Is the initial mass function universal in galaxies? A MaNGA view

I will provide a review about the evidence for variation of the initial mass function (IMF) in galaxies from gravitational lensing, and more importantly, from dynamics using SDSS-IV MaNGA data. Implications for a non-universal IMF will be briefly discussed.

Speaker Introduction: 

Prof. Mao's research interests are mainly on the dynamics of galaxies, the structure of the Milky Way, gravitational lensing and searching for extrasolar planets with microlensing. More recently, he also became interested in gravitational waves because of the first direct detection.  Prof. Mao obtained his bachelor degree from USTC (1988, China), PhD from Princeton (1992). He was a CfA Fellow at Harvard from 1992 to 1995. He then travelled around, spending almost 5 years in Germany (Max-Planck Institute for Astrophysics) and 10 years in the UK (Manchester), becoming a full professor in 2006. He eventually returned to China with his family (叶落归根) through the one thousand talent program (千人计划).
