Merger between two stars led to iconic supernova -- Simulations suggest that two stars came together to form a blue supergiant, which subsequently exploded
A supernova in a nearby galaxy may have originated from an explosion of a blue supergiant formed by the merger of two stars, simulations by RIKEN astrophysicists suggest1. The asymmetric nature of thi...more
The rapid development of AI is driven by technology called deep learning. However, no one knows yet why AI with high performance can be achieved through deep learning. We asked Dr. Masato Taki, who is...more

Modeling the insides of a neutron star -- Improvements to a model for the inside of a neutron star make it applicable to neutron star mergers
RIKEN astrophysicists have developed an improved model for the interior structure of neutron stars that agrees well with observations. Unlike previous models, it can be extended to consider what happe...more
Strong lensing of the galaxy, which can be seen as arc-like features, is a powerful probe of the small-scale DM halos. The populations of small-scale DM halo give us hints about its particle propertie...more

Many people think of experiments when they hear the words “biological research.” However, Jeffrey Fawcett researches the evolution of species by analyzing genetic information using computers. Below, w...more
On January 28th, iTHEMS member Don Warren co-hosted a workshop on Communication for Interdisciplinary Collaboration. The goals of this workshop were (1) to learn how to communicate with people who do...more
Interdisciplinary workshop "Present and Future of the Quantum Computing (QC)" hosted by MEXT and sponsored by iTHEMS and CEMS was held on Jan.29, 2020 at RIKEN Suzuki Umetaro Hall. There were more tha...more
As ABBL/iTHEMS seminars, Dr. Hajime SOTANI gave a talk about "Neutron stars and nuclear saturation parameters" on 24th January. So far, many equations of state (EOSs) for neutron star matter are propo...more
Hello. My name is Tomoki Ozawa. I am a senior research scientist at RIKEN iTHEMS. As of February, I am leaving iTHEMS and moving to Advanced Institute for Materials Science (AIMR) in Tohoku University...more
Search for gamma-ray signals from dark matter annihilations in extended dwarf spheroidal galaxies, article on the Astronomical Herald
The importance of the dark matter density distribution in target galaxies is discussed under realistic settings of the future gamma-ray experiment.
The iTHEMS Math seminar was held on 23 January, inviting Shu Nakamura from Gakushuin university. The title of the talk was “Semiclassical methods in mathematical quantum mechanics”. The topic was semi...more
How deep can an apple fall into the horizon of a black hole? Of course, in the case of a classic black hole, the apple reaches the center. However, the real world is described by quantum theory, and b...more
