Could the NANOGrav signal be primordial?
Pulsar timing array experiments recently reported evidence for a background of gravitational waves traveling through the universe. Is it possible that this signal is primordial in origin?

Detecting high-frequency gravitational waves is a challenging task. Today’s paper proposes several novel experimental methods with promising sensitivities.
Can planetary magnetospheres be used as gravitational wave detectors? Find out in today’s paper!
Today we interview astrophysicist Kathryne Daniel for her plenary talk at #AAS242!
Have any gravitational wave signals been scrambled? Today’s authors search for this beyond-general relativity effect.
