PublicaciónThe galaxy-wide initial mass function of dwarf late-type to massive early-type galaxies
Observational studies are showing that the galaxy-wide stellar initial mass function (IMF) is top-heavy in galaxies with high star formation rates (SFRs)...

PublicaciónThe GeMS/GSAOI Galactic Globular Cluster Survey (G4CS). I. A Pilot Study of the Stellar Populations in NGC 2298 and NGC 3201
We present the first results from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) of the Milky Way globular clusters NGC 3201 and NGC 2298. Using the...

PublicaciónThe globular cluster kinematics and galaxy dark matter content of NGC 4649 (M60)
From observations with the GMOS multislit spectrograph on the Gemini North telescope, we have obtained spectra for 39 globular cluster (GC) candidates in the...

PublicaciónThe HST/ACS Coma Cluster Survey - X. Nuclear star clusters in low-mass early-type galaxies: scaling relations
We present scaling relations between structural properties of nuclear star clusters and their host galaxies for a sample of early-type dwarf galaxies observed...

PublicaciónThe HST/ACS Coma Cluster Survey. IV. Intergalactic Globular Clusters and the Massive Globular Cluster System at the Core of the Coma Galaxy Cluster
Intracluster stellar populations are a natural result of tidal interactions in galaxy clusters. Measuring these populations is difficult, but important for...

PublicaciónThe impact of galaxy harassment on the globular cluster systems of early-type cluster dwarf galaxies
The dynamics of globular cluster systems (GCSs) around galaxies are often used to assess the total enclosed mass, and even to constrain the dark matter...

PublicaciónThe intermediate age open cluster NGC 7044
A photometric analysis is conducted of the open cluster NGC 7044, on the basis of UBVR CCD observations of 896 stars in the cluster field. Reddening and...

PublicaciónThe Kinematics and Dynamics of the Globular Clusters and Planetary Nebulae of NGC 5128
A new kinematic and dynamic study of the halo of the giant elliptical galaxy NGC 5128 is presented. From a spectroscopically confirmed sample of 340 globular...
