For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos ...

A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by ...

"To make progress towards a theory of galaxy formation, it is crucial to compare results and codes from different simulations. We have now done this by bringing together competing code groups behind ...

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.

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 ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. In between all the stars in our galaxy, there is a vast, diffuse mix of gas and dust known as the interstellar medium — and ...

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 ...
