The Globular Cluster Systems around NGC 3311 and NGC 3309
Abstract
We present extensive new photometry in (g′, i′) of the large globular cluster (GC) system around NGC 3311, the central cD galaxy in the Hydra cluster. Our GMOS data cover a 5.5′ field of view and reach a limiting magnitude i′ ≃ 26.0, about 0.5 mag fainter than the turnover point of the GC luminosity function. We find that NGC 3311 has a huge population of ≃16,000 GCs, closely similar to the prototypical “high specific frequency” Virgo giant …
