Search for hidden Active Galactic Nuclei using Infrared satellite "AKARI" mid-infrared survey

我们使用AKARI中红外（MIR）全天巡天对活动星系核（agn）进行了搜索。“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agn，还可以发现在其他波长难以捉摸的尘埃agn。结合AKARI数据、地基望远镜的光谱和日本“Suzaku”x射线卫星的x射线数据，我们发现了三个尘埃AGN，它们在红外波段外没有任何AGN特征。我们还发现，这些尘埃agn的宿主星系比通过光学光谱调查发现的agn质量要小。虽然这个结果来自小的统计数据，但我们的调查将为未来寻找多尘agn提供预期。

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.
