Supermassive Black Hole Erupted Near Earth and Scientists Capture the Event

By: April Carson



The most comprehensive and detailed image of the relativistic jets of the active galaxy Centaurus A in the radio spectrum has been created by astronomers. Scientists not only studied the structure of jets and determined how fast material is being ejected from the galaxy's core, but they were also able to produce a mathematical model for the galaxy's matter dynamics.


Everything you need to know about Centaurus A


The radio galaxy Centaurus A is a gigantic elliptical galaxy that is located at about 12 million light-years from Earth. The active galactic nucleus, which contains a supermassive black hole with a mass of 55 million Suns, is hidden from the terrestrial viewer in the optical spectrum owing to thick dust clouds, but it radiates strongly in X-ray and radio frequencies.


In the distant past, a huge elliptical galaxy smashed head-on into a tiny spiral, causing the strange form and burst of star birth in this galaxy.



The galaxy's relativistic jets of plasma (jets), tens of thousands of light-years long, are one of the most fascinating features. The activity of a supermassive black hole is to blame for the formation of these flows, which are tens of thousands of light-years lengthy. They've previously been observed with the Event Horizon Telescope, which obtained detailed images of them as well as numerous space and ground-based telescopes.


The data they have collected allows us to understand the mechanisms of jet creation and how they interact with the galaxy's environment.


Scientists constructed the most detailed image of the relativistic jets of Centaurus A


The findings of a study of Centaurus A using the low-frequency ground-based radio telescope MWA (Murchison Widefield Array) at 185 megahertz and with an angular resolution of one and a half arc minutes were presented by Benjamin McKinley of Curtin University, along with a colleague. The most complete radio image of the galaxy's jets has revealed a number of previously unknown jet features, according to scientists.



The jets of Centauri A, as they leave the core, develop into enormous emitting regions - radio lobes, each of which is made up of an inner (brighter) and an outer part with a fibrous structure. During the acceleration of electrons in shock waves or the collision of electrons with magnetic fields, radiation stains (nodes) may be observed near the nucleus, which appear in front of heated gas clouds releasing in the X-ray range.


The researchers conclude that the remnants of a small galaxy destroyed by tidal forces are concentrated in the northern radio field.


Additional discoveries and calculations


The rate of material loss from the core of Centaurus A into the halo is about 1,100 kilometers per second, and mass outflow is 2.9 times that of the Sun each year. Matter accretion onto a black hole occurs at a rate of 5.3 × 10 -4 solar masses every year.


The galaxy is most accurately characterized by a model in which the hot plasma halo cools and condenses, forming icy clouds of gas that fall into the core area. Most of the gas is ejected from the galaxy via jets or outflows, which, as they grow, transport more and more material with them.
