Very happy to see my new paper with Marco Calzà, Davide Pedrotti, and Max Rinaldi out today, making it yet one more paper 100% produced within the Theoretical Gravitation and Cosmology Group led by myself and Max! We study cosmologically coupled black holes (CCBHs), which have gained tremendous interest recently, including as possible candidates for driving cosmic acceleration. All studies on CCBHs so far were purely classical, and neglected the fact that CCBHs will inevitably evaporate: we therefore asked ourselves how evaporating CCBHs would behave. After discussing in detail how evaporating CCBHs can be modelled (which in turn required us to adopt a controlled quasi-adiabatic approxiation), we showed that these objects can have a very rich phenomenology, and we derived the first constraints on their abundance. You can read our results in the preprint we just posted on arXiv: 2607.13857.
