论文摘要
关于红色和蓝色准恒星对象(QSO)的最新工作已将特殊的数字分布确定为无线电响度的函数,我们探索并试图从图片的角度来解释,在该图片的角度来看,活动星系人口的子集从无线电响亮的无线电响亮的无线电响亮的无线电响亮。由于无线电安静阶段的时间演变被一个数量级或更多的数量级减慢,因此红色和蓝色QSO的数量在无线电安静的无线电范围的极端彼此接近,无线电响度的数量更大。相反,大多数无线电大声阶段的快速演变使数字相似,但在遥远的无线电大声端处于较低的速度。相反,在无线电响度的中点,红色和蓝色QSO之间的差异经历了它们最大的值,这是由于积聚而迅速旋转黑洞,但随后将它们旋转得更慢。恢复观察结果的这些基本特征是从无线电响度和无线电安静状态下缓慢演变的迅速发展的证据。
Recent work on red and blue quasi-stellar objects (QSOs) has identified peculiar number distributions as a function of radio loudness that we explore and attempt to explain from the perspective of a picture in which a subset of the population of active galaxies evolves from the radio loud to the radio quiet state. Because the time evolution is slowed down by an order of magnitude or more for the radio quiet phase, the numbers of red and blue QSOs approach each other at the extreme end of the radio quiet range of radio loudness with larger numbers. The rapid time evolution of most radio loud phases, instead, makes the numbers similar but lower at the far radio loud end. At the midpoint of radio loudness, instead, the differences between red and blue QSOs experience their largest values which results from accretion rapidly spinning black holes down but subsequently spinning them up more slowly. Recovering these basic features of the observations is evidence for rapid evolution away from radio loudness and slow evolution in radio quiet states.
