The spectrum variabilities of fsrq 3c 273

WebThe Flat Spectrum Radio Quasar (FSRQ) 3C 273 is one of the most studied quasars since its discovery in 1963. It is a nearby source, with a red shift of 0.158 (Schmidt 1963). It is char-acterised by a jet close to the line-of-sight at a viewing angle of 5 − 11 (Liu & Shen 2009) and a maximum superluminal Web3C 273 is a typical flat spectrum radio quasar (FSRQ). Al-though abundance of data of 3C 273 are collected and the time structures are investigated by Soldi et al. (2008), the surprising phenomenon still brings on the new argue for physical model. Below, we will use our model to the out-burst events observed by Fermi-LAT in September 2009 in ...
