GLOBULAR CLUSTER SCALE SIZES IN GIANT GALAXIES: THE CASE OF M87 AND THE ROLE OF ORBITAL ANISOTROPY AND TIDAL FILLING
Abstract
We present new Hubble Space Telescope imaging of the outer regions of M87 in order to study its globular cluster (GC) population out to large galactocentric distances. We discuss, particularly, the relationship between GC effective radii rh and projected galactocentric distance Rgc. The observations suggest a shallow trend out to Rgc ∼ 100 kpc, in agreement with studies of other giant elliptical galaxies. To theoretically reproduce this …
