The black hole of the heart of the Milky Way does not fall asleep. Instead, the rings of the plasma surrounding it were constantly blinking and drilled by the Super Bright Flare.
Astronomers used the James Web Space telescope to observe SGR A*and disk at once for a year from April 2023 to April 2024. This was the longest consecutive observation in Galaxy’s centralized black hole.
Farhad Yusef-Zadehh, the astrophysical physicians of Northwestern University in Evanston, Evanston, revealed a “constant bubble ring” that has been changed every second or minute in the light of the disk. It releases blind flare blindlyYusef-Zadeh and colleagues report on February 20th Celestial Physics Journal.
The initial black hole, called Sagittarius A* or SGR a*, is about 4 million times more than the sun and is about 26,000 light years in the solar system. Black holes are quite quiet in most times, sometimes bend the material nearby and suffer from light and energy rupture.
But it does not mean that it is lying there. According to the initial observation, including the first image of the black hole, the white hot disk around the plasma is constantly blinking. The computer simulation of how the material flow of the material flowing in the Accetion Disk predicts that the brightness of the disk should be different every few minutes. The new observation not only checks such ideas, but also reveals a blinking work.
JWST has some advantages compared to other telescopes, allowing the disk volatility. Since the telescope is not in the orbit of the earth, the earth can never interfere, so the telescope can be seen longer. You can also observe two different wavelengths of light objects.
Yusef-Zadeh said, “We can see things in color, not black and white.
Yusef-Zadeh thinks researchers have two processes at work. The turbulence of the disk itself causes bubble ring. On the other hand, the process behind a large flare can be similar to the magnetic reconciliation event that collides with two lines of the magnetic field and releases energy bursts. This event also occurs in the sun flare.
The team requested more details with JWST for a 24 -hour observation time.
