G-Warm inflation: Intermediate model
Ramon Herrera, Nelson Videla, Marco Olivares
A warm-intermediate inflationary universe model is studied in the presence of the Galileon coupling . General conditions required for successful inflation are deduced…
Motion and collision of particles near DST Black holes
P. A. González, Marco Olivares, Yerko Vásquez +2
We consider Deser-Sarioglu-Tekin (DST) black holes as background and we study such the motion of massive particles as the collision of two spinning particles in the vicinity of its…
Null paths on a toroidal topological black hole in conformalWeyl gravity
J. R. Villanueva, Francisco Tapia, Martín Molina +1
The motion of massless particles on the background of a toroidal topological black hole is analyzed in the context of conformal Weyl gravity. Null geodesics, in terms of the Jacobi…
G-inflation: From the intermediate, logamediate and exponential models
Ramon Herrera, Nelson Videla, Marco Olivares
The intermediate, logamediate and exponential inflationary models in the context of Galileon inflation or G-inflation are studied. By assuming a coupling of the form $G(ϕ,X)\propto…
Motion and collision of particles in rotating linear dilaton black hole
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We study the motion of particles in the background of a four-dimensional linear dilaton black hole. We solve analytically the equations of motion of the test particles and we descr…
