Motion of test bodies in theories with nonminimal coupling
Dirk Puetzfeld, Yuri N. Obukhov
We derive the equations of motion of test bodies for a theory with nonminimal coupling by means of a multipole method. The propagation equations for pole-dipole particles are worke…
Beyond linearized cosmology
Dirk Puetzfeld
We comment on the necessity of a unified approximative scheme within relativistic cosmology which would allow us to classify different cosmological models in a systematic way. We a…
Prospects of Non-Riemannian Cosmology
Dirk Puetzfeld
In this work we provide the motivation for considering non-Riemannian models in cosmology. Non-Riemannian extensions of general relativity theory have been studied for a long time.…
Complementary constraints from FR IIb radio galaxies and X-ray gas mass fractions in clusters on non-standard cosmological models
Dirk Puetzfeld, Martin Pohl, Zong-Hong Zhu
We use recent measurements of the dimensionless coordinate distances from Fanaroff-Riley Type IIb radio galaxies and the X-ray gas mass fractions in clusters to constrain the param…
