A team of researchers from the International Center for Relativistic Astrophysics has found evidence suggesting that Sagittarius A * is not a massive black hole but rather a mass of dark matter.

The study, published in the journal Monthly Notices of the Royal Astronomical Society: Letters, takes up the evidence that scientists have gathered to explain that the dark mass at the center of the galaxy, which the scientific community agrees to describe as a supermassive black hole (4 million times the mass of the Sun), would in fact be a core of dark matter.

Sagittarius A * still remains an enigma, as sciencealert points out. Never having been observed, astronomers have deduced its existence as well as its nature (black hole) according to the stars that revolve around and their behavior under the gravitational effect expected from such a monster.

However, theResearchers suggest that another type of mass could produce the same reactions and could even allow explain some anomalies that have been observed.

In fact, in 2014, a gas cloud (named G2) was moving to Sagittarius A * and should have been destroyed and “sucked” by the black hole. Yet it went from being a normal, compact state to something long and stretched, before becoming a compact object again. Finally, it is escaped unscathed and simply continued on his way through the galaxy.

A more than strange behavior if we start from the assumption that Sagittarius A * is a black hole, according to a team of astrophysicists led by Eduar Antonio Becerra-Vergara of the International Center for Relativistic Astrophysics.

With this anomaly in mind, the researchers carried out a computer simulation by replacing the black hole with a core of dark matter. According to their calculations, the Milky Way could function in much the same way as with a black hole. Nearby stars would behave in the same way, would have the same rotation curve and a gas cloud would not be sucked into it… To be continued!
