Jeans Newtonian and MOND modeling of the projected velocity dispersion of NGC 1407. The thick lines are for isotropic cases, and the thin lines are for fits based on β_lit. Upper panel: fits of the projected velocity dispersion of NGC 1407 using the Newtonian approach for the inner (“in”, solid lines) and outer (“out”, dashed lines) part. In the inner part, the thick blue line is for M/L_B = 7.2, and the thin blue line is for M/L_B = 10.0. In the outer part, the thick red line is for M/L_B = 42.8, and the thin red line is for M/L_B = 53.8. The NFW models with M_∗/L_B = 8.0, r_s = 550(650) arcsec, ρ_s = 0.0080(0.0070)) M_⊙ pc^-3 are shown with the thick (thin) dotted magenta lines. The thick dot-dashed magenta line is for the isotropic NFW model for which M/L_B = 6.5, r_s = 400 arcsec and ρ_s = 0.0070 M_⊙ pc^-3. Lower panel: again, the galaxy is split into its inner (“in”) and outer (“out”) part. The values of the mass-to-light ratio of the fits are as follows: for the standard MOND model, M/L_B = 7.0(37.0) for the inner (outer) part for the isotropic case and M/L_B = 9.0(45.4) for the inner (outer) part for the anisotropic case based on β_lit. For the simple MOND model, M/L_B = 5.6(27.0) for the inner (outer) part for the isotropic case, and M/L_B = 7.4(35.6) for the inner (outer) part for the anisotropic case based on β_lit. For the toy MOND model, M/L_B = 4.2(20.6) for the inner (outer) part for the isotropic case and M/L_B = 5.8(27.6) for the inner (outer) part for the anisotropic case based on β_lit. In both panels, one effective radius is indicated by a vertical dotted line.
