Host galaxy of GRB 050219A compared to other GRBHs and other populations of galaxies (adapted from Hunt et al. 2014). Left: sSFR vs. stellar mass. The host of GRB 050219A (marked in red) lies in a region occupied by ETGs from the GAMA survey (Rowlands et al. 2012, marked in green). The best-studied GRBHs are marked in blue. Right: sSFR plotted against redshift for the GRBH sample from Hunt et al. (2014). The filled circles show the medians of each redshift bin, and the vertical error bars correspond to the upper and lower quartiles of the GRBH distributions. The empty squares show the mean of the GRBH distributions within each redshift bin, and the error bars correspond to the standard deviation. The horizontal error bars are the width of the redshift bins (for the GRBH data).
