SEMICLASSICAL VIOLATION of THE EQUIVALENCE PRINCIPLE IN THE GRAVITATIONAL LENSES REALM
(World Scientific Publ Co Pte Ltd, 2009-12-31)
An expression for the gravitational deflection angle of a high-energy massless scalar boson is computed using the JWKB method. The resulting expression depends on the energy of the scalar boson or, equivalently, on its ...

Microlensing Analysis for the Gravitational Lens Systems SDSS0924+0219, Q1355-2257, and SDSS1029+2623
(The American Astronomical Society, 2020)
We use spectroscopic observations of the gravitationally lensed systems SDSS0924+0219(BC), Q1355-2257(AB), and SDSS1029+2623(BC) to analyze microlensing and dust extinction in the observed components. We detect chromatic ...
Lentes plasmáticas en entornos de objetos compactos
(2022-03-28)
La deflexión de la luz por potenciales gravitatorios es un fenómeno clásico de la Relatividad General. Es sabido que objetos compactos generan efectos de lente gravitacional convergente.
En este trabajo, estudiaremos como ...
Chromaticity effects in microlensing by wormholes
(World Scientific, 2001-12)
We discuss the possibility that the stellar system Cyg OB2 No. 5 can be a gamma-ray source in the light of recent EGRET and radio data. This system is formed by an O7 Ia + Ofpe/WN9 contact binary. A third star, probably a ...
Microlensing in H1413+117: disentangling line profile emission and absorption in a broad absorption line quasar
(2010)
On the basis of 16 years of spectroscopic observations of the four components of the gravitationally lensed broad absorption line (BAL) quasar H1413+117, covering the ultraviolet to visible rest-frame spectral range, we ...
