Talk Title: "Astrophysical Big Bangs"

Abstract:

Our group focuses on unveiling the many mysteries surrounding astrophysical explosive phenomena such as supernovae and gamma ray bursts from a theoretical point of view. Supernovae and gamma ray bursts are believed to be the most powerful explosions in our Universe, and yet very little about their explosion mechanisms is known to mankind. Members of our group use frontier physics in their daily routine to attack these problems in high-energy astrophysics. In many cases, we seek power from the quickly advancing supercomputing resources in Japan to make progress in our investigations. These 'astrophysical big bangs' continue to fascinate us with their unknown physics and puzzling astronomical phenomena (e.g. gravitational waves, r-process nucleosynthesis, particle acceleration, high-energy neutrinos, ultra high-energy cosmic rays, gamma-ray emission, etc), and they are commonly regarded as the most representative manifestations of the extreme Universe. Through our theoretical and computational endeavors, we strive to reveal the complete pictures of these violent explosions and provide state-of-the-art physical interpretations and predictions for future observations by the next-generation astronomical observatories. We are more than passionate to co-operate with fellow RIKEN researchers and all other interested groups in Japan and the globe, and together we will realize the Utopia for researchers in RIKEN. In this talk, I would like to introduce our research activities, together with short introduction of a new program in RIKEN "Interdisciplinary Theoretical and Mathematical Science Program (iTHEMS)"
