Updated proper motions for Local Group dwarf galaxies using Gaia Early Data Release 3
Alan W. McConnachie, Kim A. Venn
Updated systemic proper motion estimates for 58 Milky Way satellite galaxies, based on Gaia Early Data Release 3 (EDR3), are provided. This sample is identical to that studied by M…
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 proper motion of Andromeda from Gaia eDR3: confirming a nearly radial orbit
J. -B. Salomon, R. Ibata, C. Reylé +4
We present an analysis of the proper motion of the Andromeda galaxy (M31), based on the Early Third Data Release of the Gaia mission. We use the Gaia photometry to select young blu…
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…
Observing the stellar halo of Andromeda in cosmological simulations: the Auriga2PAndAS pipeline
Guillaume F. Thomas, Nicolas F. Martin, Azadeh Fattahi +10
We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of 6 galaxies from the Auriga simu…
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…
