表观不协调红移类星体-星系协
Apparent discordant redshift QSO-galaxy associations
摘要：
安巴楚米安（Viktor Ambartsumian）提出了一个“奇异”的想法，即新星系是通过老星系的喷射形成的。银河系产生星系，而不是标准的情况下，星系起源于演化的种子来自波动的初始密度场。这种想法在某种程度上包含在推测性的提议中，即一些或所有的类星体可能是被附近星系抛射出来的物体，它们的红移不是宇宙学的（Arp，G./ M.伯比奇和其他人）。我将讨论一些支持和反对这种情况的论点;特别是，我将谈论在明显不和谐的类星体星系红移协会中存在的真实物理联系。一方面，高红移类星体和邻近星系之间有许多统计上的相关性，这些相关性还不能用引力透镜、偏置或选择效应来解释;而且某些特殊的配置是背景天体投影的概率非常低。我们对类星体的总体理解也远未完成。另一方面，一些过去被认为不正常的案例，却找到了标准术语的解释。作为一个例子，我将展示我们自己对这种类型的研究的一些案例：邻近星系周围ULX的统计数据，以及Flesch & Hardcastle候选类星体目录分析。我的结论是中立的。
英文摘要：
An "exotic" idea proposed by Viktor Ambartsumian was that new galaxies are formed through the ejection from older active galaxies. Galaxies beget galaxies, instead of the standard scenario in which galaxies stem from the evolution of the seeds derived from fluctuations in the initial density field. This idea is in some way contained in the speculative proposal that some or all QSOs might be objects ejected by nearby galaxies, and that their redshift is not cosmological (Arp, G./M. Burbidge and others). I will discuss some of the arguments for and against this scenario; in particular, I shall talk about the existence of real physical connections in apparently discordant QSO-galaxy redshift associations. On the one hand, there are many statistical correlations of high-redshift QSOs and nearby galaxies that cannot yet be explained in terms of gravitational lensing, biases, or selection effects; and some particular configurations have very low probabilities of being a projection of background objects. Our understanding of QSOs in general is also far from complete. On the other hand, some cases which were claimed to be anomalous in the past have found an explanation in standard terms. As an example, I will show some cases of our own research into this type: statistics of ULXs around nearby galaxies, and the Flesch & Hardcastle candidate QSOs catalog analysis. My own conclusion is neutral.
