I will present our analysis results on the mid-J CO line emission over galaxy scale from a large sample of local luminous infrared galaxies (LIRGs) observed with Herschel Space Observatory and the CO (6-5) line emission over a scale of 30-100 pc in the nuclei of representative LIRGs observed with ALMA. The mid-J CO line emission acts as the cooling mechanism for the dense molecular gas that is giving birth to and also receiving energetic feedback from young stars. I will highlight what we have learnt from these observations with respect to the interplay between molecular gas, star formation and AGN, and illustrate how one can apply our local knowledge to characterizing star formation and gas properties in high-z galaxies.
 Prof. Nanyao Lu is a Senior Scientist working at CAS South American Center for Astronomy (CASSACA) since 2016. Prof. Lu obtained his Ph.D. in Astrophysics from Cornell University in 1993. Before joining CASSACA, he worked as a postdoctoral research fellow at Jet Propulsion Laboratory (JPL) from 1993 to 1995 and a Staff Scientist at Infrared Processing and Analysis Center (IPAC) from 1996 to 2015. While at JPL, Prof. Lu also worked as an instrument scientist for Infrared Space Observatory (ISO) (1996-2001), Spitzer (2001-2007), and Herschel (2007-2015). Prof. Lu’s research has been focused on the interstellar medium properties and star formation process in galaxies near and far, using optical, infrared, and radio observational data.
