The general case can only make up only 5 percent of the mass of the universe, but that does not mean that we know where it all is. In fact, for 20 years, astronomers are trying to figure out that there is not much as much as it should be.
Now an international team has put his head together to solve the missing barrier problem and found it floating in the middle of the stars.
Whatever material we can find in the universe, it is composed of baryonic particles. Stars, planets, nebulous, plasma, even black holes are also made of baryonic materials.
Nevertheless, according to the research team, only two-thirds of the case was attributed – apparently, a full third was left in the Land of Lost Sox.
Fabrizio Nicastro, an astronomer of the INAF, and Astronomy physicist of the Harvard-Smithsonian Center for Astrophysics said, “The disappearing baryons represent one of the biggest secrets in modern astrophysics.”
“We know that this matter should be there, we see it in the early universe, but then we can not catch it. Where did it go?”
According to the 2012 Census of the Unions, about 10 percent of the barriers can be found inside the galaxies, and 50 to 60 percent of galaxies between galaxies can be found in the clouds and areas of hot gas surrounding galaxies circumgalactic Medium.
It still leaves between 30 to 40 percent. It is a web of hot, spreading gas between galaxies, which is considered to be left after their formation.
Michael Schull of the University of Colorado Boulder said, “This is where nature has become very distorted.” “This intergalactic medium contains filaments of gas at temperatures ranging from a few thousand degrees to some million degrees.”
Because it has spread so much, it is difficult to see – practically invisible.
Until you backlight it, the same researchers did. He found a quasar called 1ES 1553, which was a very active black hole-galaxy in the original sky. The Universe is some of the brightest objects in the universe.
The use of this light can be used to lie between us and him – and in this case, it was a filament of WHIM.
A research team used XMM-Newton X-ray to inspect 1 ES 1553 of, in 2015-2017
Fabrizio said, “With the data, we were able to find the signature of oxygen in warm intergalactic gas between our and distant quasars, at two different places with vision and line.”
The WHIM generating gas is actually the ionized hydrogen, in which there is no electron to produce spectral facilities.
From here, Fabrizio and his team are planning to use other quarters to confirm their findings.
Another secret is how it was built in the first place. But we may have to wait for the powerful ETHANA Telescope of ESA’s planned ESA for the launch of 2028 for the answer.
Astronomist Jale Castro of the Netherlands Institute for Space Research said, “The discovery of the missing bayions with XMM-Newton is the first step to mark those conditions and structures completely, in which these barians are found.”
“For the next steps, we will need high sensitivity to Athena, in which the warmth is the main goal of the intergalactic medium to improve our understanding of the evolution of structures in the history of the universe.”
The research has been published in the journal Nature.
