Exact General Relativistic Discs and the Advance of Perihelion
D. Vogt, P. S. Letelier
The advance of perihelion for geodesic motion on the galactic plane of some exact general relativistic disc solutions is calculated. Approximate analytical and numerical results ar…
Triaxial Analytical Potential-Density Pairs for Galaxies
Daniel Vogt, Patricio S. Letelier
We present two triaxial analytical potential-density pairs that can be viewed as generalized versions of the axisymmetric Miyamoto and Nagai and Satoh galactic models. These potent…
Exact General Relativistic Rotating Disks Immersed in Rotating Dust Generated from van Stockum Solutions
D. Vogt, P. S. Letelier
A class of exact general relativistic rotating thick disks surrounded by rotating dust is constructed by applying the ``displace, cut, fill and reflect'' method on the van Stockum…
On Multipolar Analytical Potentials for Galaxies
D. Vogt, P. S. Letelier
We present analytical potential-density pairs in three dimensions for the gravitational field of galaxies, obtained by thickening the multipolar expansion up to the quadrupole term…
Comments on "Perspectives on Galactic Dynamics via General Relativity"
D. Vogt, P. S. Letelier
In this comment we question some arguments presented in astro-ph/0512048 to refuse the presence of an singular mass surface layer. In particular, incorrect expressions are used for…
Presence of exotic matter in the Cooperstock and Tieu galaxy model
D. Vogt, P. S. Letelier
We analyze the presence of an additional singular thin disk in the recent General Relativistic model of galactic gravitational field proposed by Cooperstock and Tieu. The physical…
