Solo dwarfs III: Exploring the orbital origins of isolated Local Group galaxies with Gaia Data Release 2
Alan W. McConnachie, Clare R. Higgs, Guillaume F. Thomas +4
We measure systemic proper motions for distant dwarf galaxies in the Local Group and investigate if these isolated galaxies have ever had an interaction with the Milky Way or M31.…
The hidden past of M92: Detection and characterization of a newly formed 17° long stellar stream using the Canada-France Imaging Survey
Guillaume F. Thomas, Jaclyn Jensen, Alan McConnachie +17
We present an analysis of the structure, kinematics and orbit of a newly found stellar stream emanating from the globular cluster M92 (NGC 6341). This stream was discovered in an i…
White Dwarfs in the Era of the LSST and its Synergies with Space-Based Missions
Nicholas J. Fantin, Patrick Côté, Alan McConnachie
With the imminent start of the Legacy Survey for Space and Time (LSST) on the Vera C. Rubin Observatory, and several new space telescopes expected to begin operations later in this…
The Next Generation Virgo Cluster Survey. XXXIV. Ultra-Compact Dwarf (UCD) Galaxies in the Virgo Cluster
Chengze Liu, Patrick Côté, Eric W. Peng +26
We present a study of ultra compact dwarf (UCD) galaxies in the Virgo cluster based mainly on imaging from the Next Generation Virgo Cluster Survey (NGVS). Using 100 deg$^{2}…
The Next Generation Virgo Cluster Survey (NGVS). XXX. Ultra-Diffuse Galaxies and their Globular Cluster Systems
Sungsoon Lim, Patrick Côté, Eric W. Peng +14
We present a study of ultra-diffuse galaxies (UDGs) in the Virgo Cluster based on deep imaging from the Next Generation Virgo Cluster Survey (NGVS). Applying a new definition for t…
The Next Generation Fornax Survey (NGFS): VII. A MUSE view of the nuclear star clusters in Fornax dwarf galaxies
Evelyn J. Johnston, Thomas H. Puzia, Giuseppe D'Ago +16
Clues to the formation and evolution of Nuclear Star Clusters (NSCs) lie in their stellar populations. However, these structures are often very faint compared to their host galaxy,…
Multiple Chemodynamic Stellar Populations of the Ursa Minor Dwarf Spheroidal Galaxy
Andrew B. Pace, Manoj Kaplinghat, Evan Kirby +6
We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data w…
