JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
Detectability of optical transients with timescales of sub-seconds
Ko Arimatsu, Kohji Tsumura, Fumihiko Usui +2
We search for optical transient sources with durations of to s using a dataset obtained in the Organized Autotelescopes for Serendipitous Event Survey (OASES)…
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…
Organized Autotelescopes for Serendipitous Event Survey (OASES): design and performance
Ko Arimatsu, Kohji Tsumura, Kohei Ichikawa +7
Organized Autotelescopes for Serendipitous Event Survey (OASES) is an optical observation project that aims to detect and investigate stellar occultation events by kilometer-sized…
Calibration of the AKARI Far-infrared All Sky Survey Maps
Satoshi Takita, Yasuo Doi, Takafumi Ootsubo +10
We present an initial analysis of the properties of the all-sky image obtained by the Far-Infrared Surveyor (FIS) onboard the AKARI satellite, at 65~m (N60), 90~m (WIDE-S), 1…
Point source calibration of the AKARI/FIS all-sky survey maps for staking analysis
Ko Arimatsu, Yasuo Doi, Takehiko Wada +5
Investigations of the point spread functions (PSFs) and flux calibrations for stacking analysis have been performed with the far-infrared (wavelengths range of 60 to 140 um all-sky…
Characterization and Improvement of the Image Quality of the Data Taken with the Infrared Camera (IRC) Mid-Infrared Channels onboard AKARI
Ko Arimatsu, Takashi Onaka, Itsuki Sakon +7
Mid-infrared images frequently suffer artifacts and extended point spread functions (PSFs). We investigate the characteristics of the artifacts and the PSFs in images obtained with…
