2dF红移巡天II：UGC 8584-红移周期和环
The 2dF Redshift Survey II: UGC 8584 - Redshift Periodicity and Rings
摘要：
UGC 8584被一个计算机程序选中，因为它周围有许多类星体，这些类星体在其参考系中遵循卡尔松周期。经过更仔细的检查，最近的10个类星体中有9个非常接近预测值。此外，UGC 8584是一个扰动的三重星系和一个强的三重射电源，也是一个强的毫米波和红外源。证据表明，目前的喷射速度$z_v \sim .01$的相关类星体是存在的，并指出一些配对的喷射。从这个星系/类星体家族的样本中出现了一个新的和重要的结果，即星系和类星体的环和壳层倾向于包围具有活跃核的星系。测试案例表明，这些星系周围的背景模糊了约20 '或更远。由于没有观察到强红化的事件，因此与光学波长相比，模糊粒子被认为是大的。原则上，与类星体一起喷出的物质可能是砾石大小或更大。
英文摘要：
UGC 8584 was selected by a computer program as having a number of quasars around it that obeyed the Karlsson periodicity in its reference frame. On closer examination 9 of the nearest 10 quasars turned out to be extremely close to the predicted values. Also it turned out that UGC 8584 was a disturbed triple galaxy and a strong triple radio source as well as being a strong millimeter and infrared source. Evidence for present ejection velocities of $z_v \sim .01$ for the associated quasars is present and some pairing of ejections is noted. A new and important result emerges from this sample of galaxy/quasar families, namely that rings and shells of galaxies and quasars tend to surround galaxies which have active nuclei. Test cases suggest obscuration of the background around these galaxies out to about 20' or beyond. Because incidents of strong reddening are not observed, obscuring particles are suggested to be large compared to optical wavelengths. In principle, material ejected with the quasars could be of sizes of gravel or larger.
