Professor Motohara, Kentaro

Research Field

  • Infrared Astronomy, Optical-Infrared Instrumentation, Galaxy Formation and Evolution

Brief Introduction of Research

  • We are working on instrumentation in the near-infrared wavelength (1-2.5micron), as well as the study of galaxy formation and evolution through observations of both nearby starbursts and distant galaxies beyond redshift of one.
    The major ongoing projects are ; Development of a NIR imager and multi-object spectrograph SWIMS and its operation, NIR medium-band filter survey to probe evolution of galaxies at the cosmic noon, hydrogen Pa-alpha observation of nearby U/LIRGs, and development of a NIR integral-field unit by high-precision machining technology.
