包含伽马射线暴的黑洞活动的普适标度律

A universal scaling law of black hole activity including gamma-ray bursts

F. Y. Wang, Z. G. Dai

摘要:

以往的工作表明,射电光度、X射线光度和黑洞质量之间存在着从X射线双星中的恒星质量黑洞到活动星系核(AGN)中的超大质量黑洞的相关性,这导致了黑洞活动的基本面。然而,对于这个基本平面有两种相互竞争的解释,包括喷流主导模型和圆盘喷流模型。因此,这个基本平面的物理起源仍然未知。本文指出,伽马射线暴(GRB)和M82 X-1的X射线光度、射电光度和BH质量也呈现相似的分布。恒星质量、中等质量和超大质量BH系统之间的普遍标度律,以及伽玛暴的射电和X射线发射起源于相对论喷流的事实,揭示了BH活动的基本平面受喷流控制,即,射电和X射线辐射主要来自喷流。我们的工作还表明,喷流是标度不变的BH质量。

英文摘要:

Previous works show that a correlation among radio luminosity, X-ray luminosity, and black hole (BH) mass from stellar-mass BHs in X-ray binaries to supermassive BHs in active galactic nuclei (AGNs), which leads to the so-called fundamental plane of BH activity. However, there are two competing explanations for this fundamental plane, including the jet-dominated model and the disk-jet model. Thus, the physical origin of this fundamental plane remains unknown. In this paper, we show that the X-ray luminosities, radio luminosities and BH masses of gamma-ray bursts (GRBs) and M82 X-1 also show a similar distribution. The universal scaling law among stellar-mass, intermediate and supermassive BH systems, together with the fact that radio and X-ray emission of GRBs originates from relativistic jets, reveals that the fundamental plane of BH activity is controlled by a jet, i.e., the radio and X-ray emission is mainly from the jet. Our work also suggests that the jets are scale-invariant with respect to the BH mass.
