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…
Constructing a Pristine View of Extended Globular Cluster Structure
Pete B. Kuzma, Miho N. Ishigaki, Takanobu Kirihara +1
Globular Clusters (GCs) displaying extended structures are becoming increasingly ubiquitous in the Milky Way (MW). Despite their low surface brightness, which makes disentangling t…
UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
Kinematics of metallicity populations in Omega Centauri using Gaia Focused Product Release and Hubble Space Telescope
Nagaraj Vernekar, Sara Lucatello, Pete Kuzma +1
Context. Omega Cen is the largest known globular cluster in the Milky Way. It is also quite a complex object with a large metallicity spread and multiple stellar populations. Despi…
A Pristine View of Galactic Globular Clusters and their Peripheries: Omega Centauri
P. B. Kuzma, M. N. Ishigaki
The central regions of the globular cluster Omega Centauri ( Cen) have been extensively studied, but its outer regions and tidal structure have been less so. Gaia's astrometry u…
Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data
M. Libralato, L. R. Bedin, M. Griggio +175
The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
Euclid: Early Release Observations -- Unveiling the morphology of two Milky Way globular clusters out to their periphery
D. Massari, E. Dalessandro, D. Erkal +158
As part of the Euclid Early Release Observations (ERO) programme, we analyse deep, wide-field imaging from the VIS and NISP instruments of two Milky Way globular clusters (GCs), na…
Euclid: Early Release Observations -- Programme overview and pipeline for compact- and diffuse-emission photometry
J. -C. Cuillandre, E. Bertin, M. Bolzonella +260
The Euclid ERO showcase Euclid's capabilities in advance of its main mission, targeting 17 astronomical objects, from galaxy clusters, nearby galaxies, globular clusters, to star-f…
Dynamics in the outskirts of four Milky Way globular clusters: it's the tides that dominate
