Cosmic Oddity Explained: Astrophysicists Discover Why Our Supergalactic Plane Lacks Spiral Galaxies

Cosmic Oddity Explained: Astrophysicists Discover Why Our Supergalactic Plane Lacks Spiral Galaxies
Share on FacebookShare on Twitter

Milky Way Galaxy

Astrophysicists have discovered why spiral galaxies like the Milky Way are rare in the Supergalactic Plane, a dense region in our Local Universe. The research, led by Durham University and the University of Helsinki, used the SIBELIUS supercomputer simulation to show that galaxies in dense clusters on the Plane often merge, transforming spiral galaxies into elliptical ones. This finding, which aligns with telescope observations and supports the standard model of the Universe, helps explain a long-standing cosmic anomaly about galaxy distribution.

Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane.

The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across in which our own Milky Way galaxy is embedded.

While the Plane is teeming with bright elliptical galaxies, bright disk galaxies with spiral arms are conspicuously scarce.

Now an international team of researchers, co-led by Durham University, UK, and the University of Helsinki, Finland, say different distributions of elliptical and disk galaxies arise naturally due to the contrasting environments found inside and outside the Plane.

Galaxy Evolution in Dense Clusters

In the dense galaxy clusters found on the Supergalactic Plane, galaxies experience frequent interactions and mergers with other galaxies. This transforms spiral galaxies into elliptical galaxies – smooth galaxies with no apparent internal structure or spiral arms – and leads to the growth of supermassive black holes.

By contrast, away from the Plane, galaxies can evolve in relative isolation, which helps them preserve their spiral structure.

Innovative Simulations and Key Findings

The findings are published in the journal Nature Astronomy.

The Milky Way is part of the Supergalactic Plane, which contains several massive galaxy clusters and thousands of individual galaxies. The vast majority of galaxies found here are elliptical galaxies.

The research team used the SIBELIUS (Simulations Beyond the Local Universe) supercomputer simulation, which follows the evolution of the Universe over 13.8 billion years from the early Universe to the present day.

Distribution of the Brightest Galaxies in the Local Universe

Both panels show projections in supergalactic coordinates, out to approximately 100 Megaparsec (Mpc).

While most cosmological simulations consider random patches of the Universe, which cannot be directly compared to observations, SIBELIUS aims to precisely reproduce the observed structures, including the Supergalactic Plane. The final simulation is remarkably consistent with observations of our Universe through telescopes.

Contributions and Implications of the Research

Research co-author Professor Carlos Frenk, Ogden Professor of Fundamental Physics, in the Institute for Computational Cosmology, Durham University, said: “The distribution of galaxies in the Supergalactic Plane is indeed remarkable.

“It is rare but not a complete anomaly: our simulation reveals the intimate details of the formation of galaxies such as the transformation of spirals into ellipticals through galaxy mergers.

“Further, the simulation shows that our standard model of the Universe, based on the idea that most of its mass is cold dark matter, can reproduce the most remarkable structures in the Universe, including the spectacular structure of which the Milky Way is part.”

The peculiar separation of spiral and elliptical galaxies in the Local Universe, which has been known about since the 1960s, features prominently in a recent list of “cosmic anomalies” compiled by renowned cosmologist and 2019 Nobel laureate Professor Jim Peebles.

Research lead author Dr. Till Sawala, a postdoctoral researcher at Durham University and at the University of Helsinki, said: “By chance, I was invited to a symposium in honor of Jim Peebles last December at Durham, where he presented the problem in his lecture.

“And I realized that we had already completed a simulation that might contain the answer. Our research shows that the known mechanisms of galaxy evolution also work in this unique cosmic environment.”

The supercomputer simulations were performed on the Cosmology Machine (COSMA 8) supercomputer, hosted by the Institute for Computational Cosmology at Durham University on behalf of the UK’s DiRAC High-Performance Computing facility and on CSC’s Mahti supercomputer in Finland.

The research was funded by the European Research Council, the Academy of Finland and the UK Science and Technology Facilities Council.
