Distribution of dwarf galaxies surrounding the MATLAS host NGC3694. Left: MATLAS color image centered on NGC3694 (red circle). The identified dwarf galaxies from Habas et al. (2020) are circled in yellow. The background galaxy Mrk 423 is highlighted by the pink circle. Right: Zoom-in on the region (orange box) around Mrk 423, showing the spatial clustering of the identified dwarfs around it. Image from the MATLAS survey (Duc et al. 2013).
