Structural parameters for globular clusters in NGC 5128 – III. ACS surface brightness profiles and model fits
Abstract
We present internal surface brightness profiles, based on Hubble Space Telescope/ACS imaging in the F606W bandpass, for 131 globular cluster (GC) candidates with luminosities L≃ 104–3 × 106L⊙ in the giant elliptical galaxy NGC 5128. Several structural models are fitted to the profile of each cluster and combined with mass-to-light ratios (M/L values) from population-synthesis models, to derive a catalogue of fundamental structural and dynamical …
