"A starless or 'dark' dark matter halo would have no galaxy at its center." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. For some time, ...

Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), and her team have posted a new paper to the arXiv preprint server ...

Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark matter ...

We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters.

The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly ...

Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own. To wit, the Large Magellanic Cloud (LMC ...

Dark matter halos are the gravitational scaffolds in which galaxies form and evolve, emerging from the collapse of primordial density fluctuations under the influence of gravity. Their internal ...

SANTA CRUZ, CA–Researchers at the University of California, Santa Cruz, have used NASA’s most powerful supercomputer to run the largest simulation to date of the formation and evolution of the dark ...

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, ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

Every galaxy is thought to form at the center of a dark matter halo – a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity ...
