Introduction of Research
I have investigated to make clear how galaxies have evolved from a viewpoint of interstellar gas and star formation mainly through observations with radio telescopes. Galaxies are assemblies of stars and interstellar medium, and the Milky Way is one of examples. The shape of galaxies is various, for example, there are spiral galaxies such as the Milky Way or the neighboring Andromeda galaxy, while there are galaxies whose shape is elliptical or irregular. Properties of galaxies located in dense regions are different from those of isolated galaxies. It is important to make clear how such variety results from, in order to understand galaxy formation and evolution. I have observationally investigated distributions, dynamics, physical properties of interstellar gas, which is material of stars, and relation among them and star formation activity in nearby galaxies. In recent years, I have engaged in a project that imaged many nearby galaxies in molecular gas tracer with the Nobeyama 45-m radio telescope, “CO multi-line imaging of nearby galaxies” (COMING). (see image “CO images of 147 nearby galaxies taken in COMING project”)
I have also an interest in development of telescopes and observational instruments. I developed the wide bandwidth radio spectrometers settled on the 45-m telescope. I engaged in improvement and operation of the Tomakomai 11-m radio telescope, and developed an automatic remote operation system of the telescope. (see photo “Tomakomai 11-m radio telescope”) In recent years, I have joined a project to construct terahertz telescopes in the Antarctica.
I come from Osaka.
