2024年11月27日， 周三15:30-17:00紫金港西区海纳苑8幢324    Tracing the baryonic cycle in and around galaxies using radiation hydrodynamic simulations李辉（清华大学）Abstract：The cycling of gas in and around galaxies plays a critical role in their evolution. For galaxies smaller than the Milky Way, the complex baryonic cycle is believed to be driven by feedback from young stars. To fully understand this highly non-linear process, it is necessary to employ multi-scale, multi-physics simulations. In this talk, I will first provide a brief overview of the current state of galaxy formatio...

2024年11月21日， 周四15:30-17:00紫金港西区海纳苑8幢324Numerical Simulations of Dynamical Processes on Various Astrophysical Scales刘尚飞（中山大学）Abstract：Similar dynamical processes occur across different context in astrophysical studies, ranging from planets to black holes. Due to the nonlinear nature of these processes, numerical simulations serve as powerful tools for investigating their roles in the evolution of astrophysical systems. In this talk, I will present our hydrodynamic and N-body simulations of relevant processes. In particular, I will discuss some observational implications...

2024年11月14日，周四15:30-17:00紫金港西区海纳苑8幢324New Frontiers of Dark Matter Halo (暗物质晕的新前沿）韩家信（上海交通大学）Abstract：Current theoretical understandings of the nonlinear structure formation and galaxy formation processes are largely built upon a central concept that dark matter in the Universe are mostly contained in virialized clumps called dark matter halos, with the boundary of a halo described by its virial radius. However, the growth of a halo means it is inevitably surrounded by a non-virialized envelope of freshly accreted material. Failing to account for this envelo...
