Figure 3

Our preferred model (red line) is able to self-consistently reproduce the observations (symbols) during three distinct phases of the supernova evolution, with different characteristic timescales and dictated by different physical properties: the shock-breakout phase, the post-shock cooling peak and the radioactivity-powered peak. Note the logarithmic scale for the time axis.
