SHAO Astrophysics Colloquium

Title: Gravitational waves and testing of gravity

Speaker: Wen zhao  (University of science and technology of China)

Time: 3:00 pm, Jan. 02th (Thursday)

Location: Lecture Hall, 3rd floor

Abstract: 

In this report, we introduce the basic principle and current situation of strong field test of general relativity by gravitational wave. The report is divided into three parts, the first part briefly introduces the theory of gravity and its test method; the second part introduces the characteristics of gravitational waves in various gravitational theories; the third part introduces how to use gravitational wave detection to test the model independence of gravitational theory.

Seminar talk

Title: 类星体成协吸收线研究

Speaker: 陈志福

Time: 9:30 am, Dec. 30 (Monday)

Location: room 303

 

Title: Some remarks on supernova-driven turbulence

Speaker: Miikka V?is?l? (ASIAA)

Time: 3:00 pm, December 30th (Monday).

Location: Large conference room, 3rd floor

Abstract: I will discuss my past work in the supernova-driven turbulence, and therefore galactic dynamo. Galactic dynamo consists of a combination of processes which are seen to regulate the generation and structure of galactic magnetic fields, but these are not well understood due to their non-linearity. I will discuss the topic from multiple angles. First, I will examine the effects of turbulent diffusion to the dynamo generation. Second, I will talk about direct numerical simulation of supernova driven turbulence itself. And third, I discuss how such simulations can be compared with the galactic foreground dust polarization observed by the Planck satellite.
