SHAO Astrophysics Colloquia

Title: Supernova Zoo: Obervations and Theories

Speaker: Xiaofeng Wang(Tsinghua University)

Time: 3 PM, Apr. 20th (Thursday)

Abstract:

Supernovae (SNe) represent the final, explosive stage of certain types of stars,  playing important roles in diverse aspects of astrophysics, especially in observational cosmology. Large surveys launched in recent years lead to discovery of numerous such explosions, including some new types and subtypes that were unknown before. I will review the physical connections between different types of SNe and different types of stars. Some interesting results on constraints of progenitors and explosion physics of type Ia SNe and core collapse SNe from our own programs (i.e., TNTS and PTSS) will be also highlighted.

Seminar talk

Titile: Impact of molecular clouds on galactic disk clumpiness

Speaker: Guangxing Li (Universitats-Sternwarte Munchen)

Time: 14:00, Tuesday, April 18
Location: Room 303, 3rd floor

 Abstract: Different from the Milky Way, disks of gas-rich galaxies are clumpy. It remains a mystery why they are clumpy and how star formation occurs in these clumps. Molecular clouds constitute a significant fraction of the total mass of galactic disks, and they play important roles in disk dynamics. I will present some recent observational results, and discuss how dynamics of molecular clouds on pc scale influences the dynamics of galactic disk at kpc scale and lead to the formation of giant clumps.
