We performed the search for active galactic nuclei (AGNs) using AKARI mid-infrared (MIR) all-sky survey. “AKARI” is the first Japanese infrared satellite dedicated for infrared astronomy. Especially, our MIR searchcan find not only normal AGNs but also dusty AGNs which are elusive in other wavelengths. Combining AKARI data with optical spectra taken with ground-based telescopes and X-ray data of the Japanese X-ray satellite “Suzaku”, we found three dusty AGNs which do not show any AGN features in other wavelength but infrared band.We also found that the host galaxies of these dusty AGNs are less massive than AGNs that are found with optical spectroscopic surveys. While this result comes from small statistics, our survey will provide the expectation of future search for dusty AGNs.

我们使用AKARI中红外（MIR）全天巡天进行了活动星系核（AGN）的搜索。“AKARI”是日本第一颗专门用于红外天文学的红外卫星。特别是，我们的MIR搜索不仅可以发现正常的活动星系核，而且还可以发现在其他波段难以发现的尘埃活动星系核。结合AKARI观测数据、地面望远镜观测的光谱和日本X射线卫星“朱雀”的X射线观测数据，我们发现了3个尘埃活动星系核，它们在红外波段以外的波段没有活动星系核的特征，而且它们的宿主星系质量比光谱观测发现的活动星系核小。虽然这一结果来自小的统计，我们的调查将提供未来的搜索尘埃活动星系核的期望。
