Astronomers reject the connection of black holes and dark matter

UNITED STATES (VOP TODAY NEWS) – One of the models links dark matter with the gravity of imperceptible black holes for us, but observations of distant supernovae allow us to doubt this hypothesis.

Calculations show that the lion’s mass of the Universe falls on invisible dark matter , but its nature remains a mystery. Theoretical models sometimes give opposite descriptions: some say that dark matter consists of incredibly light and weakly interacting particles of axions; others associate it with massive objects of stellar and galactic scales, which consist of ordinary particles of baryonic matter, but escape from observations.

One of the main candidates for such a MASON (Massive Astrophysical Compact Halo Object, “Massive Astrophysical Compact Halo Object”) are primary black holes formed in the young and super dense Universe even before the appearance of stars. Massive and dense, in accordance with the General Theory of Relativity, these black holes should create deformations of space-time. And if the light from a distant and sufficiently powerful source passes in the vicinity of such a gravitational lens, it will be deformed and amplified.

Astrophysics from the University of California at Berkeley Zumalakaredzhi Miguel (Miguel Zumalacárregui) and Uros Selyakov (Uroš Seljak) examined how often gravitational lenses distort and amplify the light from distant supernovae to give an upper bound for the number of unseen us black holes and their possible contribution to the dark matter. Article scientists published in the journal Physical Review Letters .

The study of data on the 740 brightest supernovae showed that even if black holes do contribute to the phenomena that are associated with dark matter, it is no more than 40 percent. According to the authors, they already have in their hands and yet unpublished results of a more complete analysis, which covered more than 1,000 supernovae and makes it even lower this figure – up to a maximum of 23 percent.

“We are returning to the usual discussions. What is dark matter? It looks like we’ve got some good options, ” says Professor Urog Selyak. “This is a challenge for future generations.”
