credit: Reiko Matsushita (Nagoya University)   An international research group led by Associate Professor Hironao Miyatake at KMI, Nagoya University, Assistant Professor Yuichi Harikane and Professor Masami Ouchi at the Institute for Cosmic Ray Research, University of Tokyo, and their colleagues, have successfully detected the presence of dark matter around galaxies in the distant universe approximately 12 billion light years ago for the first time by combining data from the Hyper Suprime-Cam (HSC) camera on the Subaru Telescope and ESA/NASA’s …


Scientists from the international XENON collaboration, an international experimental group including the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI), Nagoya University; the Institute for Space-Earth Environmental Research (ISEE), Nagoya University; the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), The University of Tokyo; the Institute for Cosmic Ray Research (ICRR), The University of Tokyo; and the Graduate School of Science, Kobe University, announced today the first results from XENONnT, the latest detector …


Dr. Takeshi Kaneko is newly assigned to KMI as a cross-appointed lecturer. Welcome! He belongs to KEK Theory Center and he is studying lattice QCD.  KEK Theory Center and KMI discussed cross-appointments in both directions.  Dr. Kaneko is assigned to KMI as a lecturer, and Dr. Teppei Kitahara in KMI is also assigned as an assistant professor in KEK Theory Center.  We hope that this will strengthen the relationship between KEK Theory Center and KMI.   Homepage of KEK Theory …


On Friday, January 14, 2022, Nagoya University and KMI hosted a special event entitled “The 50th Anniversary of the Kobayashi-Maskawa Theory – In Memory of Maskawa-san”. (*) 2022 marks the 50th anniversary of the proposal of the Kobayashi-Maskawa theory, for which Professors Makoto Kobayashi and Toshihide Maskawa were awarded the Nobel Prize. To reflect on their achievements and to remember Prof. Toshihide Maskawa, who passed away in July of 2021, we have planned the event that gives an overview of …


KMI Associate Professors Hironao Miyatake and Shingo Kazama were selected for the Fusion Oriented REsearch for disruptive Science and Technology (FOREST) program by the Japan Science and Technology Agency (JST). FOREST aims to create seeds that lead to innovation through diversity and interdisciplinary research without setting specific projects or short-term goals, this program provides long-term support for unrestricted, challenging, interdisciplinary, and diverse research not bound by the existing frameworks, for the period of seven years in principle (up to 10 …


ForwArd Search ExpeRiment at the LHC (FASER), an international collaboration involving KMI’s Toshiyuki Nakano, Mitsuhiro Nakamura, Hiroki Rokujo, and Osamu Sato has successfully observed neutrino reaction candidates from the LHC, the world’s highest energy collider. This result shows that the FASER experiment is indeed useful in the study of TeV-scale neutrinos. This achievement uses the nuclear emulsion technology developed by Nagoya University’s F Lab, which highlights the high mobility in equipment installation and development. The results of this research were …


The first “KMI Flash” hybrid – face-to-face and remote – conference was held on Wednesday, July 28, 2021. Due to the COVID19 disaster, students and young researchers have fewer opportunities to interact and present their research across fields and generations. Therefore, KMI Flash, a research presentation event for students and young researchers in the field of elementary particles and cosmology/astrophysics at Nagoya University, was organized by volunteers from KMI young researchers. There are different approaches and specialties in astro/particle physics, …


KMI welcomed Dr. Nodoka Yamanaka, as a new KMI’s assistant professor. Dr. Yamanaka joined the Division of Theoretical Studies at KMI on September 1st, 2021. Welcome, Yamanaka-san!  Visit his member page for his profile. 


It is with great sadness that KMI shares the news of the passing of Toshihide Maskawa, Professor Emeritus of Nagoya University, on July 23, 2021. Maskawa was awarded the Nobel Prize in Physics in 2008, then he became the first Director of the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI) from 2010 to 2018. Afterwards, Maskawa continued to mentor KMI from a broad perspective, as Director Emeritus. Remembering his inspiring words, we continue to explore basic …
