Scattering of quantum fields by a MOG Black Hole
Ciprian A. Sporea
This paper aims to investigate the scattering of fermions by spherically symmetric MOG black holes, which are a type of black holes encountered in scalar-tensor-vector modified gra…
Scattering of Dirac fermions by spherical massive bodies
Ion I. Cotaescu, Ciprian A. Sporea
The asymptotic form of Dirac spinors in the field of a Schwarzschild black hole is used for deriving analytically for the first time the phase shifts of the partial wave analysis o…
Fermion scattering by a class of Bardeen black holes
Ciprian A. Sporea
In this paper the scattering of fermions by a class of Bardeen black holes is investigated. After obtaining the scattering modes by solving the Dirac equation in this geometry, we…
A simple model for explaining Galaxy Rotation Curves
Aneta Wojnar, Ciprian A. Sporea, Andrzej Borowiec
A new simple expression for the circular velocity of spiral galaxies is proposed and tested against HI Nearby Galaxy Survey (THINGS) data set. Its accuracy is compared with the one…
