The arcs of light observed around the galaxy are likely caused by a gravitational lensing effect. This effect occurs when the gravitational field of a massive object, such as a galaxy, bends and distorts the light passing through it. As the light from distant objects passes near the massive galaxy, it gets deflected, resulting in the formation of arcs or multiple images. The phenomenon of gravitational lensing provides valuable insights into the distribution of matter and the nature of gravity.
