Chinese astronomers report new findings regarding the central region of a nearby galaxy known as NGC 3319. The researchers found an active intermediate-mass black hole candidate residing in the center of this galaxy. The discovery is detailed in a paper published October 24 on the arXiv pre-print server.

With masses ranging from 100 to 1,000,000 solar masses, the still elusive intermediate-mass black holes (IMBHs) could fill the gap between stellar-mass black holes and supermassive black holes (SMBHs). Given that the origin of SMBHs remains a mystery, IMBHs could be helpful in explaining this puzzle, as the most massive black holes are thought to be grown from much smaller "seeds."

A new supercomputer model could help astronomers find spiraling, merging systems of two supermassive black holes. These mergers happen often in the universe, but are hard to see. Watch as the simulation reveals the merger's brighter, more variable X-rays.
