A hidden black hole may be present in the large Magalanic cloud (LMC), a satellite of Milky Way. Evidence has been revealed through the discovery of hypervalocity stars on the edge of Milky Way, which appears to be inspired by a still–supermasive Black Hole within the LMC. Moving at an extraordinary speed, these fugitive stars were tracked using data of Gaia satellite of the European Space Agency. Conclusions show that while some of these stars were intensified by Milky Way’s own black hole, Dhanu A. (SGR A), Pointing to the presence of a large -scale gravitational force in that area, a significant number is removed from the LMC.
Evidence from Hyperwellosity Stars
according to a Study Approved for publication in the astrophysical journal, researchers analyzed 21 hypervalocity stars that are definitely for exiting Milky Way. Finding their origin, the team determined that about half of these stars were swept away from the core of Milky Way, but the remaining stars followed a trajectory associated with LMC. This considered scientists that a supermasive Black Hole within LMC could have played a role in intensifying them.
Jessie Han, Astrophysicist Center for Astrophysics | Harvard and Smithsonian (CFA) told Space.com that the possibility of another supermasive black hole in close proximity to Milky Way is striking. He said that black hole is often difficult to find out, which makes this discovery particularly important.
Potential mass and implication
The mass of this hidden black hole estimates about 600,000 times the Sun, based on the number and speed of stars extracted from LMC. Although smaller than Dhanu A*, which is 4.3 million times than the Sun’s mass, it fits within the required range for supermasive black holes.
Scott Luchi, a researcher at CFA, said the findings show that the Milky Way may not be the only galaxy to get the surrounding stars out due to the gravitational effect of a supermasive black hole. The findings of the study align with previous principles that predict the presence of hypervellosity stars as an unseen black hole in LMC.
