Linking the Global and Spatially Resolved SFR-M* Relations and Molecular Gas Properties 
of MaNGA Galaxies / Dr Hsi-an Pan (Institute of Astronomy & Astrophysics, Academia 
Sinica)

The galaxy integrated star formation rate(SFR)-stellar mass(M) relation holds important 
information for understanding the star formation history and evolution of galaxies. 
Although the SFR-M relation has been reported with a variety of different data sets, 
their appearance can vary significantly from one to another. In this work, we determine 
what controls the integrated and the spatially-resolved SFR-M* relation in both 
star-forming and quiescent galaxies by linking the resolved SFR-M* relation with 
various galaxy properties such as stellar mass, specific SFR (sSFR), bulge-to-total 
light ratio, and morphology using MaNGA data (Mapping Nearby Galaxies at APO).

In this talk, in addition to MaNGA, I will also introduce the current status of 
molecular gas observations of MaNGA galaxies. Molecular gas represents the material 
immediately available for forming new stars. A direct comparison between stellar 
populations and molecular gas is required to understand the star formation in galaxies. 
We use CO data to trace molecular gas content in MaNGA galaxies and compare their 
stellar properties and gas properties, such as gas fraction and star formation 
efficiency of gas.
