After Decades of Searching, Scientists Make a Major Breakthrough in the Mystery Surrounding Our Galaxy’s Black Hole

Every large galaxy shelter Supermasive black hole At the center of it, everyone emits a strong wind of hot gas from the horizon of his event. Our Galaxy Should There will be no exception. Nevertheless, for the past 50 or so, astronomers have been looking for the wind coming from the black hole at the center of Milkyo and they could not find anything at that time. Not even gentle air.

So far In the initial study, a group of scientists give details the most powerful evidence found in the air flowing from the black hole of Milkyo, Sagittarius A*The Breakthrough Search, Posted on Preprint Server Arxative In September, describe a large, cone-shaped area around the black hole where cold gas seems to have been blown.

“If this is true, it will be very exciting withdrawn with a number of extensive influences for the center of the galaxy,” the postdotorral astrophysist of the University of Maryland, who was not involved in this study, said he said ScienceThe Although he notes that the missing gas is an indirect evidence of the air of the black hole, the search is a major step in solving this case.

The victim for the wind of the bow

In contrast to popular beliefs, the black holes are not just sucking everything that comes very close. Gas spirals on the disk of the ingredients surrounded by a supermasive black hole are as heated. Through a complex combination of magnetic, radiation and thermal effects, some air or plasma of this gas comes out in the form of high-speed jets.

The air of a supermasive black hole is so strong, they shape how its host galaxy develops. For example, astronomers know that the air helps keep interground gas warm and suppress the star formation, limiting the galaxy to grow very large. Understanding how these dynamics are playing in the center of Milkywa is the key to knowing how it developed over time and identifying our own original story.

Many astronomers have sought the wind of A*, but the previous binoculars observations have received anti -the results, because it is only hard to overcome the galactic nucleus through all the gas, dust and stars.

In this new study, however, a new telescope in Chile has arrived at the event. Atacama Large Millimeter/Submilimeter Array (Alma) is the world’s most powerful radio telescope. By comparing it with optical telescopes, it is exceptionally good for the entry of dust cloud.

How did they do it

Both astronomer Lena Churchicova and astronomer Mark Gorceki, both northwestern universities, to create an unprecedented detail of bowing molecular gas with sophisticated data processing techniques with almost five years of alma observation.

This map has revealed a cone -shaped gap of cold gas clouds. When researchers covered their maps in X-ray data collected by NASA’s Lunar X-ray observatory, it is fully matched to the size of the cone. The alignment suggests that the hot plasma derived from the bow is removed the cool gas and the X-ray is emitted in the process.

In order to solve the mystery of Sagitarius A*the missing winds of the scientists bring closer to scientists than ever, but the case is not Quarrel Direct proof such as measuring the velocity of the exterior of the particle from the black hole is still proven. But by closing the answer so significantly, astronomers are still pushing our galaxy’s mysterious heart to understand.
