Detecting a series of perfection in the universe
The Swiss team discovered 19 quasars that have surround halo, contrary to predictions in previous models.
The team from the Swiss Federal Institute of Technology uses the MUSE spectrophotometer of the Very Large Telescope (VLT) to discover 19 quasars that have a halo around the universe, according to UPI.
Quasars are black holes emitting many powerful radioactive explosions from their accretion disks. The accretion disk is a dense circle of gas and debris absorbed by the gravitational pull of the black hole. When the materials are concentrated, it emits a large amount of energy. Quasars are the brightest objects in the universe.
Previous studies have shown that only 10% of total quasars have surrounding halos. In a study published in the Astrophysical magazine on September 26, the Swiss team published a 19-crystal image with a halo. These halos are about 300,000 light-years away from the center of the black hole.

In particular, they discovered that the gas constitutes 19 halos with a temperature of only 10,000 degrees Celsius, which is "much colder" than estimated millions of degrees Celsius in previous research models. This new finding is likely to cause astronomers to rethink the model they created to study quasars.
The team used the VLT telescope and its devices at the Paranal observatory in Chile to produce this impressive result.
"It is still very early to conclude that this result is due to our new observation technique or what the quintessential experiments have. Therefore, there are still many issues to study. We are just in the early stages of a new discovery era, " Elena Borisovam, from the Swiss Federal Institute of Technology, the lead author of the study, said.
The team hopes to find the answer with the tool they used.
"We have exploited the special ability of MUSE in this study. It will pave the way for future surveys. Along with new generation theory and numerical models, this method will provide more information about the formation of the cosmic structure and the development of the galaxy, " co-author Sebastiano Cantalupo said.
