SHAO Astrophysics Colloquium

Title:   New Observational Perspectives on the Galaxy's Central Bulge/Bar System

Speaker: Mike Rich (UCLA)

Time 3pm, September 18 (Monday) 
Location: Lecture Hall, 3rd floor


The center of the Milky Way hosts 2x10^10 Solar masses of stars in its central 5,000 light years.  This central region is of great interest because the stars have signs of a formation history that is very different from the vicinity of our Sun- a history in which successive generations of supernovae built up the elements we observe today.  I will review what we know about this region and report on new results, from a new map of the velocities of stars that suggests that the

bulge/bar formed from a the buckling of a massive disk, to investigations of the properties of red giant stars lying only 1 parsec from the central black hole, to the global kinematics of red giants hosting SiO maser sources. The unusual characteristics and formation history of this region informs us about the history of galaxy formation in general.

The Astrophysics division is the main group engaged in astrophysical research at Shanghai Astronomical Observatory. Research areas include active galactic nuclei and high energy astrophysics, galaxy formation and evolution, cosmology and large scale structure, star clusters and the structure of the Milk Way, star formation, and planetary astrophysics. There are now 45 faculty members, 16 postdocs, and 65 graduate students in the division.

The Astrophysics division maintains close partnerships with many astronomical research institutes, including the joint Key laboratory of research in galaxies and cosmology of CAS with University of Science and Technology of China, the joint astrophysics center with Xiamen University. Members of the astrophysics division also participate in many international and domestic astronomical projects, including LAMOST, HXMT, FAST, the Sloan Digital Sky Survey IV, TMT, LSST, etc.
