A constellation of gravitational wave observatories could pinpoint the incredibly faint signals from merging black holes.
Since 2015, scientists have detected about 100 black hole mergers thanks to gravitational waves emanating from the cataclysmic events.
That's only a tiny fraction of the hundreds of thousands of black hole mergers that scientists believe take place every year. Now, a team of scientists from the International School for Advanced Studies in Italy has published a new paper inl detailing how a constellation of interferometers could allow astronomers to detect many more black hole mergers than is possible with current technologies.Interferometers are instruments used across many different fields of science and engineering to measure the way two different light waves interfere with one another.
In their paper, the researchers outline how their constellation of several LISA-like detectors could combine their observations to effectively isolate anisotropies. The researchers say their idea would allow for a much higher resolution, which would be crucial for detecting such faint signals amid the noise of the SGWB.
