Starting this week, as you can see, we will try new format of the newsletter. The style will be compatible with the new web site we are working on. There are still few loose ends we need to tie up, but we will appreciate your feed back.
Supernova explosion in K-computer
An interview of Dr. Tomoya Takiwaki was recently published in "The World of Numerical Science" (vol.9, Oct. 17, 2014). Tomoya is an iTHES associate in ithes-phys team. For the first time in the world, he together with K. Kotake (Fukuoka) and Y. Suwa (Kyoto) could show successful core-collapsed supernova explosion on the basis of the 3D simulation with the K-computer in 2011.
The neutrino heating mechanism and the convection mechanism are the key factors for the successful explosion.For more details, see the article (in Japanese).
Niels Bohr, one of the founding farthers of quantum physics, visited Japan in the spring of 1937 by the invitation of Dr. Yoshio Nishina, who used to study under Bohr in Copenhagen. Then, Bohr brought a 8mm movie camera with him and filmed his journey on the exotic land. Later, in 1973, a copy of the film was brought by Aage Bohr, Niels Bohr's son and also a Nobel Laureate, to Nishina Memorial Foundation. The film was then reviewed by Prof. Shin-ichiro Tomonaga as a part of the talk article of the magazine "SHIZEN." After that, somehow the film had been misplaced and it has not been shown.
Recently, Dr. Yasushige Yano, special adviser to Nishina center and Trustee of Nishina Memorial Foundation recovered the film. The occasion of public showing first in 40 years was set on October 24th at RIBF Building, RIKEN Wako campus. The film was taken without audio track, so Prof. Yoich Nagashima from the Univesrsity of Copenhagen supplied commentaries as the film was shown. After the showing of the film, Prof. Hiroshi Ezawa, Prof. Emeritus of Gakushuin university, gave a lecture about Dr. Nishina's visit to Niels Bohr's institute in Copenhagen.
This was a very unique occasion to experience firsthand the legacy of the creator of quantum physics, Bohr and also Dr. Nishina who introduced the new physics to Japan.
Person of the Week
I am Yuto Teraki, a member of Astrophysical Big Bang Laboratory.My main interest is in astrophysics, especially high energy astrophysical phenomena.I received PhD from university of Osaka 2014 (this March) and started SPDR fellow from this April.
Recently I am studying particle acceleration and radiation from these particles in the context of the pulsar wind nebulae.This topic deeply connected with particle accelerator of electrons and laser physics.As just described, the communication with scientists in other field is very important for astrophysicists.So I am happy to join iTHES group.In addition, I like not only physics but also whole science.I am looking forward to having exciting discussion with you.
Apart from science, I like sports, such as baseball, rugby football, etc..My hobby is riding motorcycle.
