Following a number of discrepant studies of M87’s mass prole, we carry out an extensive dynamical analysis of multiple tracer populations in this giant elliptical galaxy in order to constrain its mass over a large radius range. We combine stellar kinematics in the central regions with the dynamics of 612 globular clusters out to 200 kpc and satellite Virgo galaxies on scales comparable with the virial radius of the cluster. Using a spherically symmetric Jeans analysis, we are able to… Expand

Galactic Dark Matter Halos and Globular Cluster Populations. III: Extension to Extreme Environments
The total mass M_GCS in the globular cluster (GC) system of a galaxy is empirically a near-constant fraction of the total mass M_h = M_bary + M_dark of the galaxy, across a range of 10^5 in galaxyExpand
Is there substructure around M87
We present a general method to identify infalling substructure in discrete datasets with position and line-of-sight velocity data. We exploit the fact that galaxies falling onto a brightest clusterExpand
The Fundamental Plane of evolving red nuggets
We present an exploration of the mass structure of a sample of 12 strongly lensed massive, compact early-type galaxies at redshifts z ∼ 0.6 to provide further possible evidence for their inside-outExpand
The most massive galaxies in clusters are already fully grown at z ∼ 0.5
By constructing scaling relations for galaxies in the massive cluster MACSJ0717.5 at z = 0.545 and comparing with those of Coma, we model the luminosity evolution of the stellar populations and theExpand
