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 ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

A series of recent observations is bringing the large-scale dark matter scaffolding of the cosmos into sharper observational focus, using techniques that range from gravitational lensing to radio ...

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.

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 ...

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 ...

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

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

A recent paper reveals we're almost certainly going to collide with a galaxy in the next couple billion years, but it's not the one we thought. Reading time 2 minutes For over a decade, researchers ...
