Scientists track gas flow around active black holes

Japanese scientists use a Chilean telescope to observe a chaotic region around an active black hole in a nearby galaxy. For the first time, the researchers were able to track and measure the magnitude of the flow in all its stages, including atoms, molecules and plasma. The scientists also determined that accretion flows are produced by a mechanism called gravitational instability.”

Supermassive Black Holes in Circinus Galaxies

Researchers at Tohoku University in Japan observed the Circassian Galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA) astronomical observatory in the northern Chilean desert. Like most galaxies, a supermassive black hole lurks at the core of the Circinus galaxy, one of the closest galaxies to the Milky Way. The supermassive black hole is actively feeding, surrounded by a ring of inward-spinning gas and dust, the tormented material glowing brightly at all wavelengths due to extreme friction. This is known as an active galactic nucleus or active galactic nucleus. Active black holes are also known as bright black holes.

Black holes play with food

The researchers also observed that instead of feeding on a large portion of the accreted material, the supermassive black hole actually plays with its food. Most of the gas is expelled back into the accretion disk, similar to the flow of water in a fountain. The amount of material delivered to the supermassive black hole is about 30 times the amount of material needed to sustain an active galactic nucleus. The researchers also observed that the disk is too massive to maintain the shape maintained by the pressure of its motion and collapses under the influence of its own gravity, creating a complex structure that causes the material to fall rapidly towards the supermassive black hole, a process known as “gravitational instability”.

Importance of research

In order to fully understand the growth of supermassive black holes throughout the history of the Universe, it is necessary to study various types of supermassive black holes that are far away from us. This requires high-resolution and high-sensitivity observations, and we have high expectations for the continued use of ALMA and the upcoming next-generation Large Radio Interferometer.”
