M31 Globular Clusters in the HST Archive: II. Structural Parameters
P. Barmby, S. Holland, J. P. Huchra
We analyze the structural parameters of the largest-available sample of spatially resolved extragalactic globular clusters. The images of M31 GCs were found in a search of HST arch…
M31 Globular Clusters in the HST Archive: I. Cluster Detection and Completeness
P. Barmby, J. P. Huchra
Globular clusters at the distance of M31 have apparent angular sizes of a few arcseconds. While many M31 GCs have been detected and studied from ground-based images, the high spati…
The M31 Globular Cluster Luminosity Function
P. Barmby, J. P. Huchra, J. P. Brodie
We combine our compilation of photometry of M31 globular cluster and probable cluster candidates with new near-infrared photometry for 30 objects. Using these data we determine the…
The Elliptical Galaxy formerly known as the Local Group: Merging the Globular Cluster Systems
Duncan A. Forbes, Karen L. Masters, Dante Minniti +1
Prompted by a new catalogue of M31 globular clusters, we have collected together individual metallicity values for globular clusters in the Local Group. Although we briefly describ…
Testing population synthesis models with globular cluster colors
Pauline Barmby, John P. Huchra
We have measured an extensive set of UBVRIJHK colors for M31 globular clusters [Barmby et al. 2000]. We compare the predicted simple stellar population colors of three population s…
Kinematics of the Hercules Supercluster
Pauline Barmby, John P. Huchra
The Hercules Supercluster consists of the Abell clusters 2147, 2151, and 2152. Previous studies of the kinematics have been confounded by the difficulty of correctly assigning gala…
