A possible influence of magnetic fields on the rotation of gas in NGC 253


E-mail: Lukasz.Bratek@ifj.edu.pl


The magnetic fields that are present in the galaxy NGC 253 are exceptionally strong. This means that they can influence the rotation of matter and hence the mass-to-light ratio. In this context, we address the issue of the presence of a non-baryonic dark matter halo in this galaxy.
