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 ...

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 ...

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.

Recent astronomical research indicates that our Earth may be embedded within one of the largest known structures in the ...

(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 ...

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 ...

Supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structure in the universe. Like a celestial beacon, distant quasars make the ...

One of the new high-resolution simulations of the dark matter enveloping the Milky Way and its neighbour, the Andromeda galaxy. The new study shows that earlier, failed attempts to find counterparts ...

Scientists used a supercomputer to perform one of the five largest cosmological simulations ever -- the Last Journey. This simulation will provide crucial data for sky maps to aid leading cosmological ...

(Nanowerk News) An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as ...
