Abstract

VLT images in BVI are used to identify globular clusters in the central region of NGC5128. Based on the sizes, optical magnitudes and colors, a hundred candidate globular clusters are identified with projected galactocentric distances 1 kpc < RG < 5 kpc. These clusters have magnitudes 18 < V < 20.5 or -10.3 < MV < -7.8 at the distance of this galaxy, and colors 0.8 < V - I < 1.5 and 0.5 < B - V < 1.5. These identifications allow us to compare the properties of the X-ray globular cluster population discovered recently in this galaxy.
