Person of the week

Jin Matsumoto



From the Office

The office of iTHES assistant, Ms.Chikako Oota is situated at the first floor of the main research building, room # 159. The extension number is 3185. She will be at the office from 10 a.m. to 16 p.m. except on Wednesday.


On Nov. 18th, the work by Dr. Tomoya Takiwaki in ithes-phys team and his collaborators about the mechanism of supernovae explosion will be featured in the "Science View". Science View is provided as a TV program of "NHK World", that is international broadcasting service for foreign countries. Unfortunately it is difficult to watch that from Japan. Subscription with some specified Cable TV company is necessary but see http://www3.nhk.or.jp/nhkworld/english/tv/scienceview/archive201411121800.html .

Person of the Week

Hi, my name is Jin Matsumoto. I am a member of Astrophysical Big Bang Laboratory. After I obtained my Ph.D. degree in Astrophysics at Kyoto University in 2012, I moved to the National Astronomical Observatory of Japan. Then I am working as a postdoc researcher at RIKEN from September 2013.

My research interest is the dynamical evolution of astrophysical jets and outflows. In addition, I am also very interested in the magnetohydrodynamic (MHD) phenomena in compact objects, such as supernovae, gamma-ray bursts and magnetars.

One of the most important and oldest problem in astrophysics is the evolution of jets which are collimated bipolar outflows from gravitationally bounded objects. Gaseous material, energy and angular momentum are supplied from the central objects into the surrounding environment by jets. It is important to study the interaction between the jet and surrounding medium not only for the dynamical evolution of the jet itself, but also for the surrounding medium.

In my current project at RIKEN, I am investigating the dynamics and stability of the relativistic jet through MHD simulations in the context of the gamma-ray burst. I am very happy if I can communicate with iTHES members in order to get wide range of knowledge. Because they are necessary in order to unveil the physical mechanism of the gamma-ray burst.
