摘要
A random superposition of elementary luminosity bursts of rectangular or triangular shape produces X-ray luminosity flicker curves characterized by features corresponding to those observed in the X-ray-variable Seyfert galaxies and other active galactic nuclei. Such luminosity events could be produced by accretion processes resulting from tidal disruption and consumption of stars by small (approximately 1 M.) black holes, or much more frequently from such holes passing and disrupting accretion disks belonging to large holes in a nuclear cluster.
