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… 

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 structure

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 major

Galactic Dark Matter Halos and Globular Cluster Populations. III. Extension to Extreme Environments

The total mass in the globular cluster (GC) system of a galaxy is empirically a near-constant fraction of the total mass of the galaxy across a range of 105 in galaxy mass. This trend is radically

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 ( log M star / M ⊙ ≳ 11.3 ) early-type galaxies and its dependence on galactic properties and host halo mass with

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 at

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)

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 branches

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 cluster

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-out

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 the
