A8 Masaki ANDO Department of Physics http://granite.phys.s.u-tokyo.ac.jp/en ando[at]phys.s.u-tokyo.ac.jp Our main target is to expand a new field of gravitational-wave astronomy. For it, we are participating as a main institute to a KAGRA project and constructing a large-scale cryogenic laser interferometer for gravitational-wave observation at Kamioka, Gifu. We are also developing key components for DECIGO, a space gravitational-wave telescope. In addition, we are working for experimental tests of relativity, and quantum measurements using laser interferometers.

A8 Kiwamu IZUMI The Institute of Space and Astronautical Science https://researchmap.jp/kiwamu-izumi?lang=en izumi.kiwamu[at]jaxa.jp A major goal of our group is an achievement of gravitational wave observations from space and carrying out astronomical research based on the observations. Utilizing the inherently quiet environment in space, we aim at observing new classes of gravitational wave phenomena including background radiation generated in the very early universe. We carry out research and development activities in ground laboratory and simultaneously peruse the realization of high-precision formation flying mission for technology demonstration in orbit.
A8 Akito KUSAKA Department of Physics https://www.cmb.phys.s.u-tokyo.ac.jp/en/ akusaka[at]phys.s.u-tokyo.ac.jp Why and how did our universe begin? How has it evolved? These are the key questions of our research. We explore these fundamental questions primarily through observing cosmic microwave background (CMB), the light from the very beginning of the universe. Through CMB, we study not only the fundamental nature of the universe, but also particle physics as well, such as the nature of neutrinos and unknown particles. Our approach is that of experimental physics, and our research entails development of cutting edge technologies such as those using superconducting instrumentation, and low-temperature and microwave engineering.

A8 Tomotake MATSUMURA Kavli Institute for the Physics and Mathematics of the Universe http://member.ipmu.jp/tomotake.matsumura/ipmucmb.html tomotake.matsumura[at]ipmu.jp We study the physics of early universe using the measurement of cosmic microwave background (CMB) polarization. The theory of cosmic inflation can be tested by measuring the B-mode pattern in the CMB polarization experimentally. We are active member of LiteBIRD, the post ESA Planck satellite, to measure the CMB B-mode polarization. We develop observational hardware (polarization modulator), study systematics effects, develop new calibration strategy and prepare for the data analysis. We also participate POLARBEAR/Simons Array, and PILOT in development and characterization of hardware, operation, calibration and data analysis.
A8 Osamu MIYAKAWA Institute for Cosmic Ray Research https://www.icrr.u-tokyo.ac.jp/gr/GWPOHPe/index-e.html miyakawa[at]icrr.u-tokyo.ac.jp We develop fundamental technologies for the large-scale cryogenic gravitational wave detector KAGRA, and improve the sensitivity of KAGRA. Our main research topics are the development of high-power lasers, input/output optics, interferometer control systems, data acquisition systems, and interferometer simulation. We establish detector commissioning and observation to detect gravitational waves in Japan, and aim to be a central gravitational wave observatory in the Asian region.
A8 Shinji MIYOKI Institute for Cosmic Ray Research https://www.icrr.u-tokyo.ac.jp/gr/GWPOHPe/index-e.html miyoki_[at]_icrr.u-tokyo.ac.jp I am working toward the direct detection of gravitational waves that is predicted by general theory of relativity. We have finished research and developments for over 20 years by using proto-type laser interferometers, and then we are now developing "KAGRA" Large-scale Cryogenic laser interferometer Telescope. I would like to detect gravitational waves and to start gravitational wave astronomy as one of GW detectors as LIGO, VIRGO and GEO600 in the world. In addition to gravitational wave research, I am trying to observe macroscopic quantum mechanics by using ultra-precise length measurement technique.
A8 Shigetaka MORIYAMA Institute for Cosmic Ray Research http://www-sk.icrr.u-tokyo.ac.jp/ moriyama[at]icrr.u-tokyo.ac.jp My fields of interest include dark matter, axions, neutrino physics, and proton decay. My research comprises of two experimental approaches. The first approach involves the use of a liquid xenon target that is sensitive to an energy scale ranging from sub-keV to MeV. The XENONnT detector with ~10 ton of liquid xenon is used to discover dark matter particle in the Universe with the world best sensitivity. The second approach involves the use of Super-Kamiokande. The hierarchy of neutrino masses and CP violation in the lepton sector may be crucial for understanding the existence of matter in the Universe, and an observation of proton decay clearly indicates a large framework of particle physics. We are working to realize a much larger detector, the Hyper-Kamiokande.

