Deep-learning Real/Bogus classification for the Tomo-e Gozen transient survey
Ichiro Takahashi, Ryo Hamasaki, Naonori Ueda +5
We present a deep neural network Real/Bogus classifier that improves classification performance in the Tomo-e Gozen transient survey by handling label errors in the training data.…
An optical search for transients lasting a few seconds
Michael W. Richmond, Masaomi Tanaka, Tomoki Morokuma +37
Using a prototype of the Tomo-e Gozen wide-field CMOS mosaic camera, we acquire wide-field optical images at a cadence of 2 Hz and search them for transient sources of duration 1.5…
"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…
Data Compression for the Tomo-e Gozen with Low-rank Matrix Approximation
Mikio Morii, Shiro Ikeda, Shigeyuki Sako +1
Optical wide-field surveys with a high cadence are expected to create a new field of astronomy, so-called "movie astronomy," in the near future. The amount of data of the observati…
ANIR : Atacama Near-Infrared Camera for the 1.0-m miniTAO Telescope
Masahiro Konishi, Kentaro Motohara, Ken Tateuchi +35
We have developed a near-infrared camera called ANIR (Atacama Near-InfraRed camera) for the University of Tokyo Atacama Observatory 1.0m telescope (miniTAO) installed at the summit…
The SPICA coronagraphic instrument (SCI) for the study of exoplanets
K. Enya, T. Kotani, K. Haze +39
We present the SPICA Coronagraphic Instrument (SCI), which has been designed for a concentrated study of extra-solar planets (exoplanets). SPICA mission provides us with a unique o…
