Imprint of Early Dark Energy in Stochastic Gravitational Wave Background
Chia-Feng Chang
Abstrak
Early dark energy that relieves Hubble tension leaves a fingerprint in the primordial stochastic gravitational wave (GW) background that originates from cosmic string network. The signal is not only detectable with future planned GW experiments, but also distinguishable from other astrophysical and cosmological signals in the GW frequency spectrum. We find that the cosmic string GW spectrum can probe other new physics that influence the universe in post-Big-Bang-Nucleosynthesis with mid-band GW detection, which extends GW cosmic archaeology search region.
