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
Galaxy structure from multiple tracers - III. Radial variations in M87's IMF
We present the first constraints on stellar mass-to-light ratio gradients in an early-type galaxy (ETG) using multiple dynamical tracer populations to model the dark and luminous mass structureExpand
The SLUGGS Survey: The Inner Dark Matter Density Slope of the Massive Elliptical Galaxy NGC 1407
We investigate the dark matter density profile of the massive elliptical galaxy, NGC 1407, by constructing spherically symmetric Jeans models of its field star and globular cluster systems. Two majorExpand
Revisiting the bulge-halo conspiracy I: Dependence on galaxy properties and halo mass
We carry out a systematic investigation of the total mass density profile of massive (Mstar>2e11 Msun) early-type galaxies and its dependence on galactic properties and host halo mass with the aid ofExpand
The SLUGGS survey: the mass distribution in early-type galaxies within five effective radii and beyond
We study mass distributions within and beyond 5 effective radii (Re) in 23 early-type galaxies from the SAGES Legacy Unifying Globulars and Galaxies Survey, using their globular cluster (GC)Expand
Sizes of the stellar subsystems of galaxies and intracluster stars in the Virgo cluster
Stellar photometry for three fields in the Virgo cluster of galaxies has been performed on the basis of archival Hubble Space Telescope ACS/WFC images. The densely populated red giant branchesExpand
The Assembly History of M87 through Radial Variations in Chemical Abundances of Its Field Star and Globular Cluster Populations
We present an extensive study of spectroscopically-derived chemical abundances for M87 and its globular cluster (GC) system. Using observations from the Mitchell spectrograph at McDonald, LRIS atExpand
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


Galaxy structure from multiple tracers – I. A census of M87's globular cluster populations

The Dark Matter Distribution in the Central Regions of Galaxy Clusters
Cosmological N-body simulations predict that dark matter halos should have a universal shape characterized by a steep, cuspy inner profile. Here we report on a spectroscopic study of six clustersExpand
The cores of dwarf galaxy haloes
We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate the consequences ofExpand

Mass estimation in the outer regions of galaxy clusters
We present a technique for estimating the mass in the outskirts of galaxy clusters where the usual assumption of dynamical equilibrium is not valid. The method assumes that clusters form throughExpand
