AKARI-HSC Band-Merged Catalog in the North Ecliptic Pole Wide Field (NEPW)

The North Ecliptic Pole 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, making this field one of the most frequently observed areas with a variety of facilities, accumulating abundant panchromatic data from the X-ray to the 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 Kim et al. (2021) to identify faint sources in the near- and mid-IR bands, and to improve the photometric redshift (photo-z) estimation. The AKARI-HSC Band-Merged Catalog in the NEPW Field contains multiband photometry for 91,861 AKARI sources observed over the NEPW field. It combines various photometric data from the GALEX UV to submillimetre (sub-mm) bands (e.g. Herschel/SPIRE, JCMT/SCUBA-2). About 20,000 AKARI sources are newly matched to the HSC data, most of which seem to be faint galaxies in the near- to mid-infrared AKARI bands.
