Physics Beyond the Standard Model With Pulsar Timing Arrays
·
Abstract
Pulsar timing arrays provide a rare opportunity to probe exotic physics. Potential sources of gravitational waves (GWs) in the nanohertz band include cosmic strings, inflation, and early universe phase transitions. GW observations will also make possible new tests of gravitational theories and provide a means to probe certain dark matter models.
