Shadows of rotating black holes in alternative theories
Leonardo Amarilla, Ernesto F. Eiroa
We briefly review some recent advances in the study of the shadows of rotating black holes in alternative theories. The size and the shape of the shadow depend on the mass and the…
Shadow cast by a Kaluza-Klein spinning dilaton black hole
Leonardo Amarilla, Ernesto F. Eiroa
We examine the shadow of a rotating Kaluza-Klein black hole in Einstein gravity coupled to a Maxwell field and a dilaton. The size and the shape of the shadow depend on the mass, t…
Shadow of a Kaluza-Klein rotating dilaton black hole
Leonardo Amarilla, Ernesto F. Eiroa
We study the shadow produced by a spinning Kaluza-Klein black hole in Einstein gravity coupled to a Maxwell field and a dilaton. The size and the shape of the shadow depend on the…
Shadow of a rotating braneworld black hole
Leonardo Amarilla, Ernesto F. Eiroa
We investigate the shadow cast by a rotating braneworld black hole, in the Randall-Sundrum scenario. In addition to the angular momentum, the tidal charge term deforms the shape of…
Null geodesics and shadow of a rotating black hole in extended Chern-Simons modified gravity
Leonardo Amarilla, Ernesto F. Eiroa, Gaston Giribet
The Chern-Simons modification to general relativity in four dimensions consists of adding to the Einstein-Hilbert term a scalar field that couples to the first class Pontryagin den…
Brane-world cosmology and varying
Leonardo Amarilla, Hector Vucetich
We consider a brane-world cosmological model coupled to a bulk scalar field. Since the brane tension turns out to be proportional to Newton coupling , in such a model a time var…
