Does a black hole fire up cold heart of the Phoenix?

Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster, located 5.9 billion light-years away in the constellation Phoenix. This is an important ...

Slippery superfluids push jets to breaking point

A unique type of helium that can flow without being affected by friction has helped a KAUST team better understand the transformation of rapidly moving liquids into tiny droplets.

A galaxy's stop-and-start young radio jets

In this image, made with the National Science Foundation's Very Long Baseline Array (VLBA), young, radio-emitting jets of material emerge from the core of an elliptical galaxy some 500 million light-years from Earth. After ...

Spinning black hole powers jet by magnetic flux

Black holes are at the center of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light. But they can also emit matter in the form of plasma ...

Very high energy gamma-ray emission from a radio galaxy

Giant elliptical galaxies, the oldest known large galactic structures in the universe, have no spiral arms and little or no current star formation activity, but their central supermassive black holes are often active galactic ...

Strange gamma-ray heartbeat puzzles scientists

Scientists have detected a mysterious gamma-ray heartbeat coming from a cosmic gas cloud. The inconspicuous cloud in the constellation Aquila is beating with the rhythm of a neighboring precessing black hole, indicating a ...

New precision search for dark matter from ATLAS Experiment

The nature of dark matter remains one of the great unsolved puzzles of fundamental physics. Unexplained by the Standard Model, dark matter has led scientists to probe new physics models to understand its existence. Many such ...

Cosmic quasars embrace 1970s fashion trend

Researchers from Russia, Germany, Finland and the U.S. have studied more than 300 quasars—spinning black holes that produce beams of plasma. The team has found that the shape of these so-called astrophysical jets changes ...
