Research topics outline
» Dark matter and dark matter-like effects: concerns the standard expectations for dark matter and changes on its nature or abundance due to nontrivial gravitational effects.
» Extensions of General Relativity: Renormalization group extended general relativity, scalar-tensor gravity, screening mechanisms...
» Galaxy modelling: Mass profiles, rotation curves, dispersion velocity curves, the core/cusp issue and other small scale issues, model testing and comparison, dark matter halo profiles, non-Newtonian models that mimic partially or completely dark matter, the Radial Acceleration Relation....

Galaxy mass modelling from diverse approaches and programming.
All the codes below were written for Wolfram Mathematica. If you would like to use any of them please let me know (@cosmo-ufes.org).
» Fast GR symbols Evaluation (FGeV). A fast and simple program to evaluate tensors, for a given metric, that are commonly used in General Relativity. It also evaluates perturbations. I used it in many papers, the first one was .
» Galaxy Mass modelling from Rotation curve (GMRot). I used it in many papers on disk galaxies, see in particular , the first paper was .
» Galaxy Mass modelling from Velocity Dispersion (GMVD). Similar to GMRot, but for elliptical galaxies. Used in .
» Galaxy Sample Data Analysis (GSDA). Uses the output of GMRot to do diverse data analysis. Used in [2, 5].
» MAGMA - Mathematica Automatised Galaxy Mass Analysis. A complete and fully automatised code to fit a model using a large sample of galaxies. It also generates plots for each galaxy and a table with the final results from the sample. To be released at https://github.com/davi-rodrigues/MAGMA . Used in [to appear].
