Box 19395-5531, Tehran, Iran aut Phenomenological covariant approach to gravity [Elektronische Daten] [Qasem Exirifard] We covariantly modify the Einstein-Hilbert action such that the modified action perturbatively resolves the anomalous rotational velocity curve of the spiral galaxies and gives rise to the Tully-Fisher relation, and dynamically generates the cosmological constant. This modification requires introducing a single new universal parameter. It requires inclusion of neither dark matter nor dark energy.
