Are dark matter clumps breaking holes in the Milky Way? – RT World News



In an astrophysical model that explains a mysterious disorder in the galaxy, a "dense sphere" of dark matter may have been plowed through the Milky Way, which is a million times larger than the Sun.

The theory of galactic hit-and-run "explains, according to Ana Bonaca, a Harvard-Smithsonian Center colleague, the jagged gap discovered in GD-1, the galaxy's longest stellar stream for astrophysics, who presented their theory last month in the American Physical Society. Instead of the single smooth-edged gap one would expect at the origin of the star stream, GD-1 has a second gap with a " Spur " of drooping stars, as if they were gravity.

why a gigantic blob of darker Matter? " We can not assign [the impactor] to any luminous object that we have observed ," explains Bonaca, and " it is much more massive than a star … a million times the mass of the sun . "That does not exclude the possibility -" it could be that it is a luminous object that has disappeared somewhere and is hiding somewhere in the galaxy "- but it would be difficult to hide something 30 up to 65 light-years across.

So without a visible culprit on which the celestial fender could be moored, and without telltale signs of a black hole like the massive one believed to lie in the center of the milk Bonaca, by the way, believes that a large "lump [19659007] "Dark matter could be responsible for the crack in GD-1. Despite the researchers' frustrating inability to "prove the existence of dark matter," most agree that it far surpasses dark matter, holds galaxies together, and gathers in their centers.

Bonaca was able to pinpoint the strangeness of outer space by examining a galactic map from the Gaia mission, the most complete representation of the Milky Way, and their cross-reference to the observation through a multi-specular telescope that is capable of To recognize the direction in which the stars move. This method produced the most accurate image of GD-1 and hopes to map more of the Milky Way, in the hope that other areas may emerge in which similar dark monsters may have settled – finally to the position of this dark matter determine. " Lump " in the whole galaxy.
