Clouds of ultralight particles can form around dark circular holes. A team of physicists from the University of Amsterdam and Harvard University now suggests that these clouds will leave a mark on the gravitational waves emitted by double black holes.
Black holes are often thought to swallow all kinds of material and energy, and however, it has long been known that they can no longer waste one of their masses through superradiance. Although this phenomenon is known to be possible, it only works if new, to date invisible particles with low concentrations are present in nature, as several theories have been predicted beyond the Standard Model of particle physics.
Ionizing atoms pull down.
When a mass is extracted from a black hole using high light, it forms a giant cloud around the black hole, forming a magnetic field. Despite the large size of the atomic force atom, comparisons with smaller particles are accurate due to the similarity of the black hole and its cloud to the typical structure of ordinary atoms, where electron clouds surround the nucleus of protons and neutrons.
This week, a letter from Physical Review Letters, a team comprising UvA scholars Daniel Baumann, Gianfranco Bertone, Giovanni Maria Tomaselli, and Harvard University physicist John Stout suggests comparisons between ordinary atoms and gravity are much deeper than just atoms. Structural similarity: they say that parallels can identify new particles with gravitational waves in future interferometers.
Researchers have learned the subtle proportions of the so-called “photoelectric effect in new work.” In this well-known process, for example, used in solar cells to generate electricity, ordinary electrons absorb the energy of light events and release them from matter — atoms “ionize.” In the analog of gravity, where the atom of gravity is part of a binary system of two heavy objects, it is disturbed by the presence of a large companion, either a second black hole or a neutron star. Just as the electrons in the electromagnetic field absorb the light of an event light, the ultralight light particles can absorb the corresponding rotation energy so that another cloud is released from the atom’s magnetic field.
