Comparison between previous and new HST imaging of Dragonfly 44. The left panels show the ACS imaging obtained by P. van Dokkum et al. (2017) and reanalyzed by T. Saifollahi et al. (2021): the upper panel corresponds to the combined F606W image and the lower panel to the shallower F814W image. The large panel on the right shows the new WFC3/UVIS F350LP data presented in this work. All panels are displayed using the same logarithmic stretch to facilitate a direct comparison of depth and surface brightness sensitivity. The new imaging is substantially deeper than the previous data and clearly detects a rich population of compact sources surrounding DF44. Each panel covers approximately 40″ × 40″, corresponding to ∼20 × 20 kpc at 100 Mpc. North is up, and east is to the left.
