NGC 2315 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure. It also has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
