利用虚拟天文台技术寻找适用于AGN的自适应光学
Using Virtual Observatory techniques to search for Adaptive Optics suitable AGN
摘要:
直到最近,人们才有可能详细研究中心黑洞和宿主星系之间的标度关系。由于在低红移处的数密度很小,(发光)活动星系核在这样详细的研究中代表性不足。自适应光学(AO)在大型望远镜上的出现有助于克服这一障碍,允许在很宽的红移范围内达到小的线性尺度。寻找适合AO的目标,即,AGN有一个附近的参考星,并进行初始的多波长分类是一个很好的虚拟天文台的用例。我们提出了虚拟天文台方法来选择红移0.1<z<1处发射X射线的活动星系核的AO合适目录。
英文摘要:
Until recently, it has been possible only for nearby galaxies to study the scaling relations between central black hole and host galaxy in detail. Because of the small number densities at low redshift, (luminous) AGN are underrepresented in such detailed studies. The advent of adaptive optics (AO) at large telescopes helps overcoming this hurdle, allowing to reach small linear scales over a wide range in redshift. Finding AO-suitable targets, i.e., AGN having a nearby reference star, and carrying out an initial multiwavelength classification is an excellent use case for the Virtual Observatory. We present our Virtual-Observatory approach to select an AO-suitable catalog of X-ray-emitting AGN at redshifts 0.1<z<1.
