Title: Gravitational Wave Symphony from Oscillating Spectator Scalar Fields Abstract: Spectator scalar fields can be generically present in the early Universe, and are potentially dark matter candidates. We investigate the prospect of such scalars as a generic source of stochastic gravitational wave background (SGWB) due to parametric resonance during their oscillation phase. By systematically analyzing […]
