摘要:

用229618个窄发射线星系的样本建立了两种新的关于核中心存在超大质量黑洞的明确证据:1)Seyfert 2星系和LINER星系的电离流光度与连续光谱光度之间遵循相同的特征幂律关系; 2)两者都在其中心显示出最高的质量浓度,与星系的形态无关,与较高的结合能一致。半峰宽与质量浓度有关,说明活动星系核中气体的动能具有引力来源。在标准的吸积模型中,过渡型天体、Seyfert 2星系和LINER代表活动星系核形成不同质量尺度的超大质量黑洞,或者它们可以通过一个演化过程联系起来,LINER代表这一演化的最终产物。

英文摘要:

A sample of 229618 narrow emission-line galaxies is used to establish two new unambiguous type of evidence for supermassive black holes at the center of their nuclei: 1) the Seyfert 2 galaxies and LINERs follow the same characteristic power law relating the luminosity of ionized flux with that of the continuum; 2) both show the highest concentration of mass at their center, independent of the morphology of the galaxy, consistent with higher binding energies. The Full Width at Half Maximum is shown to be related with the mass concentration, suggesting that the kinetic energy of the gas in AGNs has a gravitational origin. Within the standard accretion model, the Transition-type Objects, Seyfert 2 galaxies and LINERs represent AGNs forming supermassive black holes on different mass-scales, or they could be related through an evolutionary process, the LINERs representing the end product of this evolution.
