When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way.

Astronomers have discovered a third galaxy without dark matter in a strange string of a dozen dwarf galaxies. A violent ...

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...

The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.
