Physicists explain mysterious dark matter deficiency in galaxy pair
A new theory about the nature of dark matter helps explain why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter, according to a study led by a physicist at the University ...

Researchers study gravitational lensing around an extremely dense galaxy cluster
Dark matter halos are theoretical bodies inside which galaxies are suspended; the halo's mass dominates the total mass. These halos cannot be observed directly, but astronomers infer their presence by the phenomenon of gravity ...
Dark matter 'missing' in a galaxy far, far away
Galaxies and dark matter go hand in hand; you typically don't find one without the other. So when researchers uncovered a galaxy, known as NGC1052-DF2, that is almost completely devoid of the stuff, they were shocked.

ALMA finds massive primordial galaxies swimming in vast ocean of dark matter
Astronomers expect that the first galaxies, those that formed just a few hundred million years after the Big Bang, would share many similarities with some of the dwarf galaxies we see in the nearby universe today. These early ...

New stellar stream discovered by astronomers
(Phys.org)—An international team of astronomers has detected a new thin stellar stream in the halo of the Milky Way galaxy. The newly discovered feature, named "jet stream," could help researchers answer fundamental questions ...
Hydrogen halo lifts the veil of our galactic home
Sometimes it takes a lot of trees to see the forest. In the case of the latest discovery made by astronomers at the University of Arizona, exactly 732,225. Except that in this case, the "forest" is a veil of diffuse hydrogen ...

Dark matter less influential in galaxies in early universe
New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or 'normal' matter. This is in stark contrast to present-day galaxies, ...

In galaxy clustering, mass may not be the only thing that matters
An international team of researchers, including Carnegie Mellon University's Rachel Mandelbaum, has shown that the relationship between galaxy clusters and their surrounding dark matter halo is more complex than previously ...
