A team of scientists from the University of Amsterdam has carefully analyzed the gravitational waves produced during the merging of a neutron star with a black hole. Their findings suggest that the quality of streams is partially altered when, during the process, an area of dark matter is involved.
The study has revealed the existence of the QCD axion, entitled one of the most impressive dark matter candidates.
The results were obtained with the help of radion telescope observations that spotted the inner goings of the merging between black holes and neutron stars.
Which is the particular sign that could help dark matter detection?
The existence of such axions in the vicinity of the surface of the black hole while the converging process with a neutron star occurs impacts the gravitational waves.
The waves are modified in a distinctive manner, which allows scientists to determine a direct estimation of the density of the axions.
The axions’ density can be altered as well by the radion waves produced by the neutron star and its extremely strong magnetic fields. In addition to this, another particular trait of the axions occurs.
A unique radio wave signal is eliminated, allowing researchers to detect the presence of the dark matter easily.
Therefore, the gravitational wave signals combined with the radio signals recognized can undoubtedly influence the detection of QCD axion dark matter.
Conclusions from the leading researchers
This study was conducted by a group of scientists from the GRAPPA center of excellence, the groups Samaya Nissanke and Christoph Weniger.
The astrophysicists Thomas Edwards and Bradley Kavanagh are the leading researchers of this study.
The conclusion of the study suggests that the black holes have the capability of shedding light on the dark matter surrounding them, as observed with the help of specially designed equipment.
