Black holes are thought to be common in the universe, with a supermassive gobbler lurking at the core of galaxies such as our own Milky Way. But might they also be found roaming outside the galactic centers?
A new study estimates that approximately 300 black holes may lurk throughout the Milky Way, remnants of the building blocks that came together billions of years ago to form the galaxy. What is more, those black holes may retain properties that would allow astronomers to identify them, providing an archaeological record of the galaxy's formation.
Ryan O'Leary, a graduate student at the Harvard-Smithsonian Center for Astrophysics (CfA), and CfA professor Avi Loeb conducted the research, set to be published in the Monthly Notices of the Royal Astronomical Society.
