Valery LEBOVKA, “FACTS”
Security of mankind in the future depends on its ability to reveal the secrets of the world existing around us and use them for the benefit of themselves. One of these mysteries, along with the energy of black holes — the principle of the formation of galaxies in the Universe.
And in this regard may made the first significant discovery: a team of astrophysicists headed by Lina Necib of Caltech announced the discovery of a stellar stream that may serve as evidence that the disk of the milky way takes in the dwarf galaxy, being in constant development.
Star cluster was named NYX after the Greek goddess, who in mythology represents the personification of darkness. The discovery was made in an unusual way that reflects the diversity of astronomy and astrophysics.
Opening Nutty included the unification of these two major astrophysical projects and their analysis using the methods of deep learning.
“Galaxies grow by latching onto other galaxies. We assumed that the milky Way was a quiet merger history <…> Now, having access to a multitude of small structures, we understand that the history of the milky Way is not so peaceful as it seemed. Very useful to have all these tools, data and simulations. They must all be used simultaneously to solve this problem. We are in the initial stages, to really understand the formation of the milky Way, “notes Necib.
The team has developed a method to track the movements of every star in the virtual galaxies and labeling stars as the born in the host galaxy, and accretion as products of mergers of galaxies. The stars of these two types have different signatures, although the distinction is often elusive.
Necib and her team plan to continue the study of the flow NYX using ground-based telescopes. This will give information about the chemical composition of the stream and other details that will help them to date the arrival of Nucky in the milky Way and possibly give clues about how come the Homoof K. the Next data release Gaia in 2021 will contain additional information about 100 million stars in the catalog, making probable new open clusters.
Earlier, the “FACTS” wrote that last year NASA released a new photo taken by the Hubble telescope in deep space — the lens came spiral galaxy NGC 4380, unusual form which provoked the “other Association”. Fortunately, the “assumptions” are not met
