At the beginning of our world’s history, something strange happened. Studying what is in the database, scientists now know that there is between a galaxy and a quasar (the distances used by black holes about a billion times the size of our sun). .)
Researchers have called the substance in a new study, called GNz7q, “the ancestor of a supermassive black hole,” because 750 million were formed. years after the Big Bang, which rocked our planet 13.8 billion years ago.
“What is seen connects the two populations of celestial bodies, namely earth starbursts and luminous quasars, and therefore provides a new way of understanding the rapid growth of celestial bodies. supermassive black hole in the first world, ”said Seiji Fujimoto, lead author, a postdoctoral fellow. at the Niels Bohr Institute, University of Copenhagen, spoken in a university language.
Pili: The best Hubble Space Telescope images of all time!
The team found out what was in the archive data collected by the Hubble Space Telescope through a program called the Great Observatories Origins Deep Survey (GOODS), which connects Hubble and space observers. Others look at the deep universe, such as the Space Telescope Research Institute in Baltimore, which uses Hubble.
It is common to get new information from revised archive data with the latest technologies and features, but it is always strange because it is in a well -studied part of the sky. called GOODS North.
“The GNz7q is a unique technology that has been seen at the center of a well -known and well -educated space station – it shows that important information can often be hidden in front of you,” said Gabriel Brammer, author of the study. new. and an observer at the Niels Bohr Institute of the University of Copenhagen, said in a statement. “The availability of GNz7q in a small GOODS-North research area may not be just‘ luck of luck ’, but the prevalence of such causes is much higher than previously thought. “
GNz7q is in a strong star birth zone, in a galaxy that is forming stars about 1,600 times faster than our own galaxy, the Milky Way. When these stars are formed, they emit into the cosmic earth, where the galaxy emits infrared light – a brightness that is brighter on its earth than any other in its era, he said. researchers in the same language.
The researchers believe GNz7q is a stage of change not seen in the first period of global history. The reason is that it can tell scientists more about the evolution of supermassive black holes, because it may also show how the gas and dust interact with each other. can stimulate the growth of a black hole, the company said.
“Although luminous quasars were first seen in the early stages of the universe, the rate of change of the rapid growth of the black hole and its star-star army was not known at the same time,” he said. Brammer at the University of Copenhagen. To say.
Because the properties of GNz7q are closely related to the concept, Brammer added, the signals “GNz7q is the first example of the transformation, the rapid growth of black holes in the ground star base, an ancestor the last supermassive black hole. “
The team plans to look for more data from high -resolution research, as well as future information from the James Webb Space Telescope that first sees light around June.
“A full description of these objects and testing their evolution and under -physics in greater detail is possible with the James Webb Telescope. Once in normal operation, it is available Webb has the power to determine the nature of these rapidly growing black holes, ”Fujimoto said.
A study of the research was published in Nature on Wednesday (April 13).
