ICRAR astronomers (International Center for Radio Astronomical Research) capture a complete picture of an object’s explosion from a radio broadcast. Black Hole The extent is close to Earth, and its apparent size (seen from Earth) corresponds to sixteen adjacent moons.

In many science fiction universes, Black Holes Inspiration. They are the source of mystery and imagination. One wonders what in particular is “beyond”. Natural astronomy December 23, 2021.

The radio broadcast is passed through a central black hole. Galaxy Centaurus A was separated from Earth by about 12 million light-years. This is the radio galaxy closest to the Milky Way. Seen from Earth, the eruption is equivalent to sixteen moons located side by side (which extends eight degrees in the sky).

A disc formed around the black hole

According to Dr. Benjamin McKinley reveals the captured image spectacular new details from the Centaurus A Galaxy radio broadcast.These radio waves come from objects absorbed in the largest black hole in the center of the galaxy. », He explains Was contacted.

It forms a disk around the black hole, and as it approaches, the material splits and forms powerful rays on each side of the disk that propel most of the material into space. Light year .

The black hole eats the falling gas and emits matter at speeds close to the speed of light, causing “radio bubbles” to form over hundreds of millions of years. One such “bubble” was captured by the Murchison Whitefield Array Telescope (MWA), located in the interior of Western Australia.

According to the researchers, previous radio observations could not handle the extreme brightness of jet planes and changed the details of the larger area around the galaxy, but our new image went beyond these limits. Details that allow scientists to “learn a lot about Centaurus A”.

To capture the best image, the researchers combined their radio observations with optical and X-ray data. It helps to better understand the physics of these giant black holes Says McKinley.

MWA may collect “abnormal amounts of data”

For Professor Steven Dingke, director of MWA, this observation was made possible by the telescope’s larger vision. MWA is the forerunner of another radio telescope, the more sophisticated SKA (square kilometer line) to be built in Western Australia and South Africa.

The larger the field of view, the more extraordinary data we can collect, the greater the potential for detecting each MWA display. This is a great step towards an even bigger SKA. .

The McKinley-led study confirms a new theory, the rise in the confusing cold. According to Massimo Caspari, an astronomer at the Italian National Institute of Astronomy, ” In this model, cold clouds condense in the galaxy, raining in the central regions and nourishing the largest black hole. .

The galaxy appears brighter in the middle, where it is more active and more energetic. When you walk away, the light disappears because energy is lost and ” Things calm down », Transparent McKinley. ⁇ But there are some interesting features that cause the charged particles to accelerate again and interact with strong magnetic fields. , concludes the scientist.
