Abstract: Quenched massive spiral galaxies have attracted great attention recently, as more data is available to constrain their environment and cold gas content. However, the quenching mechanism is still uncertain. In this talk, we report the identification of a rare population of very massive, quenched spiral galaxies with stellar mass
and halo mass from the Sloan Digital Sky Survey at redshift
Bio: Xi Kang, the professor at the physics department of Zhejiang University and the director of the joint astronomy center between ZJU and Purple Mountain Observatory, CAS. He got his PhD in 2005 from the Shanghai Astronomical Observatory, and worked as a postdoc between 2005-2009 at the university of Oxford, Max-Planck-Institute for Astronomy. In 2009, He joined PMO and led the galaxy and cosmology group. He is now involving the buildup of astrophysics in ZJU. His main research interest focus on galaxy formation and the large-scale structure.
