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 ...

This allowed the team to track the evolution of individual objects in the simulations. “This is rather difficult and is not often done in analyses of cosmological simulations.

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 ...

“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 ...

The project’s first major task will be to model a realistic isolated disk galaxy using various codes and their feedback recipes, varying both the feedback parameters and the resolution. The second ...

A lot of physics goes into the code--gravity and hydrodynamics, star formation and supernova explosions--and this is the highest resolution cosmological simulation ever done this way," said Guedes ...

A realistic simulation of star formation was the key to Eris’s success, Madau said. “Star formation in real galaxies occurs in a clustered fashion, and to reproduce that out of a cosmological ...

Paradox of ultramassive black hole formation solved by supercomputer New simulations reveal that triple galaxy mergers could help explain how the largest black holes in the universe grew so quickly.

This allowed the team to track the evolution of individual objects in the simulations. "This is rather difficult and is not often done in analyses of cosmological simulations.

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 ...

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider ...
