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

Show Summary Details

Preview

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.
