Since Edwin Hubble in the 1930s identified that the galaxies were not randomly distributed, but have been assembled in groups, astronomers seek to know Super walls and galaxy walls.
Today it is known that you cannot understand the universe without knowing these huge structures, which not only affect the basic cosmic measurements, but also affect the behavior of matter and light.
Recently, an international team of physicists and astronomers, led by researchers at the Max Planck Institute of Physics in Munich, Germany, “History” When the largest known structure is found ever in the universe.
Call of QuipuIn honor of the Inca account made of colored ropes, this huge group of galaxies extends to about 1.3 billion light years (more than 400 megabyard).
This structure and another four were found by researchers It contains 45 % of galaxy groups, 30 % of galaxies, and 25 % of the issue and occupies a volume of 13 % of the monitored area.
How was this cosmic cosmic cousin discovered?
Under the physical leadership of MPE Hans Boehringer, the study was part of the large cosmic cosmic structures collection. He studied through their X -ray emissions, these groups contain thousands of Galaxies And a large amount of hot gas inside the crown.
In their research, the authors found Quipu and four other metal structures within a tape of 130 MPC (Megaparscs, equivalent to about 424 million light years) and 250 AD (about 815 million light years).
To get an idea about these extensions, just say that our galaxy, A milky wayAbout 100,000 light years in the diameter. PARSEC (PC), in turn, equivalent to 3.26 light years, or about 30.9 trillion kilometers.
The use of X -ray galaxy emissions is necessary to determine the mass of these superstructures, because electromagnetic radiation Oste The most dense areas of the basic cosmic material and cosmic network.
Regardless of the reasons for this, the authors say, “These large structures leave their mark in cosmic notes.” This is great in the background of the cosmic microwave (CMB), the remaining radiation of the big explosion.
Effects of metal structures such as Quipu on the monitoring of the universe
Lavo structures, such as Quipu, affect CMB because their intensity causes the so-called integrated Sachs-Wolfe effect, which are small differences that can be detected in the temperature in the fossil of fossil, the large explosion.
Lusory structures also affect the Hubble fix (the expansion rate), because It prints the strong gravity of galaxies. This can “tamper” measuring speeds above the expected flow.
In addition, the mass of these cosmic concentrations multiplies the light that passes through it, The impact of the gravitational lens. The result is distorted pictures of galaxies and other luminous sources.
Finally, Quipu and her sisters affect the way in which the material is organized in the universe, whether visible (baroni), made of stars or planets, gas and dark materials, which do not emit light but are gravitational.
In addition to describing the metal structures, the study also expects its end, saying that it is in the cosmic development in the future, is convicted of collapse in many distinct units, and thus “transit formations”.
The study concluded that “today, they are special material entities, with distinctive characteristics and special cosmic environments that deserve special attention.”
