个人简介

祝伟于2017年博士毕业于美国俄亥俄州立大学,之后在加拿大多伦多大学从事博士后研究工作,并于2021年春季加入清华天文系。祝伟的主要研究方向是系外行星。通过结合微引力透镜法、掩食法、视向速度法和天体测量法等不同的探测方法,他系统地搜寻和认证那些围绕其他恒星绕转的行星,研究这些行星的统计分布和系统构型,并基于此来限制行星形成和演化的理论模型。除此之外,祝伟对致密天体的搜寻也很感兴趣。理论工作表明,能产生可探测引力波的双黑洞系统只占所有恒星质量黑洞的很小一部分。对无法用引力波探测到的恒星级黑洞的研究对人们认识黑洞形成和分布具有重要意义。 Employment 2023.06 – Associate Professor (tenure-track), Department of Astronomy, Tsinghua University 2021.02 – 2023.06 Assistant Professor, Department of Astronomy, Tsinghua University 2017.09 – 2021.02 Postdoctoral Fellow, Senior Research Associate, Canadian Institute for Theoretical Astrophysics (CITA), University of Toronto, Canada Education 2013.08 – 2017.08 PhD in Astronomy, The Ohio State University, Columbus, USA Thesis: Microlens mass determinations from space-based parallax Advisor: Prof. Andrew Gould 2009.09 – 2013.07 BS in Astronomy, Peking University, Beijing, China
