The University of Tokyo), Bunkyo-ku, Tokyo, Japan, In this research, we provide a new, efficient method to select infrared (IR) active galactic nucleus (AGN). In the past, AGN selection in IR had been established by many studies using color-color diagrams, because the number of filters of IR telescopes is limited. The AKARI North Ecliptic Pole (NEP) survey was carried out by the AKARI Infrared Camera (IRC), which has 9 filters in mid-IR with a continuous wavelength coverage from 2 to 24 micrometers. Taking advantage of the intrinsically different mid-IR features of AGN and star-forming galaxies (SFGs), we performed SED fitting to separate these two populations by the best-fitting model. In the X-ray AGN sample, our method by SED fitting selects 50% AGNs, while the previous method by colour criteria recovers only 30% of them, which is a significant improvement. Furthermore, in the whole NEP deep sample, SED fitting selects two times more AGNs than the color selection. This may imply that the black hole accretion history could be more stronger than previous estimates., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730026071, レポート番号: JAXA-SP-17-009E},
