类星体与微类星体:尺度关系与粒子加速

Quasars vs. Microquasars: Scaling and Particle Acceleration

J. I. Katz

AI总结:

本研究比较类星体与微类星体的粒子加速效率,指出前者射电光度占热光度比例远高于后者,并归因于吸积盘参数随黑洞质量的尺度变化。

摘要:

类星体和微类星体都包含吸积黑洞,并为非热射电源提供动力,但二者的差异不仅在于尺度:类星体按比例而言是高能电子高效得多的加速器。与类星体相关的双射电源的射电光度反映了粒子加速功率的长期平均值,通常占类星体热光度的1%至30%;而在微类星体中,这一比例为≲10⁻⁵。这或许可以用吸积盘参数随黑洞质量的尺度变化来解释。

英文摘要:

Quasars and microquasars both contain accreting black holes and power nonthermal radio sources but differ in more than their scales: Quasars are proportionally much more efficient accelerators of energetic electrons. The radio luminosity of the double radio sources associated with quasars, reflecting the long-time average of the particle acceleration power, is often 1-30% of the quasar's bolometric luminosity; in microquasars the fraction is $\lesssim 10^{-5}$. This may be explained by the scaling of accretion disc parameters with the black hole mass.
