Abstract

We present an optical imaging survey of AKARI Deep Field South (ADF-S) using the Korea Microlensing Telescope Network (KMTNet), to find optical counterparts of dusty star-forming galaxies. The ADF-S is a deep far-infrared imaging survey region with AKARI covering around 12 deg², where the deep optical imaging data are not yet available. By utilizing the wide-field capability of the KMTNet telescopes (~4 deg²), we obtain optical images in B, R and I bands for three regions. The target depth of images in B, R and I bands is ~24 mag (AB) at 5σ, which enables us to detect most dusty star-forming galaxies discovered by AKARI in the ADF-S. Those optical datasets will be helpful to constrain optical spectral energy distributions as well as to identify rare types of dusty star-forming galaxies such as dust-obscured galaxy, sub-millimeter galaxy at high redshift.

用kmtnet对akari深场南部尘埃恒星形成星系的光学调查

我们使用韩国微透镜望远镜网络(KMTNet)对AKARI深场南部(ADF-S)进行了光学成像调查，以寻找尘埃恒星形成星系的光学对偶。ADF-S是一个深远红外成像调查区域，AKARI覆盖约12°²，其中深光学成像数据尚未获得。利用KMTNet望远镜(~4°²)的宽视场能力，我们获得了三个区域的B、R和I波段的光学图像。B, R和I波段图像的目标深度为~24等(AB)，在5σ，这使我们能够探测到AKARI在ADF-S中发现的大多数尘埃恒星形成星系。这些光学数据集将有助于限制光谱能量分布，以及识别罕见类型的尘埃恒星形成星系，如尘埃遮挡星系，高红移亚毫米星系。
