Abstract
The alpha disk model is widely used to describe the accretion disk structures around supermassive black holes, even though it cannot explain many observed properties of AGNs. I will describe our series of global 3D radiation MHD simulations of AGN accretion disks over a wide radial range with a variety of accretion rates. I will also discuss how the simulated disks are different from the standard disk model.
Biography
Yan-Fei Jiang received his Bachelor degree from Tsinghua University, BeiJing in 2008, and then got his Ph.D. from Princeton University, Princeton in 2013. He spent three years in CfA as an Einstein Fellow and three years in Santa Barbara as a KITP fellow before he joined CCA in 2019. Yan-Fei Jiang's research interest is broadly in computational astrophysics, such as accretion disks around compact objects, structures and evolutions of massive stars, cosmic ray transport and transients.
