Abstract

NEP Multi-Wavelength Data and a new band-merged catalog

Seong-Jin KIM (NTHU) and his collaborators

 The north ecliptic pole (NEP) field is a natural deep field location for many satellite observations. It has been targeted many times since it was surveyed by the AKARI space telescope with its unique wavelength coverage from the near- to mid-infrared (mid-IR). Many follow-up observations have been carried out and made this field one of the most frequently observed areas with a variety of facilities, accumulating abundant panchromatic data from X-ray to radio wavelength range. Recently, a deep optical survey with the Hyper Suprime-Cam (HSC) at the Subaru telescope covered the NEP-Wide (NEPW) field, which enabled us to identify faint sources in the near- and mid-IR bands, and to improve the photometric redshift estimation. In this work, we present newly identified AKARI sources by the HSC survey, along with multi-band photometry for 91,000 AKARI sources observed over the NEPW field. We release a new band-merged catalog combining various photometric data from GALEX UV to the submillimetre bands (e.g., Herschel/SPIRE, JCMT/SCUBA-2). This catalog motivates a variety of current research and will be increasingly useful as recently launched  and future space missions .
