A star that was thrown through our galaxy at high speed probably is pushed out of her birth galaxy by some black hole that has never been seen before in our galaxy.

Keck telescope researchers believe that star PG 1610 + 062 was thrown through a galaxy from a black medium-sized hole (MMBH).

Data from the Keck Observatory revealed that PG1610 + 062 is, in fact, a surprisingly young, massive star that is ten times more massive, ejected from the Galactic Disk at almost the speed of escape from the Milky Way.

Researchers now believe that there is only one probable culprit – a black hole with an average mass.

Similar objects are thought to exist in young star clusters in the spiral arms of the Milky Way, but no one has yet been discovered.

"Now, PG1610 + 062 can provide evidence that MMBHs can indeed exist in our galaxy. says lead author Andreas Irgang of Friedrich-Alexander University in Erlangen-Nuremberg, Germany.

The race is actually to find them. "

The team needed spectral data for the star, but its distance and position of the sky made WM Keck's Echellette Spectrograph and Imager (ESI) the only tool for the job.

In the northern hemisphere only the combination of Keck Observatory and ESI gave us Keck's collection area allowed us to collect enough photons for our subject and ESI has exactly the right resolution that is high enough to allow for all spectral characteristics,
