EPTA (European Pulsar Timing Array)

The European Pulsar Timing Array (EPTA) is a scientific community that uses highly precise measurements of pulsars—rotating neutron stars emitting regular radio signals—to detect low-frequency gravitational waves, ripples in spacetime caused by massive cosmic events. By monitoring an array of these pulsars across Europe, EPTA searches for tiny variations in signal arrival times that indicate passing gravitational waves. This approach helps scientists study phenomena like merging supermassive black holes, deepening our understanding of the universe's structure and evolution through gravitational wave astronomy.
