The optical spectra of 3,896 Seyfert~1 (Sy1) galaxies detected with WISE at z < 0.4 were analyzed for evidence of outflows. In 37% of the Sy1s the outflows appear as broad, blue-shifted, of the [OIII]5007, with a mean maximum velocity V_max ~1014 km/s$, consistent with AGN winds. For each Sy1 we deduced that black hole (BH) mass, bolometric luminosity, Eddington ratio and power-law index of the continuum, which we compared with the star formation rate (SFR) and host morphology. Having separated our sample in two spectroscopic subgroups, Sy1s with only broad Balmer lines (Sy1B) and with both narrow and broad (Sy1N) lines and distinguishing those that show as outflow (Sy1Bw and Sy1Nw), we report the following differences: 1) the BH mass is systematically higher and the power-law steeper in the Sy1B-Sy1Bw than in the Sy1N-Sy1Nw, 2) V_max is higher in the Sy1Bw than in the Sy1Nw, correlated in both groups with the BH mass and bolometric luminosity, 3) the Eddington ratio and SFR are higher in the Sy1 with outflows, and 4) the specific star formation rates (sSFRs) of the Sy1s are normal for their morphology and mass; typical of early-type spiral galaxies in the green valley, far from the quenched regime. From these results we conclude that in Sy1s AGN winds are triggered by higher accretion rates and probably radiatively launched, and there is no clear evidence of an effect on the star formation.

在低红移的赛弗特 1 星系中普遍存在 AGN 风

分析了用 WISE 在 z < 0.4 处探测到的 3,896 个 Seyfert~1 (Sy1) 星系的光谱以寻找外流的证据。在 37% 的 Sy1s 中,外流表现为 [OIII]5007 的广泛蓝移,平均最大速度 V_max ~1014 km/s$,与 AGN 风一致。对于每个 Sy1,我们推导出了黑洞 (BH) 质量、热光度、爱丁顿比和连续体的幂律指数,我们将其与恒星形成率 (SFR) 和宿主形态进行了比较。将我们的样本分为两个光谱亚组,Sy1s 只有宽巴尔默线 (Sy1B) 和窄和宽 (Sy1N) 线,并区分那些显示为流出的 (Sy1Bw 和 Sy1Nw),我们报告了以下差异:1)与 Sy1N-Sy1Nw 相比,Sy1B-Sy1Bw 中的 BH 质量系统地更高且幂律更陡峭,2)Sy1Bw 中的 V_max 高于 Sy1Nw,这在两组中都与 BH 质量和热光度相关,3)Sy1 中的爱丁顿比和 SFR 在流出时更高,以及 4)特定的恒星形成率(sSFR) ) Sy1s 的形态和质量是正常的;绿色山谷中典型的早型螺旋星系,远离淬火状态。从这些结果我们得出结论,在 Sy1s 中,AGN 风是由较高的吸积率触发的,并且可能是辐射发射的,并且没有明确的证据表明对恒星形成有影响。绿色山谷中典型的早型螺旋星系,远离淬火状态。从这些结果我们得出结论,在 Sy1s 中,AGN 风是由较高的吸积率触发的,并且可能是辐射发射的,并且没有明确的证据表明对恒星形成有影响。绿色山谷中典型的早型螺旋星系,远离淬火状态。从这些结果我们得出结论,在 Sy1s 中,AGN 风是由较高的吸积率触发的,并且可能是辐射发射的,并且没有明确的证据表明对恒星形成有影响。
