Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say.
Using NASAs Chandra X-ray Observatory and ESAs XMM-Newton satellite, scientists at Penn State University and the Massachusetts Institute of Technology found evidence of high-speed winds blowing away copious amounts of gas from the cores of two quasar galaxies, which are thought to be powered by black holes.
"The winds we measured imply that as much as a billion suns worth of material is blown away over the course of a quasars lifetime," said George Chartas of the Penn State Astronomy and Astrophysics Department, who led the observations. The winds might also regulate black hole growth and spur the creation of new stars, according to the science team, which includes Niel Brandt and Gordon Garmire of Penn State and Sarah Gallagher of MIT.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
