Extragalactic radio astronomy

Research Subject

A study of active galaxies and high-redshift galaxies based on millimeter and submillimeter-wave observations and development of devices and equipments for observatioinal astronomy

Current Research

I am interested in the interstellar medium (ISM), which plays important roles on various active phenomena in galaxies, including starburst and active galactic nuclei. Observations at millimeter and submillimeter wavelengths, where emission lines from dense molecular medium and continuum radiation from cold dust components can be directly observed, are crutial for the understanding of ISM in galaxies. Therefore, we have conducted observational studies of ISM in various galaxies (from the Milky Way galaxy to the high-redshift galaxies in the early universe) in order to understand the nature of activities in galaxies and physical processes of galaxy formation and evolution. Atacama Submillimeter-wave Telescope Experiment (ASTE) 10 m dish is one of the key telescopes in my studies of ISM, and observing equipments and devices for ASTE have been developed in my labolatory. I am also involved with the related telescope projects, such as very small telescope (VST) and University of Tokyo Atacama Observatory (TAO).
