Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By weaving together quantum theory, astrophysical data and high precision sensors, ...

Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Milky Way simulations show stellar streams can develop dark matter-like gaps and kinks without encounters with dark matter clumps.

Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like ...

Cosmological simulations of dark matter halos form the backbone of our understanding of large-scale structure in the Universe. By numerically evolving millions to billions of particles under gravity, ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic ...

Galactic simulations show stellar streams develop dark-matter-like irregularities without dark matter clumps, helping distinguish false signals from real ones. (Nanowerk News) Most of the stars in our ...

Long ribbons of stars loop around the Milky Way far beyond the galaxy’s familiar flat disk. Astronomers have hoped that disturbances in these stellar streams could expose something otherwise invisible ...

This is interesting of course, but the article suffers from problems. Besides the missing article link, the linked spiral arm dynamical mass excess observations are not explained by dark matter as it ...

Most galaxies are likely surrounded by long filaments of orbiting stars known as stellar streams. In a new study from the University of Washington, astronomers simulated stellar streams — pictured ...
