Research Field

  • Radio Astronomy
    Millimeter, Submillimeter and Terahertz instrumentations

Brief Introduction of Research

  • Research activities include developments of astronomical instruments in millimeter, submillimeter and terahertz observations, such as superconducting tunnel junction detectors, cryogenic readout electronics and observing technologies such as photon counting terahertz interferometry. Past development programs include instrumentation for NRO 45m, ASTE, ALMA and AKARI infrared satellites. Astronomical observing programs include cosmic microwave background, distant galaxies and clusters of galaxies as well as high-mass star-forming regions.
