Long Talk (20 mins) Black Holes


Lewis Croney (King's College London)


Primordial black holes could play a significant role in cosmological history, yet fully consistent treatments of their evolution remain limited. The well-known paradigm of slow-roll inflation treats a slowly evolving scalar field in an isotropic universe, and some authors have extended this to include a spherically symmetric black hole. In this talk, I will discuss recent analytic progress on understanding slowly-rolling scalar fields in rotating black hole backgrounds, representing a significant increase in the complexity of the problem. I will compare this with earlier treatments and results, which often neglect cosmological expansion.
