【报告题目】Condensation and evolution of Halos and Boson stars
【摘要】The existence of dark matter has been widely accepted by modern physics and astronomy. Therefore, research on the nature of dark matter has become a very important topic. Among all the candidate particles, axion is a very promising one . This talk focuses on the dynamical formation and growth of two very important forms of axion, halos and boson stars in a collection of different models, including self-gravity, attractive and repulsive self-interactions [2, 3]. These results have applications to future terrestrial, astrophysical, and cosmological observations searching for new types of bosons across a wide range of scales.
