Scientists believe that dark matter and dark energy together make up about 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is a “normal” object. stars, planets, and living creatures. But for decades nearly half of this case has not been discovered either.
Now, using a new technique, a team in which the Instituto de Astrofisica de Canarias (IAC) has participated, has shown that this “missing” baryonic substance has been found filling the space between the galleries as hot, low-density gas. The same invention also provides a new tool that shows that the gravitational pull of galaxies is consistent with the theory of Universality. This research is published in three articles in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).
In designing this new method they have analyzed the changes in the electromagnetic spectrum, its movement to red, caused by reddening of light from the galaxies while they are distance away from us. In the Universe, the moving away sources show a redder spectrum, and those that come to us show a bluer spectrum.
This influence provided essential data for the development of modern cosmology. Almost a century ago, Edwin Hubble discovered that larger galaxies orbits are farther away from us, and this was the first evidence that led to the Big Bang model of the universe. Since then these red movements have been used to find the distances to the galleries and to construct three-dimensional maps of their distribution in the Universe.
In the work we report here a new method has been developed, which examines the reflex statistics of galaxies, without converting them to distances. In their first article, the team demonstrates that these maps are sensitive to the distraction between galaxies on cosmological blades. In a second article, the same team compares the maps with observations of microwave cosmic background ,, and they allow, for the first time, a complete account of the baryonic case during 90% of the life of the Universe.
“Most of this ‘normal’ case is invisible to us because it is not hot enough to emit energy. However, by using maps of gallery reflexes we can find that all this matter fills the space between them “, explained Jonas Chaves -Montero, a researcher at the Donostia International Physics Center (DIPC) and the first author of this article.
Finally, as found in a third article, the researchers have also used gallery reconstruction maps to study the nature of gravity. “Compared to previous approaches, our new method is not based on any reversal of remote regression, and is again shown to be robust again with sound and data inconsistencies. Thanks to that it allows us to conclude with great accuracy, that the ideas are consistent with Einstein’s theory of globalization “, notes Carlos Hernandez-Monteagudo, an IAC researcher who is the first author of this third article.
These studies were conducted by researchers Carlos Hernandez-Monteagudo, Jonas Chaves-Montero, Raul Angulo and Giovanni Arico, who designed the research during their time at the Aragon Center for Cosmic Physics Studies (CEFCA), even though they now work at other Spanish research centers, such as the Instituto de Astrofisica de Canarias, and the Donostia International Physics Center. One of the articles also featured a collaboration with JD Emberson, a Canadian researcher at Argonne National Laboratory, Illinois, USA.

A brighter future for wavelength astronomy
Potsdam, Germany (SPX) Mar 18, 2021
Future gravitational wave detectors use laser light with an even higher power than in conventional instruments. Researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI), Zentrum Hannover eV (LZH) Laser, and the University of Leibniz Hannover have now developed a new laser system for this purpose. They combined the unique light designed from two high-power lasers so that it meets the requirements for use in gravitational wave detectors. In … read more
