In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter. When two galaxies merge ...

Hubble's new image of galaxy cluster Abell 209 reveals over 100 galaxies and gravitational lensing effects from dark matter ...

A new study suggests that the orderly arrangement of the Milky Way's satellite galaxies may be a coincidence; if the research holds up, it could undermine our understanding of dark matter.

A massive clump of dark matter in the Perseus galaxy cluster is linked to its core by a bridge of dark matter, evidence of a history of mergers.

Dark energy camera captures galaxies in lopsided tug of war, a prelude to merger Haley's Coronet and dwarf galaxy companion feel each other's gravitational forces as they begin to coalesce Date ...

Most importantly, collisionless dark matter has difficulty producing the observed number of dwarf satellite galaxies and matching the observed densities in the cores of galaxies.

Dark matter could act as a cosmic matchmaker between dark matter and merging supermassive black holes, solving astronomy's "final parsec problem." ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

Campus News Scientists to study nearby galaxies for galactic-formation history, dark matter At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing ...

Supermassive black holes sometimes merge, but for decades, astrophysicists have not known how. Now, we may finally have a solution in the form of dark matter. After a pair of galaxies smash ...
