A supermassive black hole was discovered near the Milky Way galaxy

Astronomers at the University of Texas at Austin have recently observed giant black holes very close to our solar system; The black hole at the center of one of the countless tiny galaxies immersed in the Milky Way galaxy.

The weird thing about this black hole is its mass ratio. Researchers calculate the gravitational force that Leo I Looking at the stars around it, they realized that this black hole has an extremely large mass due to its size.

This research team is from the spectrograph VIRUS-W And telescopes Harlen Smith At the observatory McDonald’s The state of Texas has been instrumental in discovering this. The spectrograph is very accurate in calculating the velocity of stars in distant galaxies.

Carl Gabhart, One of the astronomers present in the study, says about this:

Our models and calculations explicitly state that there must be a black hole at the center of the galaxy, and that large amounts of dark matter are not required.

The stronger the gravity, the faster the stars move. The faster motion of the stars indicates the greater accumulation of dark matter, the mysterious substance that makes up much of the mass of the universe, in that region.

He adds:

We see a small galaxy falling toward the center of the Milky Way, and the black hole at its center is almost the same mass as the black hole at the center of the Milky Way. Its mass ratio is surprisingly large; But the center of the Milky Way galaxy dominates this interaction.

The models used in this study deal a major blow to existing theories about how galaxies evolve; Because so far no explanation has been given for spherical microgalaxies. The discovery prompts astronomers to rethink the reasons they give for how matter is distributed within galaxies.

Professor Gabhart In this regard, he says:

It may be due to too much crime Leo I We can explain how black holes grow in large galaxies.

The findings are published in The Astrophysical Journal.
