A comprehensive dark matter analysis on the spiral galaxy NGC 4321 (M100) / Tan Wei Shen

The dark matter analysis on the spiral galaxy NGC 4321 (M100) is studied by considering the nine different dark matter profiles so far lacking in the scientific literature, i.e. Pseudoisothermal, Burkert, NFW, Moore, Einasto, core-modified, DC14, coreNFW and Lucky13 profiles. In this thesis, the rot...
