Исследование предлагает ядро из темной материи в центре Млечного Пути

"...something incredibly heavy is pulling the strings..."

"...swing around it at breakneck speeds..."

"...gas heats up and glows..."

"...even light itself seems to bend..."

"...treated this object as a settled case..."

"...may have been misidentifying the culprit..."

"...bottomless gravitational pit..."

"...exotic, ultra-dense form of dark matter..."

"...so compact that it behaves like a black hole without actually being one..."

"...change how scientists think about black holes..."

"...role dark matter plays in structuring entire galaxies..."

"...big cosmic disconnect..."

"...long-standing problem in galactic physics..."

"...motions demand something both massive and compact..."

"...galaxy behaves very differently..."

"...rotation decreases with distance in a way that resembles classical, Kepler-like motion..."

"...models are not naturally connected..."

"...horizon-less configurations..."

"...reproduce the relativistic effects measured for S2 orbit..."

"...part of a single continuous configuration..."

"...extended halo reproduces the latest GAIA-DR3 rotation curve..."

"...standard cold dark matter halos tend to spread out smoothly..."

"...do not easily reproduce the detailed shape of the Milky Way’s observed rotation curve..."

"...especially the Keplerian decline seen by Gaia..."

"...disconnect is what motivated the researchers to explore a different possibility..."

"...single dark solution..."

"...research team took a different approach..."

"...focusing on fermionic dark matter..."

"...particles that obey quantum rules preventing them from being squeezed indefinitely into the same space..."

"...dark matter particles are assumed to have a specific mass range..."

"...quantum effects to become important at galactic scales..."

"...enough of this matter accumulates..."

"...forms a stable, extremely dense central core surrounded by a more diffuse halo..."

"...single structure does two jobs at once..."

"...compact core can reproduce the observed orbits of S-stars and nearby dust-enshrouded objects known as G-sources..."

"...exerting nearly the same gravitational pull expected from a supermassive black hole..."

"...surrounding halo naturally explains the slowing of the Milky Way’s rotation at large distances..."

"...combined with the mass of ordinary matter in the galaxy’s disk and bulge..."

"...unlike standard dark matter models..."

"...fermionic halo becomes more compact at large radii..."

"...helps explain why Gaia sees a clear decline in orbital speeds..."

"...team also addressed a crucial observational test..."

"...not within this study alone..."

"...earlier, related work..."

"...researchers showed that when hot gas falls toward such a dense dark matter core..."

"...bending of light can produce a dark central region surrounded by a bright ring..."

"...shadow-like feature closely resembles the image of Sagittarius A* captured by the Event Horizon Telescope..."

"...even though the dark matter core has no event horizon..."

"...future of the Milky Way’s center..."

"...Milky Way’s center is indeed dominated by fermionic dark matter..."

"...galaxy’s central object and its dark matter halo are not separate components..."

"...not just replacing the black hole with a dark object..."

"...proposing that the supermassive central object and the galaxy’s dark matter halo are two manifestations of the same, continuous substance..."

"...Carlos Argüelles, one of the study authors and a scientist at the Institute of Astrophysics La Plata, said..."

"...offer one of the first unified explanations linking the extreme gravity near the galactic center with the large-scale structure of the galaxy..."

"...influence how astronomers interpret black hole candidates in other galaxies..."

"...guide future efforts to identify the true particle nature of dark matter..."

"...idea is not yet settled..."

"...current data..."

"...motions of stars near the galactic center can still be explained equally well by a black hole or by a dense dark matter core..."

"...two scenarios begin to differ only in subtle ways..."

"...key distinction is the presence of photon rings..."

"...specific light patterns expected around true black holes but absent in dark matter core models..."

"...future observations with instruments such as the GRAVITY interferometer on the Very Large Telescope and improved Event Horizon Telescope will be crucial..."

"...more accurate data, particularly from stars closer to Sgr A, is necessary to statistically distinguish between the models considered..."

"...study authors said..."

"...study has already shifted the debate..."

"...showing that even the best-known structure in our cosmic neighborhood may still be open to reinterpretation..."

"...study is published in the journal Monthly Notice of the Royal Astronomical Society..."
