The arcs of light around the galaxy are likely a result of gravitational lensing, a phenomenon in which the gravity of a massive object, such as the galaxy, bends and distorts the light from more distant objects behind it. This leads to the formation of arcs and magnified images of those background galaxies as their light is warped by the galaxy's gravitational field.