A8 Masami OUCHI Institute for Cosmic Ray Research http://cos.icrr.u-tokyo.ac.jp/16.html ouchims[at]icrr.u-tokyo.ac.jp We study the early universe by observations. Armed with the state-of-the art telescopes such as Subaru and Hubble (+ALMA), we aim to push the today's observational frontier towards the very high redshift universe that no one has ever seen by observations. Our goal is understanding physical processes of galaxy formation at the early stage and the relevant event of cosmic reionization.

We are planning to make observations simultaneously with compound-eye optical telescopes deployed at four sites on Hawaii Island, which are scaled up from the Ashra-1 detector units and the world largest astronomical tau neutrino telescope, i.e. Ashra Neutrino Telescope Array (Ashra NTA). We are pioneering full-fledged particle astronomy with PeV-EeV neutrinos and TeV-PeV gamma-rays by clearly identifying positions of the unrevealed source objects.

A8 ＊＃ Masato TAKITA Institute for Cosmic Ray Research http://www.icrr.u-tokyo.ac.jp/em/index.html takita[at]icrr.u-tokyo.ac.jp We set up a large (37000-m**2) air shower arrays at Yangbajing in Tibet，China. We aim at observing multi-TeV cosmic gamma rays from astoronomical point sources such as AGN (active galactic nuclei), supernova remnants, GRBs (galactic gamma-ray bursts), etc. At the same time, we are tryingto disentangle the old enigmas in cosmic-ray physics: the origin of cosmic rays and their acceleration mecanism and the chemical composition of the primary cosmic rays. Those who find research fun in discussing with colleagues and in cooperative work (detector construction, for example) maybe more suitable than those who like to do physics by themselves. Normally, we do data analysis and development of new detectors at ICRR (Institute for Cosmic Ray Research) at Kashiwa.
A8 Takashi UCHIYAMA Institute for Cosmic Ray Research http://www.icrr.u-tokyo.ac.jp/gr/GWPOHPe/index-e.html uchiyama[at]icrr.u-tokyo.ac.jp Detection of gravitational wave which is predicted in Einstein's general theory of relativity and establishment of gravitational wave astronomy.
A8 Mark VAGINS Kavli Institute for the Physics and Mathematics of the Universe https://db.ipmu.jp/member/personal/27en.html mark.vagins[at]ipmu.jp My research is focused on developing new methods of observing neutrinos, both through the enhancement of existing detectors like Super-Kamiokande (Super-K) and via the design and construction of future facilities like Hyper-Kamiokande. One of my main goals is to measure, for the first time, the diffuse supernova neutrino background (DSNB), often called the “relic” supernova neutrinos. Adding water-soluble gadolinium to Super-K - an idea I co-invented - should allow us to detect these relic neutrinos without having to build an all-new experiment. Enhancing Super-K in this manner will also make possible other new physics, including high-statistics reactor antineutrino oscillation studies, as well as improve studies of neutrino oscillations and proton decay searches.
A8 Hiroya YAMAGUCHI The Institute of Space and Astronautical Science https://yamaguchi-astro.isas.jaxa.jp/index.html yamaguchi[at]astro.isas.jaxa.jp My research interest is on high-energy astronomical phenomena, such as those observed in stellar flares, supernova remnants, and galaxy clusters. Observations of these objects using artificial satellites allow us to reveal how the Universe has evolved to date. I'm also developing facilities enabling "laboratory astrophysics" to reproduce radiation processes relevant to the high-energy astronomical objects on ground. In my main institute JAXA/ISAS, I'm involved in the XRISM project as Deputy Project Scientist, responsible for the science lead. Before coming back to ISAS last year, I was in the US for 7.5 years.

With observational study with Suzaku and Hitomi observatory, I promote to realize ultra-high energy resolution spectroscopy in coming missions, Athena, DIOS etc. Also novel detector development like TES and other kind of non-resistive calorimeters is underway.
