Forecast constraints on cosmic strings from future CMB, pulsar timing and gravitational wave direct detection experiments

Understand

We study future observational constraints on cosmic string parameters from various types of next-generation experiments: direct detection of gravitational waves (GWs), pulsar timing array, and the cosmic microwave background (CMB).

• We consider both GW burst and stochastic GW background searches by ground- and space-based interferometers as well as GW background detection in pulsar timing experiments.
• We also consider cosmic string contributions to the CMB temperature and polarization anisotropies.
• These different types of observations offer independent probes of cosmic strings and may enable us to investigate cosmic string properties if the signature is detected.
