The solitary star cluster of the Andromeda XXV dwarf spheroidal
Chiara Crociati, Annette M. N. Ferguson, Gracie McGill +6
We present Hubble Space Telescope Advanced Camera for Surveys observations of Gep I, a globular cluster (GC) candidate in the low-mass ()…
Revisiting the enigmatic sixth star cluster in the Fornax dwarf spheroidal galaxy
Chiara Crociati, Annette M. N. Ferguson, Raffaele Pascale +7
The Fornax dwarf spheroidal (dSph) galaxy is one of only two Local Group dSphs that host a population of globular star clusters (GCs), the present-day properties of which have ofte…
Disruption of a Giant: Spectroscopic Identification of Members in the Periphery and Tidal Tails of Centauri
P. B. Kuzma, A. M. N. Ferguson, A. L. Varri +1
Centauri ( Cen, NGC\,5139) is one of the most enigmatic globular clusters in the Milky Way, with the recent detection of tidal tails adding further to its complexity. We rep…
Galactic Archaeology with the Subaru `Ōnohi`ula Prime Focus Spectrograph Strategic Program
Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +48
The recently commissioned Subaru `Ōnohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strateg…
The case of NGC 5824, a cluster possibly embedded in a dark matter halo
Paula B. Díaz, Berenice Muruaga, Ricardo R. Muñoz +3
The globular cluster NGC 5824 exhibits a diffuse stellar envelope that extends beyond its nominal King tidal radius and symmetrically surrounds the cluster. The origin of these sta…
Subaru/HSC NB395 view of NGC 5466: metallicity, mass function, and the nature of its tidal stream
Itsuki Ogami, Miho N. Ishigaki, Pete B. Kuzma +6
We present a deep photometric study of the globular cluster NGC 5466 and its tidal stream using Subaru/Hyper Suprime-Cam (HSC) imaging with the metallicity-sensitive narrowband fil…
