Available Expert - A truly black hole

Thursday, May 7, 2020

 Queen’s University black hole expert  and PhD candidate Nikhil Arora (Astrophysics) is available to comment on a discovery astronomers have discovered just 1000 light years from earth. It was discovered in the system called HR 6819, in the constellation Telescopium, and recently published in the journal Astronomy and Astrophysics.  It is based on data collected using telescopes at ESO’s La Silla Observatory in Chile.

“There are a few interesting aspects about the system HR 6819. The remarkable thing about the black hole in HR 6819 is that it is not building up any gas and therefore not emitting light. It is a truly dark black hole” says Arora.

Most previously seen black holes are observed because we can see significant X-ray radiation. The observation of this black hole marks the beginning of a new way to detect these dark black holes. Currently, only about 30 stellar black holes are known to be in our galaxy.

With this new technique, Arora says we can start to see a large number of black holes living in our galaxy.
