Globular Cluster Systems in Nearby Dwarf Galaxies: III. Formation Efficiencies of Old Globular Clusters

Understand

We investigate the globular cluster (GC) system scaling parameters as a function of galaxy mass, i.e.

• specific frequency (S_N), specific luminosity (S_L), specific mass (S_M), and specific number (^T) of GCs.
• We sample the entire range in galaxy luminosity (Mv = -11 to -23 mag = 10^6 - 10^11 L_sol), environment, and morphology.
• Irrespective of galaxy type, we confirm the increase of the S_N-value above and below a galaxy magnitude of Mv = -20 mag.
