Title: Initiation and Energy Release of Solar Coronal Mass Ejections and Relevant Solar Radio Bursts
Speaker:
Yao Chen (Institute of Space Sciences, Shandong University Weihai)

Time: 3 pm, October 18(Thursday)

Location: Lecture Hall, 3rd floor


Abstract: The current cosmology research has entered a paradigm of precision cosmology on the large scale, where efforts are made primarily to improve our measurements of the cosmological parameters. On the other hand, the small scale structure of the universe emerges as an active field that encompasses rich phenomenology and is tightly connected to the properties of galaxies, as well as to the nature of dark matter. In this talk, I will introduce a series of works that we have done to study the small scale structure of the universe in the dark matter component, taking advantage of a set of high resolution numerical simulations. I will show you how we can identify and model the smallest dark matter structures resolved by simulations in the framework of hierarchical structure formation, and how these results can be confronted with observations to shed light on the nature of dark matter as well as on galaxy formation processes.

The Astrophysics division is the main group engaged in astrophysical research at Shanghai Astronomical Observatory. Research areas include active galactic nuclei and high energy astrophysics, galaxy formation and evolution, cosmology and large scale structure, star clusters and the structure of the Milk Way, star formation, and planetary astrophysics. There are now 45 faculty members, 16 postdocs, and 65 graduate students in the division.

The Astrophysics division maintains close partnerships with many astronomical research institutes, including the joint Key laboratory of research in galaxies and cosmology of CAS with University of Science and Technology of China, the joint astrophysics center with Xiamen University. Members of the astrophysics division also participate in many international and domestic astronomical projects, including LAMOST, HXMT, FAST, the Sloan Digital Sky Survey IV, TMT, LSST, etc.
