Towards a deeper understanding of black hole origins
Research team studies the impact of remnant kicks on spin distributions of black holes from hierarchical mergers
A new study revisits modelling of the spin distributions from hierarchical binary black hole mergers in dense stellar environments, such as globular clusters. It finds clear deviations from the unique spin distribution described in previous studies, and shows a way to identify black holes from repeated mergers, which could help shed light on black hole formation through precise spin measurements in future observing runs.
