.
