Multi-wavelength imaging observations of STEVE at Athabasca, Canada

Drs. Sneha Yadav, Kazuo Shiokawa, and Yuichi Otsuka of Division for Ionospheric and Magnetospheric Research report the first multi-wavelength imaging observations of STEVE, in collaboration with Athabasca University and University of Saskatchewan, Canada.


ISEE developed one of the most accurate solar storm arrival-time prediction systems

The new solar storm prediction system developed by ISEE achieved the most accurate prediction for solar storm arrival-times in the world.

ISEE team developed the first physics-based method that can predict imminent large solar flares

The research team led by Professor Kanya Kusano (Director of ISEE, Nagoya University) succeeded in developing the first physics-based model that can accurately predict the location and scale of imminent large solar flares.


Large transverse asymmetry observed in neutral pion production in polarized proton-proton collisions
- New research deepens mystery of particle generation in proton collision -

A group of researchers including scientists from the RIKEN Nishina Center for Accelerator-Based Science, University of Tokyo, Nagoya University, and the Japan Atomic Energy Agency (JAEA) used the spin-polarized Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in the United States to show that, in polarized proton-proton collisions, neutral pions emitted in the very forward area of collisions—where direct interactions involving quarks and gluons are not applicable—still have a large degree of left-right asymmetry.


Observation of Excess Events in the XENON1T Dark Matter Experiment

Scientists from the international XENON collaboration, involving Professor. Yoshitaka Itow (KMI, ISEE), Associate Professor. Masaki Yamashita (ISEE), YLC Assistant Professor Shingo Kazama (KMI, IAR), announced that data from their XENON1T, the world's most sensitive dark matter experiment, show a surprising excess of events.


Prototype CTA Telescope Detects Gamma Rays from the Crab Nebula

A prototype telescope with the Schwarzschild-Couder optical system, developed for the Cherenkov Telescope Array (CTA) project, successfully detected very-high-energy gamma rays from the Crab Nebula.


A prototype focal-plane camera of the Small-sized Telescope of the Cherenkov Telescope Array project achieves its first light with silicon photosensors


Development of a new space weather forecasting system using interplanetary scintillation observations

A new space weather forecasting system has been developed using the ground based interplanetary scintillation observations of ISEE and a global magnetohydrodynamic simulation of the inner heliosphere.


Mid-latitude SuperDARN review paper has been published

The mid-latitude SuperDARN review paper titled ”Review of the accomplishments of Mid-latitude Super Dual Auroral Radar Network (SuperDARN) HF Radars” has been published in Progress in Earth and Planetary Science journal.


FOXSI-3 Succeeded in Focusing Imaging Spectroscopic Observation in Soft X-rays from the Sun for the First Time in the World!

On September 7, 2018 MDT (September 8 in Japan time), an international team from Nagoya University, National Astronomical Observatory of Japan, Kavli IPMU at University of Tokyo, JAXA institute of Space and Astronautical Science, Tokyo University of Science, Minnesota University, University of California at Berkeley and NASA performed the thrid flight of the Focusing Optics Solar X-ray Imager (FOXSI-3) sounding rocket payload for solar X-ray observations from White Sands, New Mexico, USA. A high-speed X-ray CMOS camera developed in Japan was onboard, and the CMOS camera sucessfully performed imaging spectroscopy of X-rays from the Sun in a 0.5-5 keV range for the first time. We expect the FOXSI-3 observation will reveal detailed physical conditions of the solar corona and coronal small scale events.

Complicated variations of the upper atmosphere near a breakup aurora - Eos Research Spotlight

How does the upper atmosphere change by auroral breakup, this is an outstanding question in the Magnetosphere-Ionosphere-Thermosphere coupling study.  We published a paper in JGR Space Physics analyzing data taken from a sounding rocket and ground-based instruments.  The paper was chosen as an article of Eos Research Spotlight. 


Identification of generation of plasma waves in geospace.

The ISEE team identified the generation process of plasma waves in geospace by integrated studies on the satellite data analysis and supercomputer simulation.


A joint observation by solar observing satellites Hinode and IRIS quantitatively explores the formation of the solar chromosphere


The distribution of coronal holes over the last 40 years

In a collaboration with Chubu University, we developed an automated prediction technique for coronal holes using potential magnetic field extrapolation in the solar corona using synoptic magnetogram data obtained at Kitt Peak National Solar Observatory (USA). 


A Prototype of the Cherenkov Telescope Array Achieves First Light with Cosmic-Ray Air Showers

A prototype telescope and a camera of the Cherenkov Telescope Array successfully recorded cosmic-ray air-shower images. The prototypes were also inaugurated at the Paris Observatory.
