Demonstration of Plate Analysis, an algorithm for precise relative astrometry
Ryou Ohsawa, Daisuke Kawata, Takafumi Kamizuka +3
Astrometry plays a crucial role in understanding the structure, dynamics, and evolution of celestial objects by providing precise measurements of their positions and motions. We pr…
JASMINE image simulator for high-precision astrometry and photometry
Takafumi Kamizuka, Hajime Kawahara, Ryou Ohsawa +23
JASMINE is a Japanese planned space mission that aims to reveal the formation history of our Galaxy and discover habitable exoEarths. For these objectives, the JASMINE satellite pe…

"Slow-Scanning" in Ground-Based Mid-Infrared Observation
Ryou Ohsawa, Shigeyuki Sako, Takashi Miyata +8
Chopping observations with a tip-tilt secondary mirror have conventionally been used in ground-based mid-infrared observations. However, it is not practical for next generation lar…
