Hierarchical formulation of the self-gravitating, n-dimensional, charged scalar field in spherical symmetry in affine null formalism
Laura Bridera, Emanuel Gallo, Thomas Mädler
We develop an affine-null characteristic formulation of the Einstein-Maxwell system coupled to a charged complex scalar field in -dimensional spherical symmetry. By introducing…
Hadronic lensing
Fabrizio Canfora, Cristóbal Corral, Borja Diez
We introduce an analytic approach to study gravitational lensing in the presence of a distribution of hadrons. The situation is analogous to the propagation of photons in a medium…
Generation of gravitating solutions with Baryonic charge from Einstein-Scalar-Maxwell seeds
Fabrizio Canfora, Anibal Neira, Seung Hun Oh
We establish, for the first time, an exact correspondence between Einstein-scalar-Maxwell theory and gauged Skyrme-Maxwell-Einstein models in (3+1) dimensions. By constructing the…
Exact plane symmetric black bounce with a perfect-fluid exterior obeying a linear equation of state
Hideki Maeda, Cristian Martinez
We investigate an exact two-parameter family of plane symmetric solutions admitting a hypersurface-orthogonal Killing vector in general relativity with a perfect fluid obeying a li…
Planar black holes and wormholes with a flat exterior
Hideki Maeda, Cristian Martinez
We present -dimensional planar black holes and wormholes with a flat exterior, which are originated by an exact solution in general relativity. The nonvacuum regions of t…
Exact analytic solutions in 2+1 Hořava gravity with cosmological constant
Jorge Bellorín, Claudio Bórquez, Byron Droguett
We investigate the static solutions with rotational symmetry in the nonprojectable Ho\v rava theory in \(2+1\) dimensions. We consider all inequivalent terms of the effective theor…
Junction conditions for higher order gravity theories from a Gibbons-Hawking-York boundary term
Marcos A. Ramirez, Cristián Martínez
In this work we study the problem of generalizing the Gibbons-Hawking-York boundary terms for general quadratic theories of gravity and propose a simple condition to obtain them. F…
Neutron stars in 4D Einstein-Gauss-Bonnet gravity
Alejandro Saavedra, Octavio Fierro, Michael Gammon +2
Since the derivation of a well-defined limit for 4D Einstein-Gauss-Bonnet (4DEGB) gravity coupled to a scalar field, there has been considerable interest in testing it as a…
Existence and absence of Killing horizons in static solutions with symmetries
Hideki Maeda, Cristian Martinez
Without specifying a matter field nor imposing energy conditions, we study Killing horizons in -dimensional static solutions in general relativity with an -dimensi…
Asymptotically AdS black hole with a conformally-coupled scalar field in the first-order formalism of gravity
L. Avilés, C. Corral, F. Izaurieta +2
We present a novel asymptotically anti-de Sitter black hole solution with conformally-coupled scalar fields in the first-order formalism of gravity in four dimensions. To do so, we…
A Universe from a Lagrangian Fixed Point
Pedro D. Alvarez, Benjamin Koch, Ali Riahinia +1
In this paper, we investigate the theoretical possibility that a Lagrangian fixed point, when applied to cosmological models, can drive dynamical evolution towards a bouncing unive…
Five-dimensional Einstein-Chern-Simons cosmology
Fernando Gómez, Samuel Lepe, Cristian Quinzacara +1
We consider a five-dimensional Einstein-Chern-Simons action which is composed of a gravitational sector and a sector of matter, where the gravitational sector is given by a Chern-S…
Static phantom wormholes of finite size
Mauricio Cataldo, Fabian Orellana
In this paper we derive new static phantom traversable wormholes by assuming a shape function with a quadratic dependence on the radial coordinate r. We mainly focus our study on w…
Static solutions in Einstein-Chern-Simons gravity
Juan Crisóstomo, Fernando Gomez, Patricio Mella +2
In this paper we study static solutions with more general symmetries than the spherical symmetry of the five-dimensional Einstein-Chern-Simons gravity. In this context, we study th…
Accelerated FRW Solutions in Chern-Simons Gravity
Juan Crisostomo, Fernando Gomez, Patricio Salgado +3
We consider a five-dimensional Einstein-Chern-Simons action which is composed of a gravitational sector and a sector of matter, where the gravitational sector is given by a Chern-S…
