Andromeda Galaxy Image Processed By The HSC Data Analysis Software
Kavli Institute for the Physics and Mathematics of the Universe
Today, researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) released the first image of the Andromeda Galaxy (M31) processed with the data analysis software developed for the Subaru Telescope's Hyper Suprime-Cam (HSC). The HSC project's 'first light' was announced last week (A New View on the Origin of Dark Matter and Dark Energy - Image of M31 Heralds the Dawn of HSC). Researchers at the Kavli IPMU have collaborated with Princeton University and the National Astronomical Observatory of Japan (NAOJ) to develop the HSC data analysis pipeline. The sharp images of stars over such a wide field of view demonstrates the HSC's outstanding power. Such image quality will be indispensable for researchers hoping to reveal the nature of dark matter and dark energy in the universe.
Naoki Yasuda, Professor at the Kavli IPMU, who plays a key role on the HSC data processing, said, "There is no doubt that HSC is the finest wide field, high resolution camera in the world. In order to accelerate scientific research, however, the data taken by HSC have to be handled adequately and the maximum amount of information contained in the data has to be extracted as soon as possible. To realize this requirement, we have been developing the HSC data analysis pipeline. Today we have confirmed the performance of our pipeline software using data from HSC's first light observations. We're very pleased with the results, but we will continue to tune-up the software more before the survey observations are underway, and while the survey progresses."
Funding for the HSC Project was provided in part by the following grants: Grant-in-Aid for Scientific Research (ID 15340065) to S. Miyazaki (NAOJ); Grant-in-Aid for Scientific Research on Priority Areas (ID 18072003) to H. Karoji (first at NAOJ, then at Kavli IPMU); and the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST) entitled, "Uncovering the Origin and Future of the Universe-ultra-wide-field imaging and spectroscopy reveal the nature of dark matter and dark energy" to H. Murayama (Kavli IPMU).
