Light rings in static and extremal black holes
P. Bargueno
In this work we establish some results concerning the existence of external light rings in extremal black hole spacetimes through the Newman-Penrose formalism. Specifically, assumi…

Complexity factor for black holes in the framework of the Newman-Penrose formalism
P. Bargueño, E. Fuenmayor, E. Contreras
In this work, we introduce the {\it complexity factor} in the context of self--gravitating fluid distributions for the case of black holes by employing the Newman-Penrose formalism…

Einstein-Klein-Gordon black holes by gravitational decoupling
Pio J. Arias, Pedro Bargueño, Ernesto Contreras +1
In this work we study the 2+1 Einstein-Klein-Gordon system in the framework of Gravitational Decoupling. We associate the generic matter decoupling sector with a real scalar field…
