- W3148616090 abstract "Microvariability across the whole electromagnetic spectrum in blazars was first discovered in 1960s.It began to get extensive attention in 1980s.After twenty years' investigation, the physical mechanism leading to microvariability has not been found.Several models exist in explaining this phenomenon in the literature.The most widely accepted one is the shockin -jet model.In this model,shocks propagating along the relativistic jet and interacting with the hydrodynamically turbulent plasma and twisted magnetic field should be responsible for the microvariability. Spectral variability is always found when a blazar shows variability in brightness in both short and long timescale.There are many different phenomena.Some blazars,generally flat spectrum radio quasars,become redder when brighter.Some(generally BL Lac objects) show the opposite trend-bluer when brighter.Some show no spectral variability at all.When blazars are in different states,they exhibit different behavior in spectral variability.As an example,in the outburst of OJ 287 in 1994,it showed no color change at all.However,in its 2005 outburst,it was observed to be bluer when brighter.Another example is S5 0716+714,it has been observed to be bluer when brighter,redder when brighter as well as show no spectral change with brightness. This paper provides a comprehensive review of the historical study of microvariability as well as spectral variability of seven most extensively observed blazars,namely 3C 279,3C 454.3,3C 66A,AO 0235+164,BL Lac,OJ 287,S5 0716+714.Models for these blazars' variability are also simply introduced." @default.
