Scientists have managed to determine one of the biggest mysteries in recent astrophysics – the formation of quasars in the early universe. These cosmic entities were first observed in 2003, and soon after, more than 200 quasars were identified by supermassive black holes. These 200 quasars formed within the first billion years after the creation of the universe. Scientists have never been able to conclusively determine how these quasars formed so quickly in the universe. Now, a team of researchers has discovered that these elemental quasars formed naturally under the chaotic conditions of the rare gas reservoirs of the early universe.
“First Supermassive black holes Cold dark matter was a natural consequence of structure formation in cosmology—the children of the cosmic web.” Told Dr. Daniel Whelan from the University of Portsmouth.
Dr. Whelan led the team of researchers behind the study that determined its origin Kaiser, study Posted on 6 July in Nature.
The researchers used a super computer Models to run simulations of where these quasars might form. Scientists found that when supermassive black holes form, quasars are formed, whose mass is at least 100,000 times that of ours. Sunday, in those regions of space where cold powerful currents of gases were found in strong concentration. These gaseous currents are found in a region of about a dozen or more space Across 1 billion light years.
“As a result, the only elemental cloud that can form a quasar just after cosmic dawn—when the first Stars In Universe Formed – also easily made their own mass seeds. This simple, beautiful result explains not only the origins of the first quasars but their demographics – their numbers in early times,” said Dr. Whelan.
Quasars are some of the most powerful and energetic objects in the universe. found in the far center galaxies, quasars are powered by supermassive black holes whose masses range from millions to tens of billions of solar masses. These black holes get deposited in the surrounding matter which gets heated due to friction and pressure as they fall towards the black hole. The heat and electromagnetic energy created in this way is released by the quasar as electromagnetic energy.
