The Gaia-Eso Study has Revealed New Information about Our Galaxy

After the Big Bang, only helium and hydrogen existed thereafter, and the level of "contaminated metal" increased with time. In other words, the older the stars are, the less polluting metals in the cosmetics will be. One such "contaminated metal" is magnesium. And it was found in a huge star, "fast and young" (Cambridge University, 2014). Therefore, in this study using the VLT telescope in Paranar, Chile, we gathered information on the age and position of the star to understand whether the Milky Way was created from the inside.

The Herschel Space Observatory is a space telescope that studies the universe through spectra in the far infrared and submillimeter bands. It reveals new information about the earliest and furthest stars and galaxies, as well as information closer to home than in space and time. It also takes a unique perspective on our own solar system. The wavelengths of far-infrared and submillimeter waves observed by Herschel far exceed the familiar rainbow color that can be perceived by human eyes. But for scientists this is a very important part as it is the frequency range of most of the radiation in the universe.

In addition to revealing the dynamics of the stars of our Milky Way, this study also influenced emerging (GW) research areas. Basically, by knowing how many black holes are in the center of a galaxy (which blend periodically with each other), astronomers can better predict the number of gravity wave events associated with them I will. In this way astronomers can create predictive models of when and how GW events will occur and identify the possible roles they will play in the evolution of galaxies. Using next generation equipment such as the James Webb Space Telescope (JWST) and the European Space Agency's High Energy Astrophysics (ATHENA), astronomers exactly how many black holes are near the center of the galaxy You can decide.

Research on the black hole at the Hubble Telescope Center confirmed our understanding of these central engines. And it is deeply hidden in the center of almost every galaxy. In front of the Hubble telescope, a black hole, and even a massive black hole was known, but the Space Telescope has a large number of massive black holes in order to show that each central galaxy cluster contains a super mass black hole centered on the bright galaxies I was able to measure the galaxy. Many dwarf galaxies lack these central black holes, but most galaxies contain millions to tens of times the galaxies of the sun. The results of the Hubble telescope also show that with the passage of time the central bulge of the stars in the galaxy and its accompanying black hole evolve together and the growth of the central bulge is related to the growth of the black hole I will.
