Contribution
It introduces a model for black hole clusters formed in the early Universe and predicts gravitational wave burst rates detectable by LISA.
Findings
Predicted burst detection rate by LISA
Clusters of primordial black holes can seed supermassive black holes
Black hole mergers produce detectable gravitational wave bursts
Abstract
The rate of gravitational wave bursts from the mergers of massive primordial black holes in clusters is calculated. Such clusters of black holes can be formed through phase transitions in the early Universe. The central black holes in clusters can serve as the seeds of supermassive black holes in galactic nuclei. The expected burst detection rate by the LISA gravitational wave detector is estimated.
