On a Theory for Nonminimal Gravitational-electromagnetic Coupling Consistent with Observational Data
نویسنده
چکیده
The idea that the seed primordial magnetic fields can be explained by the nonminimal coupling between gravitational and electromagnetic fields is discussed. The predicted values of the magnetic field of the spiral galaxies are in agreement with the observations.

BROWN HET-1070 Origin of Magnetic Fields in the Universe Due to Nonminimal Gravitational-Electromagnetic Coupling
Basically the only existing theories for the creation of a magnetic field (B) in the Universe are the creation of a seed field ∼ 10 G in spiral galaxy which is subsequently supposedly amplified up to the observed 10—10 G by a dynamo process or a seed intergalactic field of ∼ 10—10 G which is amplified by collapse and differential rotation. No satisfactory dynamo theory, however, exists today. W...
متن کاملDensity perturbations in generalized Einstein scenarios and constraints on nonminimal couplings from the Cosmic Microwave Background
We study cosmological perturbations in generalized Einstein scenarios and show the equivalence of inflationary observables both in the Jordan frame and the Einstein frame. In particular the consistency relation relating the tensor-to-scalar ratio with the spectral index of tensor perturbations coincides with the one in Einstein gravity, which leads to the same likelihood results in terms of inf...
متن کاملAn astronomical search for evidence of new physics: Limits on gravity-induced birefringence from the magnetic white dwarf RE J0317-853
The coupling of the electromagnetic field directly with gravitational gauge fields leads to new physical effects that can be tested using astronomical data. Here we consider a particular case for closer scrutiny, a specific nonminimal coupling of torsion to electromagnetism, which enters into a metric-affine geometry of space-time. We show that under the assumption of this nonminimal coupling, ...

A covariant scalar-tensor-vector gravity theory is developed which allows the gravitational constant G, a vector field coupling ω and the vector field mass μ to vary with space and time. The equations of motion for a test particle lead to a modified gravitational acceleration law that can fit galaxy rotation curves and cluster data without non-baryonic dark matter. The theory is consistent with...
