A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe.
Surprise: Dwarf Galaxy Harbors Supermassive Black Hole
The surprising discovery of a supermassive black hole in a small nearby galaxy has given astronomers a tantalizing look at how black holes and galaxies may have grown in the early history of the Universe.
VLBA Locates Superenergetic Bursts
Using a worldwide combination of diverse telescopes, astronomers have discovered that a giant galaxy’s bursts of very high energy gamma rays are coming from a region very close to the supermassive black hole at its core. The discovery provides important new information about the mysterious workings of the powerful engines in the centers of innumerable galaxies throughout the Universe.
Black Holes Lead Galaxy Growth
Astronomers may have solved a cosmic chicken-and-egg problem — the question of which formed first in the early Universe — galaxies or the supermassive black holes seen at their cores.
Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe.
Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism — a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies.
