A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe.
The method can detect gravitational waves that oscillate just once every thousand years, 100 times slower than any previously measured gravitational waves.
Their new method of detection is based on analyzing pulsars, neutron stars that emit radio waves at highly regular intervals. Dror hypothesized that searching for gradual slowdown in the arrivals of these pulses could reveal new gravitational waves.
"Looking ahead, the next step is to analyze newer data sets," Dror said."The datasets we used were primarily from 2014 and 2015, and a huge number of pulsar observations have been undertaken since that time."
