Understanding Blended Galaxies

This image shows three instances of merging galaxies located at least a billion light years from Earth. Each galaxy is as large as the Milky Way and contains about 100 billion stars. Violent gravitational interactions created the tidal tails shown and triggered massive black hole accretion at the galactic nuclei. These systems were first confirmed by Hai Fu in 2015.

Astrophysicist wins grant to find and characterize super massive black holes associated with merging galaxies. In roughly 4 billion years, the Milky Way will be no more. Indeed, our home galaxy is on course to collide and unite with the Andromeda Galaxy, at present some 2 million light years away...

Andromeda Galaxy Scanned with High-energy X-ray Vision

NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured the best high-energy X-ray view yet of a portion of our nearest large, neighboring galaxy, Andromeda. The space mission has observed 40 “X-ray binaries” – intense sources of X-rays composed of a black hole or neutron star that feeds off a stellar companion.

The results will ultimately help researchers better understand the role of X-ray binaries in the evolution of our universe. According to astronomers, these energetic objects may play a critical role in heating the intergalactic bath of gas in which the very first galaxies formed...
