The J-PARC muon g-2/EDM experimental group, which includes Professor Toru Iijima, Designated Lecturer Kazuhito Suzuki, Associate Professor Kenji Inami, and graduate students Kazuji Sumi, Koichi Ueda, and Ayaka Kondo, has successfully cooled and accelerated positively charged muons for the first time in the world. This achievement marks a major step toward launching an ultra-precise verification of the Standard Model. Additionally, a completely new imaging technique using accelerated muons is being considered for various applications, including muon microscopy and interdisciplinary research …

Abstract Our groups, led by Associate Professor Kazuhiro Nakazawa at Nagoya University/KMI and first-year Ph.D. student Yuki Omiya at the Graduate School of Science, in collaboration with a research team led by Project Researcher Kohei Kurahara at the Mizusawa VLBI Observatory, National Astronomical Observatory of Japan (NAOJ), discovered an extended radio emission in the Hydra cluster, about 150 million light-years away. Galaxy clusters are the largest self-gravitating objects in the Universe, surrounded by hot gas, magnetic fields, and cosmic rays …

On February 20, 2024, the Belle II experiment resumed data acquisition for physics measurements. Belle II is a particle physics experiment designed to investigate the properties of particles, such as B mesons, produced by the SuperKEKB accelerator. This research aims to study new physical phenomena that are crucial for understanding the mechanisms behind the creation of the universe. Operations were suspended for about 18 months starting in the summer of 2022, and major improvements were made to both the accelerator …

The Division for Theoretical Studies in KMI seeks to fill a full-time, non-tenure-track, designated Assistant Professor position. For more details, please read PDF.

The X-ray astronomy satellite XRISM, primarily developed by JAXA Institute of Space and Astronautical Science (ISAS), is set to launch on August 26th September 7th (Thursday). Equipped with the world’s most advanced X-ray spectroscopic capability, the XRISM satellite will shed light on the dynamic nature of the universe. It will unveil the velocity, turbulence, and other motions of high-temperature plasma in high-energy celestial bodies like galaxy clusters and black holes with unparalleled precision. The Nagoya University group, led by Assoc. …

Abstract Our group led by Associate Professor Kazuhiro Nakazawa at Nagoya University/KMI, and doctoral course student Yuki Omiya at the Graduate School of Science, in collaboration with the National Astronomical Observatory of Japan, Tokyo University of Science, Hiroshima University, Saitama University, JAXA Institute of Space and Astronautical Science, Tokyo Metropolitan University, Netherlands Institute for Space Sciences, and Toho University, succeeded in estimating the length, width, depth, and merging velocity of the shock wave just born in the nearby merging galaxy …

The values of fundamental constants of nature, dubbed as physical constants, might be affected by new elementary particles and unknown forces of nature, according to a study by an international group of researchers that includes Designated Assistant Professor Teppei Kitahara at KMI and Institute for Advanced Research, Nagoya University and at IPNS, KEK (cross appointment). The findings were published in the journal Physical Review Letters. Scientists continuously strive to develop and refine theories that explain the world and the universe …

The FASER collaboration (ForwArd Search ExpeRiment at the LHC; FASER) reported that the FASER detector has achieved observations accurate enough to detect the presence of neutrinos produced at the collider. Established in 2017, the FASER experiment aims to discover elementary particles that could contribute to a better understanding of dark matter, as well as to study neutrinos in the unexplored high-energy region to explore the unknown physical laws behind the Standard Model of elementary particles. The experiment focuses on secondary …
