Can gas escape from a very large gravity grasp? Black Hole Are you forming a “tsunami” in space?
In a new NASA-funded study, astrophysicists used computer simulations to model the environment around a supermassive black hole in deep space. They discovered that a huge tsunami-like structure could have formed near these black holes.They even think of it Supermassive black hole You can host the largest tsunami-like structure in the universe.
“It’s the laws of physics that can explain things here in space and even far outside black holes,” said Daniel Proga, an astrophysicist at the University of Nevada, Las Vegas (UNLV). It was. Said in a NASA statement..
In this study, researchers explored the strange environment around a supermassive black hole and how gas and radiation interact there.
Supermassive black holes have large disks of gas and matter that swirl around them and over time. Active galactic nucleus.. These systems often emit a jet of matter, emitting bright, glowing x-rays onto a disc that is out of the reach of gravity in a black hole. This X-ray radiation pushes the wind flowing from the center of the system. This is called a “spill”.
this X-ray radiation Researchers also believe that it may help explain the denser gaseous regions in the environment around supermassive black holes called “clouds.”
“These clouds are ten times hotter than the surface of the sun and move at the speed of the solar wind, so they are exotic objects that you don’t want to fly,” said lead author Dr. Tim Waters. UNLV, a guest scientist at the Los Alamos National Laboratory in New Mexico, said in the same statement.
In computer simulations, the team showed how the atmosphere of a disk rotating around a black hole begins to form waves of gas and material when it is far enough away from the black hole and out of reach. With the addition of outflows pushed out by X-ray radiation, these waves can grow into huge tsunamis.These swirling gas waves can extend up to 10 Light year On the disc, the researchers found it. Once these tsunami-like structures are formed, they are no longer affected by black holes. gravity, According to the statement.
In these simulations, researchers showed how bright X-ray radiation near a black hole penetrates into a pocket of hot gas outside the disk. These hot plasma bubbles expand to nearby cooler gases at the edge of the disc, helping to spur tsunami-like structures. Bubbles also block outflowing wind and swirl into separate structures up to light-year size. These lateral structures are known as the Karman vortex streets. This is a weather pattern that also occurs in the following locations: Earth (On Earth, this pattern of swirling vortices Looks quite different.. )
The Kalman Vortex Street is named after the Hungarian-American physicist Theodore von Kalman. Earth’s atmosphere And space.
According to the statement, this study goes against previous theories suggesting that clouds of hot gas near active galactic nuclei form spontaneously due to fluid instability. This study also contradicts the previous notion that a magnetic field is needed to move colder gas from the disc around a supermassive black hole.
Currently operating satellites cannot confirm their work, but the team hopes to enhance their findings with future research and hopefully telescope observations.Furthermore, observation of plasma near the active galactic nucleus of NASA Chandra X-ray Observatory And of the European Space Agency XMM-Newton According to a NASA statement, the space telescope is in line with the team’s findings.
