Mapping dusty star formation in and around a cluster at z = 0.81 by wide-field imaging with AKARI

Oyabu, Shinki; Shimasaku, Kazuhiro; Koyama, Yusei +8 more

We present environmental dependence of dusty star-forming activity in and around the cluster RXJ1716.4+6708 at z = 0.81 based on wide-field and multiwavelength observations with the Prime Focus Camera on the Subaru Telescope (Suprime-Cam) and the Infrared Camera onboard the AKARI satellite. Our optical data show that the optical colour distributio…

Timeline analysis and wavelet multiscale analysis of the AKARI All-Sky Survey at 90µm

Goto, Tomotsugu; Nakagawa, Takao; Shirahata, Mai +17 more

We present a careful analysis of the point-source detection limit of the AKARI All-Sky Survey in the WIDE-S 90-µm band near the North Ecliptic Pole (NEP). Timeline analysis is used to detect IRAS (Infrared Astronomy Satellite) sources and then a conversion factor is derived to transform the peak timeline signal to the interpolated 90-µ…
