New simulations are providing the most realistic pictures yet of how galaxies formed and evolved from the beginning of time.

The older stars migrated out from the galactic center, leaving the younger ones inside.

That uncertainty has made one question especially stubborn for astronomers: where does the galaxy’s star-forming disc ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just been announced. A team ...

For years, computer simulations of the earliest galaxies have struggled to match what telescopes actually show. Depending on ...

How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at ...

This equation, representing the gradient of a space-phase pressure field, is shown to describe not only motion within ...

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its ...

Leiden scientists lead COLIBRE, a groundbreaking set of cosmological simulations. By including key missing physics, cold gas and cosmic dust, they ...

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of “failed” galaxies — clumps of dark matter that captured gas but never birthed a star. Because they ...
