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.

Ke-Jung "Ken" Chen

  • Education and Positions:

    • EACOA Fellow, NAOJ and ASIAA (2015~2018)

    • IAU-Gruber Fellow, Department of Astronomy and Astrophysics, UC Santa Cruz, USA (2013~2015)

    • Johnston Fellow, Department of Physics, University of Minnesota, USA (2012~2013)

    • KITP Graduate Fellow, Kavli Institute for Theoretical Physics, USA (2012)

    • Physics PhD, University of Minnesota (2013)

  • Research Interests: 

    • ​My research interest in computational astrophysics focuses on modeling the supernovae explosions and their cosmological impact by using multidimensional hydrodynamics/radiation/cosmological simulations. These supernovae are from the death of massive stars triggered by core-collapse, magnetar, pair-instability, and general-relativity instability
