星系形成的理论模型表明,一个活动星系核(AGN)的存在需要通过反馈机制来调节其宿主星系的生长,例如AGN驱动的外流。虽然这种外流在低红移和高红移都很常见,但仍然缺少一个全面的图像。到目前为止,对星系集合的峰值时期(1<z<3)的探索还很有限,目前在这个红移范围内的观测大多局限于很有可能处于流出阶段的目标。本文介绍了欧洲南方天文台正在进行的VLT/SINFONI大型计划SUPER(a SINFONI Survey for Unveiling the Physics and Effect of Radiative Feedback)。SUPER将在z~2处对39个X射线AGN的相当大的盲选样本进行电离流出的首次系统研究,由于自适应光学辅助IFU观察,该样本达到了高空间分辨率(~2 kpc)。通过[OIII]的宽分量和Ha发射线的窄分量,将绘制出宿主星系中的外流形态和恒星形成。我们的调查的主要目的是推断流出对正在进行的恒星形成的影响,并将流出属性与一些活动星系核和宿主星系的属性联系起来。我们在这里描述调查的特点和目标,以及目标样本的选择。此外,我们提出了其多波长特性的完整表征:我们通过紫外-远红外测光的光谱能量分布拟合来测量恒星质量(4x10^9-2x10^11 Msun),恒星形成率(25-680 Msun yr^-1)和活动星系核的辐射热光度(2x10^44-8x10^47 erg s^-1),以及通过X射线光谱分析得到的暗柱密度(<2x10^24 cm^-2)和2-10 keV的光度(2x10^43-6x10^45 erg s^-1)。最后,我们根据射电和远红外辐射将活动星系核分为喷流和非喷流两类。
英文摘要:
Theoretical models of galaxy formation suggest that the presence of an active galactic nucleus (AGN) is required to regulate the growth of its host galaxy through feedback mechanisms, produced by e.g. AGN-driven outflows. Although such outflows are common both at low and high redshift, a comprehensive picture is still missing. The peak epoch of galaxy assembly (1<z<3) has been poorly explored so far, and current observations in this redshift range are mostly limited to targets with high chances to be in an outflowing phase. This paper introduces SUPER (a SINFONI Survey for Unveiling the Physics and Effect of Radiative feedback), an ongoing ESO's VLT/SINFONI Large Programme. SUPER will perform the first systematic investigation of ionized outflows in a sizeable and blindly-selected sample of 39 X-ray AGN at z~2, which reaches high spatial resolutions (~2 kpc) thanks to the adaptive optics-assisted IFU observations. The outflow morphology and star formation in the host galaxy will be mapped through the broad component of [OIII] and the narrow component of Ha emission lines. The main aim of our survey is to infer the impact of outflows on the on-going star formation and to link the outflow properties to a number of AGN and host galaxy properties. We describe here the survey characteristics and goals, as well as the selection of the target sample. Moreover, we present a full characterization of its multi-wavelength properties: we measure, via spectral energy distribution fitting of UV-to-FIR photometry, stellar masses (4x10^9-2x10^11 Msun), star formation rates (25-680 Msun yr^-1) and AGN bolometric luminosities (2x10^44-8x10^47 erg s^-1), along with obscuring column densities (<2x10^24 cm^-2) and 2-10 keV luminosities (2x10^43-6x10^45 erg s^-1) derived through X-ray spectral analysis. Finally, we classify our AGN as jetted or non-jetted according to their radio and FIR emission.

Ionized outflows in luminous type 2 AGNs at z<0.6: no evidence for significant impact on the host galaxies
我们研究了18个发光的2型活动星系核(11个类星体和7个高光度Seyfert 2s)中在0.3<z <0.6 based on VLT-FORS2 spectroscopy. We infer typical lower limits on the radial sizes of the outflows R>=几× 100秒差距和上限R<1-2 kpc的扩展电离外流的存在。我们的结果与相关的研究不一致,这些研究表明,大尺度R~几-15 kpc是普遍存在的类星体。我们研究了可能的原因的差异,并提出,看到涂抹是大推断尺寸的原因。我们对反馈现象的理解是重要的,因为流出的质量M(通过密度),质量注入M(点)和能量注入率E(点)变得高度不确定。一个结论似乎是不可避免的:M,M(点),E(点)与以前的估计相比是适度或较低的。没有证据表明典型的外流可以影响宿主星系的星际介质,其空间尺度大于1-2 kpc。
Ionized outflows in local luminous AGN: what are the real densities and outflow rates?
我们报告的电子密度的测定,以及它们对流出的质量和速率的影响,在中央几百秒差距的11个本地发光的活动星系测量。我们发现,在活动星系核的积分线发射的峰值是显着偏移的系统速度跟踪的恒星吸收功能,这表明该配置文件是由外流为主。相比之下,匹配的不活跃星系的特点是系统的峰值和较弱的外流翼。我们提出了三个独立的估计,在这些活动星系核的电子密度,讨论了不同方法的优点。来自[SII]双峰的电子密度显着低于发现在过去十年中开发的方法使用极光和transauroral线,以及最近推出的方法的电离参数的基础上。原因是,对于由活动星系核光电离的气体,大部分的[SII]发射出现在一个扩展的部分电离区,其中隐含的假设,即电子密度跟踪氢密度是无效的。我们提出了处理这种情况的方法,并推导出电离气体的相关流出率,对于我们的活动星系核样品,流出率在0.001- 0.5 M $_{\odot}$/年$^{-1}$范围内。我们将这些流出率与文献中$\dot{M}_{out}$和$L_{AGN}$之间的关系进行比较,并认为可能需要对它进行修改并重新调整以降低质量流出率。

Discovery of a strong ionized-gas outflow in an AKARI-selected Ultra-luminous Infrared Galaxy at z = 0.5
为了构造一个0.5 < z < 1的超亮红外星系(ULIRGs,具有红外光度,$L_{\rm IR} > 10^{12}$ L $_{\odot}$)的样本,我们正在进行一个光学跟踪计划,以获得明亮的90- $μ$ m远红外源,并在AKARI远红外巡天(FIS)亮源目录(Ver.2)中选择一个暗淡的光学(i < 20)对应源。AKARI-FIS-V2 J 0916248 +073034在光谱跟踪观测中被识别为z = 0.49的ULIRG,表明其发射线轮廓中存在极强外流的特征。它的[OIII] 5007发射线相对于恒星吸收线的半高宽为1830 km s $^{-1}$,速度漂移为-770 km s $^{-1}$。此外,低电离态[OII] 3726 3729双谱线还显示出910 km s $^{-1}$的大半高宽和-380 km s $^{-1}$的速度漂移。在去除未分辨的核成分后,长缝光谱2D图像可能显示流出物延伸到4kpc的半径。质量外流和能量喷射率分别为500 M $_{\odot}$ yr $^{-1}$和$4\times10^{44}$ erg s $^{-1}$,这意味着在0.3 < z < 1.6时,外流是ULIRGs和类星体中观测到的最强的外流。强外流和强烈的恒星形成(恒星形成速率为990 M $_{\odot}$ yr $^{-1}$)的共存表明,强外流的反馈对星系…
