Searching for Gravitational Waves with Pulsars
Pulsars, rapidly spinning neutron objects, offer a distinctive method for observing gravitational disturbances. Unlike conventional ground-based instruments, which depend on incredibly sensitive laser interferometry, pulsar timing networks examine subtle changes in the arrival of radio pulses. Each pulsar radiates a highly regular signal, acting as a cosmic timer. A passing gravitational wave would slightly distort space, causing tiny alterations in the pulse receipt. These minute changes, when combined across a extensive array of pulsars, can, in theory, reveal the detection of a residual gravitational wave signal, possibly originating from supermassive black hole mergers.
