Cosmological simulations of the Santa Barbara cluster: the influence of scalar fields
M. A. Rodriguez-Meza
We present numerical N-body simulation studies of large-scale structure formation. The main purpose of these studies is to analyze the several models of dark matter and the role th…
Scalar-tensor cosmological simulations
M. A. Rodriguez-Meza
We present -body cosmlogical simulations in the framework of the Newtonian limit of scalar-tensor theories of gravity. The scalar field is described by a modified Helmholtz equa…
Cosmological simulations using a static scalar-tensor theory
M A Rodriguez-Meza, A X Gonzalez-Morales, R F Gabbasov +1
We present CDM -body cosmological simulations in the framework of a static general scalar-tensor theory of gravity. Due to the influence of the non-minimally coupled scalar f…
Flat rotation curves using scalar-tensor theories
Jorge L. Cervantes-Cota, M. A. Rodriguez-Meza, Dario Nunez
We computed flat rotation curves from scalar-tensor theories in their weak field limit. Our model, by construction, fits a flat rotation profile for velocities of stars. As a resul…
Newtonian limit of scalar-tensor theories and galactic dynamics: isolated and interacting galaxies
J. L. Cervantes-Cota, M. A. Rodriguez-Meza, R. Gabbasov +1
We use the Newtonian limit of a general scalar-tensor theory around a background field to study astrophysical effects. The gravitational theory modifies the standard Newtonian pote…
The influence of numerical parameters on tidally triggered bar formation
R. F. Gabbasov, M. A. Rodriguez-Meza, Jaime Klapp +1
The joint influence of numerical parameters such as the number of particles N, the gravitational softening length and the time-step is investigated in the context of galax…
