The Ages of Globular Clusters in NGC 4365 Revisited with Deep HST Observations
Arunav Kundu, Stephen E. Zepf, Maren Hempel +6
We present new Hubble Space Telescope (HST)-NIC3, near-infrared H-band photometry of globular clusters (GC) around NGC 4365 and NGC 1399 in combination with archival HST-WCPC2 and…
Modeling the dynamical evolution of the M87 globular cluster system
E. Vesperini, S. E. Zepf, A. Kundu +1
We study the dynamical evolution of the M87 globular cluster system (GCS) with a number of numerical simulations. We explore a range of different initial conditions for the GCS mas…
Globular Cluster Formation
Keith M. Ashman
The discovery of young globular clusters in merging galaxies and other environments provides an opportunity to study directly the process of globular cluster formation. Empirically…
A Comparative Study of Globular Cluster Systems in UGC 9799 and NGC 1129
Myung Gyoon Lee, Eunhyeuk Kim, Doug Geisler +2
We present a preliminary analysis of HST-WFPC2 observations of globular cluster systems in the two brightest galaxies, UGC 9799 (cD) and NGC 1129 (non-cD), located in the center of…
Some Constraints on The Formation of Globular Clusters
Keith M. Ashman, Stephen E. Zepf
We explore the constraints on globular cluster formation provided by the observed conditions in starbursts where globulars are currently forming, and by the observed properties of…
Dynamical Constraints on the Formation of NGC 4472 and Its Globular Clusters
Stephen E. Zepf, Michael A. Beasley, Terry J. Bridges +4
We present new radial velocities for 87 globular clusters around the elliptical galaxy NGC 4472, and combine these with our previously published data to create a data set of veloci…
