Astronomers at the University of California, Irving studied the galaxy NGC 7469 using the ultra-sensitive mid-infrared instrument of the James Webb Space Telescope. Scientists conducted a detailed analysis of the interaction between the core of active galaxies dominated by supermassive black hole and the surrounding areas where the star birth process occurs .

One of the most interesting processes in life in galaxy is the interaction of its core with the surrounding space . " James Webber " gives us humans the opportunity to see it.
A team of astronomers from the University of California, Irving used the James Webb Space Telescope to explore the galaxy NGC 7469. This galaxy is 228 million light-years away from Earth. Astronomers analyzed the interaction between the core of an active galaxy dominated by supermassive black holes and the surrounding area, where the star formation process is actively underway.
Main author Vivian Wu said "We not only saw the wind from the supermassive black hole, but also the 'impact heating' of the gas caused by this wind near the core of the Milky Way.
Vivian Wu points out that when the wind from the black hole in the center of Milky Way presses on the dense gas around it, heating occurs, resulting in shock wave fronts. According to her, this effect can affect the formation of stars in two opposite ways: by compressing the gas, it helps the birth of new stars, but wind can also destroy new stars.

NGC 7469 is a bright galaxy with an active center with a supermassive black hole and a star forming a regional ring. For decades, astronomers have tried to study the detailed dynamics of these galaxies. They make up about 10% of all galaxies in the universe, but their centers are obscured by dust. Now, James Webb (James Webb) gives astronomers the opportunity to see what is lurking behind the dust screen.
"In this system at least, we now have a clearer picture of how an active galaxy nuclear replaces gas, and how it affects the surrounding matter" Vivian Wu adds.
NGC 7469 A significant contribution to the dynamics of motion is made by a galaxy close to it, which merges with it.
" interaction with another galaxy means that the galaxy matter moves due to tidal forces and is attracted to the center of the galaxy. This process causes the center of the Milky Way to become very dusty," said Vivian Wu, "that's why instruments like James Webber need so much. They allow us to see through the dust and make it easier to understand the dynamics of merger galaxy nuclei .
