Astronomers suspect dozens of “ghost galaxies”

Lambda Cold Dark Matter (LCDM) indicates that most galaxies are low -block dwarfs, many of which are larger galaxies like the Milky Way. On a wider scale, the LCDM screen is the best understanding of how the universe works. But there is a problem. According to the theory, the milk method should have had more galaxies than the satellite than scientists noticed with telescopes and expected with computer simulation.

By combining the simulation with highly accurate computers so far with new sporty modeling, international scientists at Durham University in the United Kingdom indicate that there may be up to 100 unlimited galaxy before revolving around the Milky Way, and effectively follow our “missing” comrades in the galaxy. If future telescopes discover these galaxies directly, this will enhance the reliability of the LCDM theory, the most widely accepted standard of cosmology.

“If the highly dimmed satellite residents we expect with new data are discovered, this will be a remarkable success of the LCDM theory to form the galaxy,” said Carlos Frenk, a cosmologist from Durham University, at a university. statement. “Using physics laws, solving them using a large group of supercar computers and sporty modeling, we can make precise predictions that astronomers, who are equipped with strong, strong telescopes, can test them. Not getting much better than this.”

According to LCDM theory, 5 % of the universe consists of atoms, 25 % of the cold dark matter (CDM), and 70 % of the dark energy. Moreover, galaxies are born within groups of dark matter called halos. Before this new approach, the researchers claim that even the best cosmic simulations were not able to study very low galaxies or the developed of the dark matter over billions of years. The simulation mainly lost Halo “orphan” galaxies.

According to the continuous research presented at the National Society of National Astronomy of the Royal Society earlier this month, the technology of Frenk and its colleagues indicates that there are faded auras for dark materials that may host orphan satellite galaxies. They estimated the abundance, distribution and characteristics of these “ghosts” galaxies (as they are also called at the University of Durham press releaseHe suggested that the danger of the Milky Way may fully strip them of Halos, the aforementioned dark matter as well as the stellar mass.

“We know that the Milky Way has about 60 galaxies of the accompanying satellite, but we believe that there should be dozens of these dim wagles that revolve around the Milky Way at close distances,” said Isabelle Santos at Durham University. “Occupational astronomers use our predictions as a standard to compare the new data they get. One day we may be able to see these” missing “galaxies, which will be very exciting and we can tell us more about how the universe has become as we see today.

While the universe continues to hide endless secrets, it seems that we are sometimes on the right track.
