A comprehensive analysis using 9 dark matter halo models on the spiral galaxy NGC 4321

This paper addressed the dark matter analysis on spiral galaxy NGC 4321 (M100) by considering nine different profiles, so far lacking in scientific literature, i.e., pseudoisothermal, Burkert, NFW, Moore, Einasto, core-modified, DC14, coreNFW and Lucky13 profiles. In this paper, we analyzed rotation curve using nonlinear fitting of star, gaseous halo equations with selected VLA HI observation data. Among four profiles (DC14, Lucky13, Burkert Moore profiles) showed declining features hence not suitable for galaxy. is concluded to be mainly due characteristics those also varying levels problems within inner region fittings. For remaining five accepted further conducted reduced Chi-square test. Four out lie range 0.40 < $$\chi _{\mathrm{red}}^2$$ 1.70, except core-modified profile. addition, pseudoisothermal profile achieved best nearest 1, its linearity flatness at large radii.
