We conducted our cosmological hydrodynamic galaxy formation simulations using the new hydrodynamic code GIZMO 12, which includes a model for the impact of stellar radiative and thermal pressure on the ...

Artist's conception of early starbursting galaxies. UC Davis astronomers collaborated on new simulations showing how bright galaxies could emerge early in the universe. Stars and galaxies are shown in ...

One of the most powerful tools for understanding the formation and evolution of galaxies has been the use of computer simulations–numerical models of astrophysical processes run on supercomputers and ...

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.

"In recent years, scientists have begun to appreciate that the total mass of stars in today’s galaxies corresponds directly to the size of a galaxy’s black hole, but until now, no one could account ...

After 9 months of number crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way emerged from a computer simulation of the physics involved in galaxy formation and ...

Physicists are harnessing the power of supercomputing to recreate how galaxies are born, how they develop over time and, ultimately, how they collapse. Scientists are creating computer simulations to ...

SANTA CRUZ, CA--After nine months of number-crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way emerged from a computer simulation of the physics involved in ...

"Star formation in real galaxies occurs in a clustered fashion, and to reproduce that out of a cosmological simulation is hard," Madau said. "This is the first simulation that is able to resolve the ...

Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself.
