Nanohertz Gravitational Waves

(Nanohertz GWs)
(size of GWs that pulsar-timing observations might catch)

Nanohertz Gravitational Waves (Nanohertz GWs) are Gravitational Waves with a Frequency on the order of 10-9 Hertz, i.e., with a period of about 30 years. Speculated sources for this range include:

Pulsar timing arrays (e.g., NANOGrav) are sensitive to GWs in the range of 10-5 Hz to 10-10 Hz, i.e., periods from about a day to about 300 years. Probably the nanohertz range is being investigated because the means of detection exists and is freely available.
