Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of supermassive black holes and will eventually merge into one giant black hole. Located in the ...

A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team finds that rather than the conventional formation scenarios involving “normal” matter, supermassive black holes could instead form directly from dark matter in high-density regions in the centers of galaxies. The result has key ...
An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers, used 52 stations with LOFAR antennas spread ...
A recent study suggests the possible existence of “stupendously large black holes” or SLABS, even larger than the supermassive black holes already observed in the centers of galaxies. The research, led by Queen Mary Emeritus Professor Bernard Carr in the School of Physics and Astronomy, together with F. Kühnel (Münich) and L. Visinelli (Frascati), investigated ...
With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand ...
When you look up at the night sky at the galaxies, how do you know whether the specks of light that you see are bright and far away, or relatively faint and close by? One way to find out is to compare how much light the object actually emits to how bright it appears. The ...
The origin of high-energy cosmic neutrinos observed by the IceCube Neutrino Observatory, whose detector is buried deep in the Antarctic ice, is an enigma that has perplexed physicists and astronomers. A new model could help explain the unexpectedly large flux of some of these neutrinos inferred by recent neutrino and gamma-ray data. A paper by Penn ...
Astronomers from UCLA’s Galactic Center Orbits Initiative have discovered a new class of bizarre objects at the center of our galaxy, not far from the supermassive black hole called Sagittarius A*. They published their research in the journal Nature. “These objects look like gas and behave like stars,” said co-author Andrea Ghez, UCLA’s Lauren B. ...
A gigantic, balloon-like structure has been hiding in plain sight, right in the center of our own galaxy. An international team of astronomers, including Northwestern’s Farhad Yusef-Zadeh, discovered the structure, which is one of the largest ever observed in the center of the Milky Way. The newly spotted pair of radio-emitting bubbles reach hundreds of ...
