Regular scalar clouds around a Kerr-Newman black hole: subextremal and extremal scenarios

Gustavo García, Marcelo Salgado

In this work we analyze the existence of electrically charged scalar clouds which are bound states of a complex-valued massive scalar field in the background of subextremal and ext…

High precision numerical sequences of rotating hairy black holes

Gustavo García, Eric Gourgoulhon, Philippe Grandclément +1

We analyze numerically the existence of regular stationary rotating hairy black holes within the framework of general relativity, which are the result of solving the Einstein-Klein…

Regular scalar charged clouds around a Reissner-Nordstrom black hole and no-hair theorems

Gustavo García, Marcelo Salgado

In this work we reanalyze the possibility of finding bound states (scalar clouds) of a test, charged and complex-valued scalar field with mass and charge q in the background of a R…

On the formation of "supermassive" neutron stars and dynamical transition to spontaneous scalarization

Juan Carlos Degollado, Marcelo Salgado, Miguel Alcubierre

It is well known that neutron stars can undergo a phase transition under a certain class of Scalar Tensor Theories of gravity (STT's) where a new order parameter, the {\it scalar c…

Solar System tests and chameleon effect in f (R) gravity

Carolina Negrelli, Lucila Kraiselburd, Susana J. Landau +1

Using a novel and self-consistent approach that avoids the scalar-tensor identification in the Einstein frame, we reanalyze the viability of f(R) gravity within the context of sola…

On the (non) existence of superregular boson clouds around extremal Kerr black holes and its connection with number theory

Gustavo Garcia, Marcelo Salgado

We argue about the (non) existence of {\it superregular} scalar clouds (i.e., bound states of a massive and complex-valued scalar field ) around exact {\it extremal} () K…
