Cosmological constraints on viable models using weak lensing
Leandro Pardo, Leonardo Castañeda
The accelerated expansion of the Universe remains one of the central open problems in modern cosmology. While the CDM model successfully describes a wide range of observations,…

Gravitational lensing by a generalised-NFW halo via the Fox -function and its application to the super-NFW
Daniel Alexdy Torres-Ballesteros, Leonardo Castañeda
We present an analytical framework for a family of axisymmetric gravitational lenses, in which we express the lensing properties in terms of the Fox -function. We apply this fra…

Gravitomagnetic effects of a massive and slowly rotating sphere with an equatorial mass current on orbiting test particles
L. Castaneda, F. Fandino, W. Almonacid +2
Within the framework of linearized Einstein field equations we compute the gravito-magnetic effects on a test particle orbiting a slowly rotating, spherical body with a rotating ma…
