Above a certain threshold, galaxies stop growing , no matter how much raw material they have on hand. The question is: what ...

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 ...

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 ...

An international research team led by Chinese scientists at the National Astronomical Observatories of the Chinese Academy of ...

Image: Snapshots of the time evolution of a collision of two spiral galaxies with black holes at their center from a computer simulation. Color indicates temperature and brightness the gas density.

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...

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 ...

Ring galaxies and polar-ring galaxies offer natural laboratories for investigating how dynamical processes shape star formation. In collisional ring systems, a near head-on encounter launches a ...
