New Study Reveals Rareness of Spiral Galaxies in Supercluster
A recent study conducted using supercomputer simulations has shed light on the rareness of spiral galaxies within the Local Supercluster on the supergalactic plane. The findings, published in the journal Nature Astronomy, suggest that the scarcity of spiral galaxies, such as the Milky Way, in the plane is due to frequent galaxy collisions that have transformed them into elliptical galaxies.
The Local Supercluster, a vast cosmic structure containing thousands of galaxies, is a pancake-shaped arrangement of several huge galaxy clusters. However, despite its size and density, the distribution of galaxies in the supergalactic plane is unusual. The simulations carried out by researchers revealed that spiral galaxies in dense clusters often collide with each other in catastrophic collisions. This collision process results in the transformation of spiral galaxies into elliptical galaxies, with their fragile spiral arms being smoothed out.
The team of researchers, using the Simulations Beyond the Local Universe (SIBELIUS) supercomputer, built a model that traced the observed evolution of galaxies back to the beginning of the Big Bang 13.8 billion years ago. The simulations accurately reproduced the evolution process, identifying the mechanism by which spiral galaxies are transformed into elliptical galaxies due to galaxy mergers.
The study also found that the process of collision pushes material against the supermassive black hole of the collided galaxy, causing the black hole to become even larger. This contributes to the prevalence of elliptical galaxies within the Local Supercluster.
The researchers are now working to further improve the simulations and make them more accurate in order to compare the findings with telescopic observations. The study’s results were found to be consistent with observations, providing valuable insights into the formation and evolution of galaxies within the supergalactic plane.
The new understanding of the rarity of spiral galaxies in the supergalactic plane has opened up new avenues for further research in the field of astronomy. It also highlights the importance of advanced simulations and computational models in understanding complex cosmic phenomena.
