Physicists Devise New Way to Listen for ‘Hairy’ Black Holes
When two black holes merge, the resulting object rings like a struck bell, radiating gravitational waves that fade in a distinctive pattern called ringdown. The post Physicists Devise New Way to Listen for ‘Hairy’ Black Holes appeared first on Sci.News: Breaking Science News.
The resuscitation of a black hole could reveal more than just mass and rotation. A new calculation method combines changes in frequency and attenuation with the properties of additional matter near the black hole. However, the authors stress that their formulas only apply in the econal range and that real gravitational wave signals have to be calculated even more precisely. Nagoya (Japan). After the fusion of two black holes, the newly created o…
Japanese scientists have shown how astronomers can open "haired" black holes using gravitational waves. A new mystery parameter, besides back and mass, can indicate the presence of invisible matter around the black hole.
Future observations of black holes by LISA could reveal the existence of unknown particles much lighter than those detected in accelerators. The idea is based on an amazing effect around rotating black holes. Some hypothetical particles, called bosons...
