| Abstract: |
We present a decomposition of the millimetre-to-radio emission of 3C 273 into several independent outbursts. The decomposition is performed by fitting a set of flares simultaneously to 13 light curves from about 0.3 mm (1000 GHz) to 10 cm (3 GHz), which contain together more than 4000 observations. We show that it is possible to reproduce the detailed structure of the observed light curves of 3C 273 during the last 20 years, with about one outburst per year. This method allows us to isolate individual outbursts and to derive their evolution as a function of both time and frequency. Therefore, we can observe the complete spectral evolution of an outburst. Finally, we test shock models in relativistic jets (like those of Marscher & Gear) by comparing the predicted properties of a flare with the observed properties. |
