- Abstract: Black holes exhibit gravitational and quantum effects that lead to potential observables and insights into Effective Field Theories (EFTs) with gravity. In this presentation, I will discuss the charge radiation of black holes and its theoretical implications. The computation of charged particle creation, the Schwinger effect, of black holes, will be presented. For highly charged (extremal) black holes, the emission spectrum truncates below a threshold value of the particle’s charge-to-mass ratio. This result will then be used to formulate the Weak Gravity Conjecture (WGC), which provides a potential constraint on consistent EFTs. Features of black holes in de Sitter space (\Lambda>0), such as their thermodynamics and (in)stabilities will be discussed.
