The Observer’s Guide to the Gamma-Ray Burst Supernova Connection

Figure 3

A mosaic of GRB-SNe (AG + SN). Clear SN bumps are observed for all events except SN 2003dh, for which the SN’s properties had to be carefully decomposed from photometric and spectroscopic observations [7]. The lack of an unambiguous SN bump in this case is not surprising given the brightness of its AG relative to the other GRB-SN in the plot: SN 2013dx was at a comparable redshift (, compared with for 2003dh), but its AG was much fainter (2–5 mag) at a given moment in time. The redshift range probed in this mosaic spans almost an order of magnitude () and shows the variation in peak observed magnitude for GRB-SNe. It is important to remember that given the large span of distances probed here, observer-frame -band samples a wide range of rest-frame SEDs (from -band to -band).
