ALMA took the first detailed shot of perturbed gas clouds

US researchers, using the ALMA telescope, took a picture of perturbed gaseous clouds at a distance of 11 billion light-years. This will allow us to study the evolution of early galaxies.

Astronomers obtained the first image of perturbed gaseous clouds in the galaxy at a distance of 11 billion light-years. The team found that the cause of the disturbances is powerful jets that are ejected from a supermassive black hole located in the center of the host galaxy. This study will further help to study the evolutionary process of galaxies of the early Universe.

Scientists already knew that black holes have a strong gravitational effect on surrounding matter. But some black holes that have fast-moving streams of ionized matter have remained little studied. In some nearby galaxies, such jets blow away galactic gaseous clouds, leading to the formation of stars. Therefore, to understand the evolution of galaxies, it is extremely important throughout space history to observe the interaction of jets of black holes with gaseous clouds. However, it was difficult to obtain clear evidence of such an interaction, especially in the early Universe.

To obtain data on this, a team of scientists used the data from the ALMA telescope to observe an object known to MG J0414 + 05З4. A distinctive feature of MG J0414 + 05З4 is that the light that goes from the ground to the Earth is significantly distorted by a different “lensing” that is slightly lower than 0414 + 05З4. “This distortion works as an “authentic telescope”, which makes it possible to study in detail remote objects”, said Takeo Menezaki, an associate professor at the University of Tokyo. “MG J0414 + 05З4 is a great example due to the youth of the jet. I think that our opening paves the way to a better understanding of the evolutionary process of galaxies in the early White”.

Due to such a high resolution, the team found that gaseous clouds along the jets can move at a speed of up to 600 km/s, which indicates the presence of gas exposed. Moreover, it turned out that the sizes of gaseous clouds and jets are much smaller than the typical sizes of a galaxy at this age.
