WebMay 1, 2024 · The sensitivity of Pulsar Timing Arrays to gravitational waves depends critically on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the pulsar. WebThe pulsar timing array (PTA) is a method to detect nano Hertz gravitational waves. At present, there are basically three PTA collaborations in the world, including the European …
WebJan 25, 2024 · Pulsar Timing Array Experiments. Pulsar timing is a technique that uses the highly stable spin periods of neutron stars to investigate a wide range of topics in physics and astrophysics. Pulsar timing arrays (PTAs) use sets of extremely well-timed pulsars as a Galaxy-scale detector with arms extending between Earth and each pulsar in the array.
