26/12/2019-Galaxy assembly across cosmic time

SHAO Astrophysics Colloquium

Title: Galaxy assembly across cosmic time

Speaker: Yingjie Peng (KIAA)

Time: 3:00 pm, December 26th (Thursday)

Location: Lecture Hall, 3rd floor

Abstract: 

 

I will discuss galaxy assembly across cosmic time in four key aspects: star formation, quenching, stellar mass function evolution and galaxy-halo connection, in both observation and theory. I will show new evidences from multi-wavelength observations from optical to radio that demonstrate the detailed quenching process of galaxies, which provides stringent constraint on the physical mechanism of quenching. These new observational evidences are then compared to theoretic predictions and hydrodynamical simulations. I will discuss the great success and failure of simulations in reproducing observations, which put new constraints on the AGN feedback physics. If time allows, I will also discuss plans to explore galaxy assembly with forthcoming major observing facilities.
