标题： Identification of AKARI infrared sources by Deep HSC Optical Survey: Construction of New Band-Merged Catalogue in the NEP-Wide field

摘要： 北黄道极（NEP）区域是许多卫星观测的自然深空场。自AKARI空间望远镜以其从近红外到中红外（mid-IR）的独特波长覆盖进行了调查以来，该区域已被多次针对。已进行了许多后续观测，使该区域成为使用多种设施频繁观测的区域之一，积累了从X射线到射电波长范围的丰富多波段数据。最近，使用昴星团望远镜上的Hyper Suprime-Cam进行的深度光学调查覆盖了NEP-Wide（NEPW）区域，使我们能够识别近红外和中红外波段的微弱源，并改进光度红移（photo-z）估计。在这项工作中，我们展示了通过HSC调查新识别的AKARI源，并提供了对NEPW区域中91,861个AKARI源的多波段光度测量。我们发布了一个新的波段合并目录，结合了从GALEX紫外到亚毫米（sub-mm）波段（例如，Herschel/SPIRE，JCMT/SCUBA-2）的各种光度数据。大约20,000个AKARI源新匹配到了HSC数据，其中大部分似乎是在近红外和中红外AKARI波段中的微弱星系。该目录将激发各种当前的研究，并且随着最近发射的（eROSITA/ART-XC）和未来的空间任务（如JWST、Euclid和SPHEREx）计划在NEP区域进行深度观测，其用途将越来越广泛。 显示英文摘要

摘要： The north ecliptic pole (NEP) field is a natural deep field location for many satellite observations. It has been targeted manytimes 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 witha variety of facilities, accumulating abundant panchromatic data from X-ray to radio wavelength range. Recently, a deep opticalsurvey with the Hyper Suprime-Cam (HSC) at the Subaru telescope covered the NEP-Wide (NEPW) field, which enabled us toidentify faint sources in the near- and mid-IR bands, and to improve the photometric redshift (photo-z) estimation. In this work,we present newly identified AKARI sources by the HSC survey, along with multi-band photometry for 91,861 AKARI sourcesobserved over the NEPW field. We release a new band-merged catalogue combining various photometric data from GALEXUV to the submillimetre (sub-mm) bands (e.g., Herschel/SPIRE, JCMT/SCUBA-2). About 20,000 AKARI sources are newlymatched to the HSC data, most of which seem to be faint galaxies in the near- to mid-infrared AKARI bands. This cataloguemotivates a variety of current research, and will be increasingly useful as recently launched (eROSITA/ART-XC) and futurespace missions (such as JWST, Euclid, and SPHEREx) plan to take deep observations in the NEP field.
