Spiral arms in a young accretion disk around a baby star

An international research team, led by Chin-Fei Lee at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using ...

Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this ...

The nature of obscured active galactic nuclei

Most galaxies host a supermassive black hole (SMBH) at their nucleus, one whose mass exceeds a million solar-masses. When material actively accretes onto the SMBH, associated processes can produce an active galactic nucleus ...

Black holes stunt growth of dwarf galaxies

Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies ...

Supermassive black hole

A supermassive black hole is a black hole with a mass of the order of between 105 and 1010 solar masses. Most, if not all, galaxies, including the Milky Way, are believed to contain supermassive black holes at their centers.

Supermassive black holes have properties which distinguish them from their relatively low-mass cousins:
