This illustration shows how binary stars interact with a supermassive black hole to create a population of hypervelocity stars that end up being gravitationally kicked so strongly that they are expelled from their local galaxy. This process must be at stake in any galaxy with a supermassive black hole, including the nearby Magellanic (LMC) cloud, which is shown to the right. As a result, many hyper -reveal stars that originate in the LMC should now exist within the Milky Way. (Credit: CFA/Melissa Weiss)
Only 165,000 light years away, it is suspected that the great cloud Magellanic houses a supermassive black hole. Finally, evidence has come.
Throughout the universe, practically all galaxies house a supermassive black hole.
Messier 87, better known as the supermassive galaxy whose black hole was photographed by Event Horizon Telescope, has its relativistic aircraft and shock waves created by its material images in the infrared by Spitzer, in the middle of the mass of bright stars (in blue). Messier 87 is the most massive (and most bright second) galaxy within the entire Virgo galaxies group, and is the central black hole that generates these relativistic planes.

Whenever they actively feed, they throw energy radiation.
This field of vision, corresponding to approximately 1/15 of a square grade, shows the Candra Deep Field South and represents a total of around 2000 hours of total observation time. Approximately 5000 Supermasive black holes were detected, with a small amount of hot gas around a few objects that appear as diffuse and extended, instead of scores, Fuentes.

This activity also abounds in the center of the Milky Way.
The supermassive black hole in the center of our galaxy, Sagittarius A*, emits radiographs due to several physical processes. The flares that we see on the radiography indicate that the matter flows unequally and not continuously in the black hole, which leads to the flares that we observe over time. In X -rays, there is no visible event horizon in these resolutions; “Light” is purely like an album. (Credit: NASA/CXC/AMHERST COLLEGE/D.HAGGARD et al.)
However, only 27,000 light years of light, our black hole is more directly observable.
This time period of 20 years of stars near the center of our galaxy comes from ESO, published in 2018. Observe how the resolution and sensitivity of the characteristics are exacerbated and improve towards the end, all orbiting the central supermassive black hole of our galaxy (invisible). It is practically believed that every great galaxy, even in the early stages, houses a supermassive black hole, but only the one in the center of the Milky Way is close enough to see the movements of the individual stars around it and, therefore, determine precisely the mass of the black hole. Similar techniques could reveal black dough holes in globular groups, although during longer time scales. (Credit: ESO/MPE)
You can track individual star orbits, revealing its mass.
Size comparison of the two black holes images of the collaboration of the telescope of the event horizon (EHT): M87*, in the heart of the Galaxy Messier 87, and Sagittarius A*(SGR A*), in the center of the Lilky road. Although Messier 87’s black hole is easier to obtain images due to slow time variation, in addition to being intrinsically approximately 1500 times larger, the one that around the center of the Milky Way is the largest as seen from Earth in terms of angular size. Artificial neuronal networks were vital to analyze and process the data used to recover these images. (Credit: EHT Collaboration (Recognition: Lia Medeiros, XKCD))
When multiple masses interact under their own mutual gravitation, the smallest masses tend to obtain larger kicks, where they hit higher orbits or completely expel, which often results in hyper -velocity objects. Meanwhile, the remaining objects end even rather, gravitationally speaking. In the distant future, the stellar remains of our galaxy will be expelled almost all in this way, with only a few attracted in the central and supermassive black hole in its place.

However, supermassive black holes also cause an indirect and indirect gravitational effect: create Fugitive stars and hypervelocity.
The Star Mira, as shown here, according to the Galex Observatory in the ultraviolet, accelerates through the interstellar medium at speeds much larger than normal: at approximately 130 km/s, which is approximately ten times faster than the typical speeds, but is still below the exhaust speed of the Milky road. Mira’s trajectory does not go back to the galactic center, which indicates that a minor gravitational interaction gave him his high speed kick. However, many stars that are not looking have achieved sufficient speeds to gravitationally relieve them of our local galaxy, with a significant fraction of which they can be traced to the galactic center.

The hypervelocity stars were First predicted in 1988: Of the binary stars systems that interact with a supermassive black hole.
