Even though the event of the Big Bang or the birth of the Universe has only passed a few hundred million years, this puzzle is regarding to be answered soon. After astronomers discovered evidence showing the existence of “Black hole seed” (black hole seed) in the early universe which seeds will grow into these giant black holes is a black hole with a mass of regarding 40 million solar masses. But they originated in a different way from ordinary black holes of modern times, ancient black holes that were the seeds of giant supermassive black holes. It is not caused by the collapse of a dying star. But originated directly from the collapse of a huge gas mass. They are usually located in distant galaxies or galaxies in deep space. which is called Outsize Black Hole Galaxies (OBGs) These OBG galaxies formed in primitive times and are extremely rare. Some of which began to form when the Big Bang event was only 400 million years ago, only the latest international team of scientists. This galaxy, led by Dr. Agos Bogdan from the Center for Astrophysics at Harvard University and the Smithsonian Institution (CfA Harvard & Smithsonian), made the first discovery of this type of galaxy. While exploring ancient quasars using the James Webb Space Telescope (JWST) and the Chandra X-ray Telescope (CXO), Getty Images Quasars are supermassive black holes. A gigantic being awake and absorbing large amounts of matter. It caused a surrounding bright light that was brighter than all the stars in that galaxy combined. This phenomenon led researchers to discover the seed of an primordial black hole in a galaxy called UHZ1 compared the growth rate of the quasar-centered supermassive black hole in UHZ1 with the expected growth rate of a rapidly growing primordial supermassive black hole. The team found that the black hole at the center of the quasar in UHZ1 accreted mass at a rate comparable to that of theoretical black hole seeds. This means it can grow to 10,000 solar masses. Over a period of hundreds of millions of years. The discovery of a galaxy that might be classified as the first OBG type galaxy is evidence of the existence of a seed of a black hole. This seed can grow into a giant supermassive black hole in a very short period of time. from the sudden collapse of matter in primordial space,” the team outlines how heavy seeds generally accelerate the growth of black holes. Growth of supermassive black holes in modern times Such as the Sagittarius Estar (SgrA*) black hole at the center of the Milky Way Galaxy, or the black hole M87 that we were able to image several years ago. It is not surprising that astronomers are puzzled by the fact that these supermassive black holes have a long accretion period, gradually growing to massive sizes over billions of years. It may ingest huge amounts of dust and gas. Or it might merge with another black hole. Until having a mass greater than billions of times the sun, it’s not difficult, however. To provide an explanation for the growth of primordial supermassive black holes. which can rapidly expand to a billion times the mass of the Sun Within less than 500 million years, it is extremely difficult to do, says Dr. Jon Reagan, a researcher at Maynooth University in the Republic of Ireland. As a metaphor to a Space.com reporter, “This is like walking down a street. and accidentally met a pair of young parents What is surprising is that They have toddlers who are regarding the same height as their parents. “What makes a baby grow up so fast? This question arises in a similar way to primordial giant black holes. which was born in a universe that is not very ancient It is expected that ancient black holes rapidly accumulated mass. Because growing up from The so-called “black hole seed”, or a smaller, pre-accumulated black hole, has two approaches to this hypothesis. Some believe that primordial supermassive black holes might grow from “Lightweight seeds” or microscopic black holes with masses ranging from 10-100 times that of the Sun. These seed black holes are formed by the collapse of the universe’s earliest stars. Another hypothesis believes that The seed of a supermassive black hole must be exceptionally heavy. It must have an initial mass of at least 100,000 times the mass of the Sun. which black holes are seeds of these heavy types Caused by direct collapse black holes (DCBH) of dust and gas in primordial space. Compare to see that Gigantic supermassive black holes that grow rapidly It’s like a toddler who can grow as big as his parents. Because just at birth, he is already many times taller than his age when considering the assumptions in the above two ways. There is only the idea of a heavy black hole seed. that can give birth to OBG galaxies in the primordial era Therefore, the discovery of the UHZ1 galaxy in line with the above hypothesis It is the first concrete evidence to confirm the validity of this idea. The research team noted that further validation of the data is still needed. To ensure that the age-old supermassive black hole There is a connection with supermassive black holes that are the seeds of real primordial times.
