SHAO Astrophysics Colloquia 

Title: Star Formation And Gas In Nearby Galaxies 

Speaker:  施勇（教授，南京学）

Time: Thursday, 3:00pm, December 25th

Location: Lecture Hall, 3rd floor

Abstract: Star formation is a key physical process of baryonic matters, and plays crucial  roles in driving galaxy formation and evolution. The observed relationship between star formation rates and gas masses offers a powerful empirical way  in understanding star formation and is widely invoked in numerical simulations of galaxy formation and evolution. In the past decade, the rich  

multi-wavelength data of nearby galaxies have enabled well characterizations of  this gas-SFR relationship. However, the majority of these works focuses on  studies of galaxies that are typical in the local universe but may be largely different from those in the early Universe. In this talk, I will represent our recent  works along with others’ that probe star formation in some extreme  

environments such as galaxy outer disks, extreme low metallicity galaxies, radio galaxies etc. All these works challenge the traditional SFR-gas relationship, implying that different physical mechanisms may play roles in star formation during galaxy evolution.
