Comparing Globular Cluster System Properties with Host Galaxy Environment
Kate Hartman, William E. Harris, John P. Blakeslee +2
We present Hubble Space Telescope photometry in optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive el…
The Effect of Age and Stellar Model Choice on Globular Cluster Color-to-Metallicity Conversions
Kate Hartman, William E. Harris
The photometric colors of globular clusters (GCs) act as effective proxies for metallicity, since all normally used optical/IR color indices exhibit a nonlinear but monotonic relat…
The Space Infrared Interferometric Telescope (SPIRIT): High-resolution imaging and spectroscopy in the far-infrared
David Leisawitz, Charles Baker, Amy Barger +53
We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an ope…
SED Fitting of Globular Clusters in NGC 4874: Masses and Metallicities
Kate Hartman, William E. Harris, Jinoo Kim
In most nearby galaxies, photometry of the integrated light of their globular clusters (GCs) has been obtained in only two filters, yielding just a single color index. However, NGC…
Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397
Jessica M. Berkheimer, Rogier A. Windhorst, William E. Harris +27
We present a photometric analysis of globular clusters (GCs) in the massive galaxy cluster MACS J0416.1-2403 (z = 0.397) using deep JWST/NIRCam imaging from the PEARLS program. PSF…
