Description
Primordial black holes evaporate by Hawking radiation, leaving a stochastic gravitational-wave background today. Its spectrum is affected by the formation mass, angular momentum and initial abundance. In particular, the particle emission is greatly enhanced at high frequencies for fast-rotating black holes. In this work, we calculated this spectrum for a wide range of these parameters. Besides, we used the latest constraints on the abundance and found the upper bound on today's spectral density of gravitational waves.
Summary
A stochastic gravitational-wave background from primordial black holes is studied comprehensively.
