Observation of infrared Galaxies at "Asuka"
2000 - 2000
Investigating Researcher (2)：
Infrared Galaxy is the Galaxy that radiates most of its total rdiation energy in the infrared region. Among infrared Galaxies, those showing particularly high luminous intensity are found, the intensity of which is equivalent to that of quasar, though the origin of such high-energy source has been uncertain. We have been engaged in the observation and data analysis of the infrared Galaxies at "Asuka", an X-ray astronomical satellite, and investigated the nature of the central nucleus. The results of the investigation revealed that most of the high luminous intensity infrared Galaxies contain active Galactic nuclei (large mass black hole), its radiation energy is not sufficiently high to explain its infrared luminous intensity, and explosive star-formation activity can be considered to occupy major part of the total radiation energy, in view of its soft X-ray intensity.
