ABOUT US

The Cosmic Explosion Group
 

We are a small research group in Academia Sinica Institute of Astronomy and Astrophysics (ASIAA). Our research interests in computational and theoretical astrophysics focus on the explosive phenomena in the Universe. The formation and evolution of these explosive astrophysical objects  in the universe is a highly significant area of contemporary astrophysical research.

 Our research topics include stellar evolution of massive stars, supernova modeling, physics of compact objects, formation of the first stars and galaxies, etc.  We use sophisticated numerical simulations to study the physics behind these fascinating objects and have been constantly collaborating with other leading scientists around the world such as Stan WoosleyAlex HegerVolker Bromm etc. Thanks so much for visiting our website and wish you have a pleasant day.

    • Physics PhD, University of Minnesota (2013)

  • Research Interests: 
    ​I am deeply passionate about computational and theoretical astrophysics, particularly the life cycles and explosive deaths of the massive stars. I lead a team of students and early-career researchers employing advanced numerical simulations to study how the massive stars formed, evolved, and ended as supernovae or black holes, and how their feedback shaped the universe across cosmic time.
