Quasars and microquasars both contain accreting black holes and power nonthermal double 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 ≲10⁻⁵. This may be explained by the scaling of accretion disk parameters with the black hole mass.

类星体与微类星体：尺度和粒子加速

类星体和微类星体都包含吸积黑洞和非热双射电源，但它们的不同之处不仅仅在于它们的规模：类星体是高能电子加速器，比例上要高效得多。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，通常为类星体测辐射热光度的1%~30%；在微类星体中，该分数为 ≲10 ^-5。这可以通过吸积盘参数与黑洞质量的缩放来解释。
