Cosmological simulations have become indispensable tools for understanding the assembly of galaxies within the framework of a ΛCDM Universe. By numerically integrating the coupled equations of gravity ...

The study challenges assumptions that galaxies are too vast to be affected by small changes.

This animation shows the simulated evolution of a galaxy over 200 million years. While the simulations look very similar with and without the machine learning AI model, the AI model performed 4 times ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

In a feat of galactic archeology, astronomers are using ever more detailed information to trace the origin of our galaxy—and to learn about how other galaxies formed in the early stages of the ...

When scientists viewed the James Webb Space Telescope’s (JWST) first images of the universe’s earliest galaxies, they were shocked. The young galaxies appeared too bright, too massive and too mature ...

The FLAMINGO project helps scientists explore how galaxies, dark matter and cosmic structures evolved over billions of years.

If you’ve ever been to a place with minimal light pollution and looked skywards at nighttime, you’ve probably seen our Milky Way galaxy. It manifests as a thick, hazy band of stars streaking across ...

Cosmological hydrodynamics and galaxy formation simulations combine gravitational dynamics with fluid physics to model the growth of structure from the early Universe to the present day. By solving ...
