Dark matter makes up more than a quarter of the universe, scientists have realized, but they have not yet learned how to see it directly. (Strange materials do not emit, absorb, or reflect light, hence the name.) So they turn to the effects they can see, such as a clump of dark matter There is a space around it, Our view of objects on the other side. But according to a new study, some small groups are distorting much more than space, which scientists expected.
“A feature of the real universe that we are not only capturing in our current theoretical model,” Priyamvada Natarajan, a theoretical astrophysicist at Yale University and a Cauthor on new research, Said in a statement. “This may indicate a difference in our current understanding of the nature of dark matter and its properties, as these exquisite figures have allowed us to examine the broadest distribution of dark matter at the smallest scale.”

The scientists behind the new research wanted to investigate how existing theoretical models of round matter could stack up with rounding observations. So they turned Galaxy cluster, Which hide a large amount of dark matter.
Massimo Menegaty, a cosmologist and new author of the National Institute of Astrophysics in Italy, said, “Computer simulations of the universe are ideal laboratories to understand what computer simulations of the universe can reliably predict about dark matter and shiny objects. ” Research, the statement said.
Researchers observe three different galaxy clusters collected by two devices Hubble Space Telescope And this Very large telescope in Chile. The scientists mapped the dark matter within the bunches, observing how the material was fighting the light.
Amidst the massive distortions astronomers expected to find, they also observed small areas of warfare, which they suspect marked the locations of individual, small cluster galaxies that concealed concentrations. Dark matter.
But when researchers combined their map of Dark Matter with the predictions of the Dark Matter model seen in cluster galaxies, there were no two landscape lines. This means that scientists still have not understood the puzzle of how Dark Matter behaves.
Research is described in a paper Published today (11 September) in the journal Science.
