Parallel session 6 (Black Holes Beyond GR)
- Session convener: Miguel Zilhão
The literature is flourishing in exotic and theoretical black hole solutions realized in the framework of general relativity or modified gravity theories to cure the singularity affecting the vacuum solutions of general relativity.
On the other hand, the Schwarzschild solution is the standard lore when computing constraints on primordial black hole abundance arising from the isotropic diffuse...
Higher-derivative terms are relevant in several approaches to quantum gravity. For instance, they occur in the perturbative quantization of Einstein gravity, and they can be used to construct (super-)renormalizable quantum gravity models. In this talk, we discuss the problem of whether higher derivatives could already resolve black hole singularities at classical level. To this end, we present...
In this talk, we will study the shadow, the greybody bounding, and the QNMs of a non-singular black hole in 4-dimensional spacetime in the context of scale-dependent gravity. Our focus is on determining constraints on the scale-dependent parameter, which serves as a descriptor for the scale-dependent solution with respect to the classically observed shadow radius. We also perform an analytical...
