Gravitational wave forest from string axiverse
Gravitational wave forest from string axiverse is a scholarly work, published in 2018 in ''Journal of Cosmology and Astroparticle Physics''. The main subjects of the publication include scalar potential, axion, string theory, physics, gravitational wave, particle physics, dark matter, string, flapping, resonance, scalar, astrophysics, and gravity. The authors find that string axions in\nvarious mass ranges generate gravitational waves (GWs) with peaks at various\nfrequencies determined by the mass scales, dubbed the GW forest.
