附近明亮的类星体3C273有一个扩展的多波段喷流，其强度的空间模式在不同的波段之间有很大的不同。我们认为，通常的同步加速器模型只考虑了喷流的射电功率。相反，我们看到的所有高能光子都是来自明亮类星体核心的次要、误导的光子，这些光子被喷流中的物质散射到了我们的路径上。该模型很好地描述了喷流在所有较高频段的形状、光谱、偏振和强度分布。尘埃似乎不能散射所见的X射线，但汤姆森散射适用于所有波段。
The nearby bright quasar 3C273 has an extended multiband jet whose spatial pattern of intensity differs strongly from band to band. We propose that only the radio power of the jet is accounted for by the usual synchrotron model. All the higher energy photons seen are instead secondary, misdirected photons from the bright quasar core scattered our way by material within the jet. This model gives a good account of form, spectrum, polarization and intensity pattern along the jet in all the higher bands. Dust cannot plausibly scatter the X-rays seen, but Thomson scattering fits all bands well
