Teukolsky equation for near-extremal black holes beyond general relativity: near-horizon analysis
Pablo A. Cano, Marina David
We study gravitational perturbations on the near-horizon region of extremal and near-extremal rotating black holes in a general higher-derivative extension of Einstein gravity. We…
Inconsistency of modified gravity in cosmology
Pablo A. Cano
We show that there is a fundamental flaw in the application of modified gravity theories in cosmology, taking gravity as a paradigmatic example. This theory contains a scala…
Regular Black Holes From Pure Gravity
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar
We show via an explicit construction how an infinite tower of higher-curvature corrections generically leads to a resolution of the Schwarzschild singularity in any spacetime dimen…
Boson stars with nonlinear sigma models
Pablo A. Cano, Ludovico Machet, Charlotte Myin
Boson stars arise as solutions of a massive complex scalar field coupled to gravity. A variety of scalar potentials, giving rise to different types of boson stars, have been studie…
