Understanding of physical properties for quantum many-body systems with strong interparticle interactions is one of key issues common to various subfields of physics. Such systems range from high-Tc s...続きを読む
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...続きを読む
The evolution of an exploding star begins more haphazardly than previously thought. Reference: Ferrand, G., Warren, D. C., Ono, M., Nagataki, S., et al.
Discovery of teraelectronvolt photons from gamma-ray bursts: A new window for exploring the most luminous explosions in the Universe
On January 14, 2019, TeV gamma rays (photons with energies a trillion times that of visible light) were clearly detected for the very first time from a gamma-ray burst (GRB; dubbed GRB 190114C) by the...続きを読む
Professor Takashi Tsuboi, Deputy Program Director of iTHEMS posted an article about RIKEN iTHEMS on Journal of the Mathematical Society of Japan. See the article in the November issue from the follow...続きを読む
The modelling work on supernova remnants made at ABBL & iTHEMS is highlighted in the latest image release from NASA's Chandra observatory
On October 17 the Chandra X-ray Observatory released an updated image of the supernova remnant known as Tycho. Supernova remnants, the aftermath of a stellar explosion, are key to understand how stars...続きを読む
Tracking down the origin of photons in gamma-ray bursts, article on RIKEN Research by Drs. S. Nagataki & D. Warren
The photons released by long gamma-ray bursts - the most powerful electromagnetic phenomena in the Universe - originate in the photosphere, the visible portion of the ‘relativistic jet’ emitted by exp...続きを読む
The waveforms of circadian cycles in bacteria, flies and mammals become increasingly jagged as the temperature rises, two RIKEN researchers have predicted. This finding is a step toward solving the my...続きを読む

Gilles Ferrand was highlighted in a recent article of RIKEN RESEARCH "Supernova remnants used to probe how star explosion took shape"
RIKEN astrophysicists have bridged the gap between studies of supernova and those of their remnants by using the output of a supernova model as the input for a model of a supernova remnant. This appro...続きを読む
Masaru Hongo was highlighted in a recent article of RIKEN RESEARCH "Describing the early Universe by simplifying complicated equations"
A powerful mathematical method for simplifying the analysis of highly complex systems has been extended by a RIKEN-led team. This will enhance its usefulness for researchers in a wide range of fields.
Masaru Hongo and Tatsuhiro Misumi were highlighted in a recent article of RIKEN RESEARCH "A smaller spin system yields its phase diagram"
By employing a clever approximation, three theoretical physicists at RIKEN (Masaru Hongo and Tatsuhiro Misumi of the iTHEMS and Yuya Tanizaki of the RIKEN BNL Research Center) have calculated the phas...続きを読む
