Research Abstract

The award of the kakenhi has helped me to make important new research on black holes, galaxies and stars. Based upon my work, accurate measurements of the infrared light can now be used to study the intrinsic black hole properties easily. I have also obtained the most accurate images of dust from dying stars in the nearest galaxy where active star-formation is occurring. I have been able to carry out several new studies using Japan's Subaru, Akari and Suzaku telescopes, in combination with other new telescopes around the world. My work has also been publicized in press releases.
