摘要:

为揭示辐射反馈的物理学和效应而进行的SINFONI巡天旨在追踪和描述电离气体外流及其对z $\sim$ 2的X射线选定活动星系核(AGN)统计样本中恒星形成的影响。我们提出的第一个SINFONI结果的21个1型活动星系核的样本跨越广泛的热光度范围(log $\mathrm{L_{bol}}$ = 45.4-47.9 erg/s)。本文的主要目的是确定电离气体的延伸,描述活动星系核驱动外流的发生,并将这种外流的性质与活动星系核的性质联系起来。我们使用自适应光学辅助SINFONI观测跟踪电离气体在扩展的窄线区域使用[OIII]5007线。我们分类为托管流出的目标,如果它的非参数速度的[OIII]线,$\mathrm{w_{80}}$,是大于600公里/秒。我们研究了扩展发射的存在下,使用专用的点扩散函数(PSF)的观测,建模后的PSF从巴耳末线起源于宽线区域。根据积分谱的$\mathrm{w_{80}}$值,在650-2700 km/s范围内,我们在所有的第一型活动星系核样品中都探测到了外流。$\mathrm{w_{80}}$与活动星系核的热光度有明显的正相关关系(相关概率为99%),但与黑洞质量的相关性较弱(相关概率为80%)。PSF和[OIII]径向分布的比较表明,[OIII]发射在$\sim$ 35%的1型样品中是空间分辨的,流出物显示出高达$\sim$ 6 kpc的延伸。最大速度和热光度之间的关系是一致的模型预测的冲击活动星系核驱动流出。外流气体的逃逸率随活动星系核光度的增加而增加,但对大多数星系来说,这一比例小于10%。

英文摘要:

The SINFONI survey for Unveiling the Physics and Effect of Radiative feedback (SUPER) aims at tracing and characterizing ionized gas outflows and their impact on star formation in a statistical sample of X-ray selected Active Galactic Nuclei (AGN) at z$\sim$2. We present the first SINFONI results for a sample of 21 Type-1 AGN spanning a wide range in bolometric luminosity (log $\mathrm{L_{bol}}$ = 45.4-47.9 erg/s). The main aims of this paper are determining the extension of the ionized gas, characterizing the occurrence of AGN-driven outflows, and linking the properties of such outflows with those of the AGN. We use Adaptive Optics-assisted SINFONI observations to trace ionized gas in the extended narrow line region using the [OIII]5007 line. We classify a target as hosting an outflow if its non-parametric velocity of the [OIII] line, $\mathrm{w_{80}}$, is larger than 600 km/s. We study the presence of extended emission using dedicated point-spread function (PSF) observations, after modelling the PSF from the Balmer lines originating from the Broad Line Region. We detect outflows in all the Type-1 AGN sample based on the $\mathrm{w_{80}}$ value from the integrated spectrum, which is in the range 650-2700 km/s. There is a clear positive correlation between $\mathrm{w_{80}}$ and the AGN bolometric luminosity (99% correlation probability), but a weaker correlation with the black hole mass (80% correlation probability). A comparison of the PSF and the [OIII] radial profile shows that the [OIII] emission is spatially resolved for $\sim$35% of the Type-1 sample and the outflows show an extension up to $\sim$6 kpc. The relation between maximum velocity and the bolometric luminosity is consistent with model predictions for shocks from an AGN driven outflow. The escape fraction of the outflowing gas increase with the AGN luminosity, although for most galaxies, this fraction is less than 10%.
