Description
This talk focuses on the dynamics of early primordial black hole binaries with a broad mass distribution. We highlight the subtleties that arise when calculating merger rates for these distributions and propose a framework to account for some of them. While the quest for a definitive rate remains ongoing, we provide critical insights into how mass-function variance impacts theoretical predictions. Finally, we present specific edge cases to demonstrate where current gravitational wave constraints remain robust, where they must be viewed with caution, and where they fail, depending on the underlying mass distribution.
