NGC 5128's globular cluster system: Is there a dark side?

Resultado de la investigación: Article

Resumen

Dynamical mass estimates (Mdyn) and mass-to-light ratios (Ydyn) were derived for a sample of NGC 5128's globular clusters (GCs). We find two distinct sequences in the Ydyn-Mdyn plane, which are well fit by power laws of the forms Ydyn ∝ Mdyn0.33±0.04 and Ydyn ∝ Ydyn0.91±0.04. The former traces bright "classical" GCs, and the latter represents objects that are dynamically dominated by large dark matter components or by abnormally massive central black holes.
