Conformal renormalization of scalar-tensor theories
Giorgos Anastasiou, Ignacio J. Araya, Mairym Busnego-Barrientos +2
We study a conformally coupled scalar-tensor theory with a quartic potential possessing local conformal symmetry up to a boundary term. We show that requiring the restoration of th…
Energy functionals from Conformal Gravity
Giorgos Anastasiou, Ignacio J. Araya, Rodrigo Olea
We provide a new derivation of the Hawking mass and Willmore energy functionals for asymptotically AdS spacetimes, by embedding Einstein-AdS gravity in Conformal Gravity. By constr…
CFT correlators from shape deformations in Cubic Curvature Gravity
Giorgos Anastasiou, Ignacio J. Araya, Andrés Argandoña +1
We find a covariant expression for the universal part of the holographic entanglement entropy which is valid for CFTs dual to generic higher curvature gravities in up to five bulk…
Extended primordial black hole mass functions with a spike
Juan Magaña, Marco San Martín, Joaquín Sureda +3
We introduce a modification of the Press-Schechter formalism aimed to derive general mass functions for primordial black holes (PBHs). In this case, we start from primordial power…
Dark matter from primordial black holes would hold charge
Ignacio J. Araya, Nelson D. Padilla, Marcelo E. Rubio +3
We explore the possibility that primordial black holes (PBHs) contain electric charge down to the present day. We find that PBHs should hold a non-zero net charge at their formatio…
Revisiting Viscous Transonic Decretion Disks of Be Stars
Michel Curé, Rodrigo Meneses, Ignacio Araya +4
In the context of Be stars, we restudied the viscous transonic decretion disk model of these stars. This model is driven by a radiative force due to an ensemble of optically-thin l…
