Hidden matter hidden in a cosmic web
Using a new statistical analysis of data from 30 years ago, experts have been able to find the matter that forms stars, planets and galaxies.
French astrophysicists at the University of Paris-Saclay announced the discovery of hidden matter in the Universe. Its volume is about 40 percent of the usual substance, writes Astronomy & Astrophysics.
It is believed that outer space is 60 percent of ordinary matter, and 40 percent of latent matter. It forms stars, planets and galaxies. However, it remains undetected, hidden in the form of hot gas, covered by a cosmic web.
And here the French scientists for the first time managed to discover the presumably the same hidden matter. They made this discovery using groundbreaking statistical analysis of data from 30 years ago.
The researchers conducted a statistical analysis of the distribution of matter in galactic filaments (filaments) – cosmic structures that connect clusters of galaxies and are filled with gas. The filaments are believed to contain almost all of the baryonic matter in the Universe as diffuse gas. But the signal it emits is so weak that in reality, half of the baryons of this composition remain undetected.
In a new study, astrophysicists compiled a statistical analysis that was able to demonstrate for the first time x-rays from hot baryons in filaments. They used the correlation between fiber position and radiation intensity to estimate the amount of material in the filament and measure the temperature of the gas.
The results of this study confirm earlier assumptions that hot gas in the cosmic web has a general effect on the overall cosmic microwave background.
Before that, we wrote that dark matter “gave a signal.” The experiment takes place in a special laboratory located deep underground.
As previously reported, scientists have confirmed a new theory of dark matter.
