In a binary black hole system, the directions of the spin angular momentum of each black hole (red cone arrows) and of the orbital angular momentum for the system (blue cone arrow) change, or precess, over time. Credit: Midori Kitagawa New research by an astrophysicist at The University o...

The team made the discovery while investigating the link between the cold gas around active black holes and how these are fuelled in the WISDOM sample of 35 nearby galaxies captured by the Atacama Large Millimeter/submillimeter Array (ALMA) of telescopes in Chile. Dr Ruffa added: “Our study s...
Astronomers have found a quasar 12 billion light years away hosting a supermassive black hole that gobbles up a sun-sized amount of mass every day
We report on the discovery by the Swift Gamma-Ray Burst Explorer of the black hole (BH) candidate Swift J1539.2-6227 and the subsequent course of an outburst beginning in 2008 November and lasting at least seven months. The source was discovered during normal observations with the Swift Burst...
Thompson and other astrophysicists had long suspected that black holes might come in sizes outside the known range, and LIGO's discovery proved that black holes could be larger. But there remained a window of size between the biggest neutron stars and the smallest black holes. ...
More massive than expected, the black holes collided three billion years ago and sent gravitational waves washing over Earth.
In gravitational terms, this means that the simulations produce new types of waves. “If you dig deeper under the large waves, you will find an additional new wave with a unique frequency,” Mitman says. In the big picture, these new simulations will help researchers to better characterize fu...
as well as a set of high-ranking, large burials of the early and middle phases of the Songze Culture for the first time in the circum-Lake Tai 环太湖 area. All of the small burials of the Songze Culture were found in Zone I of the site, all of the house foundations were found in...
However, it has been pointed out that the large variety of AFM states should allow for a wider range of AFM DW configurations compared to ferromagnets12. It is expected, that the details of the spin texture within an AFM DW play a crucial role for its properties regarding, for instance, ...
