Hiroshi Matsuo

Hiroshi Matsuo is an Associate Professor at the Graduate University for Advanced Studies (SOKENDAI), affiliated with the Department of Astronomical Science under the School of Physical Sciences. He conducts research at the National Astronomical Observatory of Japan (NAOJ), focusing on advanced instrumentation for radio astronomy in millimeter, submillimeter, and terahertz bands.

His research interests center on Radio Astronomy and Terahertz Instrumentation, particularly the development of superconducting tunnel junction detectors, cryogenic readout electronics, and applications of intensity interferometry (Hanbury-Brown and Twiss method). His work enables high angular resolution imaging through photon bunching and delay time measurements, with proposed implementations in Antarctic and space-based interferometers.

The body of his recent publications reflects a strong trend in astronomical instrumentation and observational cosmology, especially using facilities like ALMA and JWST. His research spans detector physics, atmospheric transparency, and observations of distant galaxies and active galactic nuclei during the reionization epoch. Key themes include photon counting, aperture synthesis, and high-resolution mapping in submillimeter wavelengths.

• Terahertz and Far-Infrared Windows Opened at Dome A, Antarctica (Nature Astronomy, 2016)
• Detection of an oxygen emission line from a high-redshift galaxy (Science, 2016)
• Far-infrared intensity interferometry for high angular resolution imaging (SPIE, 2020)

Dr. Matsuo has been actively involved in advising research students and contributing to large-scale international collaborations. His projects often involve development of cutting-edge instrumentation and participation in major observational campaigns. While specific grants are not listed, his sustained publication record in top-tier journals suggests consistent funding support from national and international agencies.

He is a key member of the radio astronomy instrumentation team at NAOJ, contributing to both ground-based and space-based observational technologies. His work at Dome A in Antarctica highlights his involvement in extreme-environment astronomy and site characterization for future observatories.
