Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
Invariant Renormalization-Group improvement
Aaron Held
Renormalization-Group (RG) improvement has been frequently applied to capture the effect of quantum corrections on cosmological and black-hole spacetimes. This work utilizes an alg…
Destabilization of black holes and stars by generalized Proca fields
Sebastian Garcia-Saenz, Aaron Held, Jun Zhang
We demonstrate that black holes and stars in general relativity can be destabilized by perturbations of non-minimally coupled vector fields. Focusing on static and spherically symm…
Nonlinear Dynamics of Quadratic Gravity in Spherical Symmetry
Aaron Held, Hyun Lim
We present the first numerically stable nonlinear evolution for the leading-order gravitational effective field theory (Quadratic Gravity) in the spherically-symmetric sector. The…
From a locality-principle for new physics to image features of regular spinning black holes with disks
Astrid Eichhorn, Aaron Held
Current observations present unprecedented opportunities to probe the true nature of black holes, which must harbor new physics beyond General Relativity to provide singularity-fre…
Image features of spinning regular black holes based on a locality principle
Astrid Eichhorn, Aaron Held
To understand the true nature of black holes, fundamental theoretical developments should be linked all the way to observational features of black holes in their natural astrophysi…
