Globular Cluster Evolution in M87 and Fundamental Plane Ellipticals
The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamental plane ellipticals in general, cluster populations evolve more rapidly in smaller galaxies because of the higher mass density. A simple evolutionary model reproduces the observed trend in specific frequency with lu...

متن کاملThe Fundamental Plane of Cluster Ellipticals at Z = 1.25
Using deep HST ACS imaging and VLT FORS2 spectra, we determined the velocity dispersions, effective radii and surface brightnesses for four early-type galaxies in the z = 1.237 cluster RDCS 1252.9-2927. All four galaxies are massive, > 10 11 M ⊙. These four galaxies, combined with three from RDCS 0848+4453 at z = 1.276, establish the Fundamental Plane of massive early-type cluster galaxies at ¯...
متن کاملThe fate of cannibalized fundamental-plane ellipticals
Evolution and disruption of galaxies orbiting in the gravitational field of a larger cluster galaxy are driven by three coupled mechanisms: 1) the heating due to its time dependent motion in the primary; 2) mass loss due to the tidal strain field; and 3) orbital decay. Previous work demonstrated that tidal heating is effective well inside the impulse approximation limit. Not only does the overa...
متن کاملOn the Fundamental Plane of the Galactic Globular Cluster System
Context. The globular clusters of our Galaxy have been found to lie close to a plane in the log Re, logσ, SBe space (see Djorgovski 1995), on the continuation of the Fundamental Plane that is known to characterize the global properties of early-type galaxies. Of course, there is no apparent reason why such physically different self-gravitating systems should follow the same scaling law. Aims. W...
