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 ...

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.

A universe evolves over billions upon billions of years, but researchers have developed a way to create a complex simulated universe in less than a day. The technique, published in this week's ...

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 ...

(Nanowerk News) Humans have long tried to explain how stars came to light up the night sky. The wide array of theories throughout history have one common (and correct) governing principle that ...

CHICAGO—Tiziana Di Matteo, associate professor of physics at Carnegie Mellon University is harnessing the power of supercomputing to recreate how galaxies are born, how they develop over time and, ...

The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic ...

The background image shows the present-day distribution of matter in a slice through the largest FLAMINGO simulation, which is a cubic volume of 2.8 Gpc (9.1 billion light years) on a side. The ...

Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with ...

An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the ...
