An article published in the journal “Nature Astronomy” provides an explanation for the scarcity of spiral galaxies in the so-called Supergalactic Plane. A team of researchers used results obtained from the SIBELIUS supercomputer simulation to offer an explanation based on galaxy mergers. The analysis of the results indicates that in galaxy clusters present on the Supergalactic Plane, interactions and mergers are common with the result that spiral galaxies merge to become elliptical galaxies. Far from the Supergalactic Plane, galaxies are more isolated and therefore less likely to merge.
