“The new study has been published today in Monthly Notices of the Royal Astronomical Society (MNRAS).

It challenges the leading theory that Sagittarius A* (Sgr A*), a proposed black hole at the heart of our galaxy, is responsible for the observed orbits of a group of stars, known as the S-stars, which whip around at tremendous speeds of up to a few thousand kilometres per second.

The international team of researchers have instead put forward an alternative idea – that a specific type of dark matter made up of fermions, or light subatomic particles, can create a unique cosmic structure that also fits with what we know about the Milky Way's core.”

Interesting article and proposal will be interesting what future findings on this will present itself for those wanting to look through the arxiv article itself
