Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent ...

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

The group of Prof. Habouzit has strong theoretical expertise in the formation and evolution of galaxies and their massive black holes (MBHs), as well as advanced simulation modeling.

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

Few scientific ideas have leapt from philosophy seminars to dinner-table debates as quickly as the claim that our universe might be an artificial construct. The simulation hypothesis promises a ...

A sheet of dark matter lying beyond the boundary of the Local Group is responsible for this.

The consortium running the European Space Agency's (ESA) Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms developed by UZH ...

A flat plane of dark matter beyond the Local Group may explain why nearby galaxies move away from us instead of falling ...

New analysis by Francesca Capel and Nadine Bourriche narrows possible sources of the Amaterasu cosmic ray, suggesting nearby galaxies like M82 rather than the Local Void.
