For my Ph.D. work, I created 36 high resolution galaxy rotation curves using the Spitzer I-band for spiral galaxies in the Ursa Major (UMa) filament, and dissected the components into stellar, gaseous, and modelled both the dark matter components using both the NFW profile, and a core-modified dark matter profile, and compared these results to the alternative provided by Modified Gravity (MoG) and Modified Newtonian Dynamics (MOND).

The figures below show the Spitzer data, computed as Surface-Mass Densities (Σ(R); left panel), and corresponding galaxy rotation curves (v(R); right panel), derived for both high-surface brightness (HSB) and low-surface brightness (LSB) galaxies targetted in the Ursa Major (UMa) filament of galaxies.
