A river runs through it: galaxy behavior under environmental mechanisms

■ Natural Sciences / A river runs through it: galaxy behavior under environmental mechanisms Researchers used cosmological hydrodynamic simulations to show consistent behavior patterns in phase-space diagrams. Picture a river. Imagine it—the way the water flows, the way the ripples change when it contacts submerged rocks, the little eddies and whorls that happen near banks and channels. Now, drop a red ball into the river. How is it carried? Does it get caught on the bank? Submerged? Spun in an eddy? Now, picture the universe as a river with all its galaxies as little balls carried in it. In a much simplified version of that … Continue reading A river runs through it: galaxy behavior under environmental mechanismsRead More →
