Rotation Curve Fitting Model
One key piece of evidence for dark matter is the flat rotation curve problem:
the disagreement between measured galactic rotation curves and their luminous
mass. A novel solution to this problem is presented here. A model of
relativistic frame effects on Doppler shifts due to the slightly curved frames
of an emitting galaxy and the Milky Way is derived. This model predicts
observed Doppler shifted spectra (in excess of the luminous mass) based only on
the observed luminous matter profile and one free model parameter. Fits to the
175 galaxies reported in the SPARC database of galactic rotation profiles and
accurate photometry measurements are compared between this novel model and dark
matter and MOND (RAR) models. We find on the SPARC sample of 175 galaxies; that
MOND-RAR has an average reduced chisquare of for 175 galaxies
fitted, the isothermal dark matter model has for 165 galaxies
fitted, and the new model we present has for 172 galaxies
fitted. Implications of this model are discussed.Comment: 27 pages, 9 figure
