Possible interacting system of GAMA 526784 and a putative companion, separated by 48 kpc in projection. Young star clusters in GAMA 526784 align along the axis possibly connecting the galaxies, with their ages and the star formation history of the galaxy suggesting formation during a close encounter ∼100 Myr ago. This spatial and possibly kinematic configuration provides compelling evidence of a physical association between the galaxies. The image is 12 arcmin on the side. North is up, and east is to the left. The only massive galaxy close in projection to GAMA 526784 is PGC 025165 (highlighted by the dotted rectangle), and it lies at a redshift of z = 0.0391, i.e. far in the background.
