Astronomers Witness Explosions Of Extremely Powerful Black Holes In Clusters Of Distant Galaxies

Astronomers witness explosions of extremely powerful black holes in clusters of distant galaxies

Astronomers using the NASA X-ray Observatory have observed unusual outbreak activity in the center of SPT-CLJ0528-5300 (abbreviated SPT-0528), a cluster of galaxies about 6.7 billion light years away

Clusters of galaxies are some of the largest cosmic structures, joined by the combined gravitational bridge of its components. There are thousands of galaxies of all ages, sizes and shapes.

Typically, the mass of galaxy clusters is approximately one million billion times the mass of the Sun, and often extends over several million light years.

They form over billions of years as small clusters of galaxies join slowly and are generally in the group of so-called superclusters, the so-called high-level strata of the structure.

The largest cluster in the nucleus of most galaxy clusters is called a galaxy, which consists of a demonic black hole.

These black holes undergo a period of feeding, where they collect plasma from a group, followed by a period of explosive detonation, where they shoot a stream of plasma after reaching its filling.

“This is an extreme case of the outbreak phase,” said Michael Calzadilla, a graduate student at the MIT Kavali Institute for Astrophysics and Space Research, regarding the SPT-0528 observations.

According to the team, when the plasma in the central galaxy of SPT-0528 leaves a supermassive black hole, it pushed the material out, creating two large cavities 180 degrees from each other.

By mixing the volume and pressure of the displaced gas with the age of the two cavities, Calazilla and his colleagues were able to calculate the total energy of the outbreak.

With more than 1054 joules of energy, it is the most powerful black hole outbreak observed in a distant cluster of galaxies.

“Because the galaxy clusters are full of gas, the first theories about them predicted that as the gas cooled, the clusters would see a higher rate of star formation, which would require the formation of silent gas,” they said. Astronomers Said

“However, these clusters are not as quiet as expected and, as such, are not producing new stars at the expected speed. The gas was prevented from cooling completely.”

“The culprits were supermassive black holes, whose plasma flow produces gas in the clusters of galaxies, which quickly heat up to form stars.”

Astronomers have considered the process of cooling gas and releasing hot gas from a black hole as a balance that maintains the constant temperature in the cluster of galaxies.

“It’s like a thermostat,” said Dr. Michael Macdonald, also of the MIT Kavali Institute for Astrophysics and Space ResearchHowever, the black hole outbreak in the galaxy cluster SPT-0528 is not in equilibrium.

“If you observe the power exerted by the black hole as the gas cools, the outbreak is very high, so the outbreak is very high. The outbreak SPT-0528 is a defective thermostat,” said Calzadilla. Said

“It seems you have cooled the air to 2 degrees, and the thermostat’s response was to heat the room to 100 degrees,” said Dr. McDonald. An article on the findings has been published in the Astrophysical Journal Letters.

Extremely powerful black hole astronomers explode in clusters of distant galaxies: astronomers using NASA’s X-ray Observatory have observed an unusual outbreak activity in the center of SPT-CLJ0528-5300 (abbreviated SPT-0528), which is approximately 6.7 Billion is a cluster of galaxies. A light years away.

Clusters of galaxies are some of the largest cosmic structures, which connect to the combined gravitational bridge of its components. There are thousands of galaxies of all ages, sizes and shapes.

Typically, the mass of galaxy clusters is approximately one million billion times the mass of the Sun, and often extends to several million light years. They form over billions of years as small clusters of galaxies slowly join together and typically form clusters of so-called superclusters.

Which are called high-level structure levels. The largest cluster in the nucleus of most galaxy clusters is called a galaxy, which consists of a demonic black hole.

These black holes go through a period of feeding, where they collect plasma from a group, followed by a period of explosive explosion, where they fire a plasma stream after filling. “This is an extreme case of the outbreak phase,” said Michael Calzadilla, a graduate student at the MIT Kavali Institute for Astrophysics and Space Research, regarding comments from SPT-0528.

The galaxy cluster SPT-0528 is not in equilibrium. “If you observe the power emitted by a black hole because the gas is cold, its outbreak is very high, so its outbreak is very high.” SPT-0528 is a bad thermostat, “McDonald said.

He said. It seems you have cooled the air to 2 degrees, and the thermostat’s response was to heat the room to 100 degrees. Find the findings in the Astrophysical Journal. It has been published in Etrs.
