Minor merger kicks supermassive black hole into high gear

The galaxy Messier 77 (M77) is famous for its super-active nucleus that releases enormous energy across the electromagnetic spectrum, ranging from x-ray to radio wavelengths. Yet, despite its highly active core, the galaxy ...

Rapid imaging of granular matter

Granular systems such as gravel or powders can be found everywhere, but studying them is not easy. Researchers at ETH Zurich have now developed a method by which pictures of the inside of granular systems can be taken ten ...

SOFIA finds cool dust around energetic active black holes

Researchers at the University of Texas San Antonio using observations from NASA's Stratospheric Observatory for Infrared Astronomy, SOFIA, found that the dust surrounding active, ravenous black holes is much more compact ...

Physicists use numerical 'tweezers' to study nuclear interactions

Researchers from North Carolina State University and the Ruhr-Universität Bochum have developed numerical "tweezers" that can pin a nucleus in place, enabling them to study how interactions between protons and neutrons produce ...

New CERN results show novel phenomena in proton collisions

In a paper published today in Nature Physics , the ALICE collaboration reports that proton collisions sometimes present similar patterns to those observed in the collisions of heavy nuclei. This behaviour was spotted through ...

Black holes hide in our cosmic backyard

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes. But they give themselves away when material they feed on emits high-energy X-rays that NASA's NuSTAR (Nuclear Spectroscopic ...
