Description

In recent years, several studies have explored the possibility that black-hole masses may be cosmologically coupled, allowing them to grow over cosmic time purely as a consequence of the expansion of the Universe. According to recent theoretical developments, the nature and strength of this coupling could depend on whether a singularity is present inside the event horizon. In this talk, I will present the first steps of a project aimed at incorporating such cosmological coupling into a population-synthesis framework. I will provide preliminary results illustrating how black-hole populations with and without central singularities would evolve differently. Finally, I will discuss how these distinct populations could be distinguished by future gravitational-wave interferometers.
