Test-particle dynamics in a noncommutative deformation of Einstein-Rosen waves
Diego Henrique Carvalho dos Santos, José André Lourenço, Davi C. Rodrigues +1
We investigate phenomenological effects induced by a noncommutative deformation of Einstein--Rosen gravitational-waves within the framework of the Riemannian geometry of noncommuta…
Relativistic and Newtonian Proca Stars: A Tale of Two Limits
Alberto Diez-Tejedor, Carlos Herdeiro, Claudio Lazarte +4
We investigate a representative set of static solitonic solutions of the Einstein-Proca theory in the Newtonian regime, where the field frequency approaches the particle mass, $ω\t…
Multipolar Proca stars: electric, magnetic and hybrid solitons
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho +1
We construct new families of everywhere regular, asymptotically flat solitons in the Einstein--Proca model, obtained as self-gravitating continuations of flat-spacetime (singular)…
From rotating attractors to extremal black holes with axionic hair
Etevaldo dos Santos Costa Filho
We study extremal, rotating black holes in four-dimensional Einstein-Maxwell-axion (EMA) theory through a combined near-horizon and bulk analysis. At the level of the near-horizon…
Spinning extremal dyonic black holes in Einstein-Maxwell-dilaton theory
Jose Luis Blázquez-Salcedo, Carlos Herdeiro, Eugen Radu +2
We propose a general framework for the study of asymptotically flat spinning dyonic {\it extremal} black holes (eBHs) in Einstein-Maxwell-dilaton theory. Restricting to the s…
Charged, rotating black holes in Einstein-Maxwell-dilaton theory
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho
The asymptotically flat, electrically charged, rotating black holes (BHs) in Einstein-Maxwell-dilaton (EMd) theory are known in closed form for \textit{only} two particular values…
