Indian scientists discovered three huge ‘black holes’

Indian scientists discovered

Indian scientists have discovered not one, but three huge ‘black holes’. All these have been found in interconnected galaxies. This is a rare event and it is clear from the latest study that they are more likely to be observed in galaxy clusters formed after such merger. According to the country’s Department of Science and Technology, huge ‘black holes’ are difficult to detect because they do not emit any light. They are recognized by their effect on the surrounding universe. When a black hole swallows dust and gas, it releases energy and electromagnetic radiation.

 

Indian scientists have discovered not one, but three huge ‘black holes’. All these have been found in interconnected galaxies. This is a rare event and it is clear from the latest study that they are more likely to be observed in galaxy clusters formed after such merger. According to the country’s Department of Science and Technology, huge ‘black holes’ are difficult to detect because they do not emit any light. They are recognized by their effect on the surrounding universe. When a black hole swallows dust and gas, it releases energy and electromagnetic radiation.

The team of researchers from the ‘Indian Institute of Astrophysics’ has done this study in collaboration with researchers from France. From India it included Jyoti Yadav, Moushumi Das and Sudhanshu Barve. He was doing research on AGI 7733 and AGI 7734. They saw something strange emanating from the center of AGI 7734. Something similar appeared bright near the arm of AGI 7733. Its speed was different from that of the Galaxy.

There are also huge black holes at the center of these galaxies. With the merger of two galaxies, the black holes present in them also come close to each other but they cannot merge. In the presence of a third black hole, they transfer their energy to it and mix with each other. Two black holes have been observed in such galaxies, but for the first time three massive black holes have been found. These black holes are produced by the explosion of dying stars or the collision of neutron stars and because of these ‘space-time’ is changed. Their gravitational force is so high that even light cannot come out of them. Researchers have created a map that shows a black hole from a white dot on a black background. This map is published in Astronomy and Astrophysics. 25000 black holes are visible in it, whereas there are more in the universe. The data for this is taken from only four percent of the northern hemisphere’s sky.

The team of researchers has prepared this map with the help of 52 ‘Low-Frequency Telescope’ (LOFAR). These telescopes detect radio emissions from matter moving very close to the black hole. The lead researcher, Francisco de Gasparin, has said that this result has come after many years of hard work on very difficult data. New methods were invented to capture radio signals in the sky. This map has been made by adding 265 hours of data from the sky of the Northern Hemisphere. The Earth’s ‘ionosphere’ layer affects radio waves, making observation difficult. Scientists assumed that it was a small galaxy, which was named NGC 7733N.

In new research, the possibility of such a center of the galaxy which is made of ‘dark matter’ and its edge is also surrounded by low density dark matter. According to its results, the centers of such structures can be so dense that after a limit they turn into black holes. Dark matter refers to such unknown elements that are driven by gravity only by ordinary matter. It neither emits, reflects nor absorbs light. It has never even been directly marked. According to the model of the study, this process would have happened faster than the other models. This would have led to the formation of supermassive black holes in the early universe even before the galaxies in which they are found. Experts believe that 85 percent of the universe consists of dark matter, but no evidence of this has ever been given.
