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.…
Charting the Galactic acceleration field I. A search for stellar streams with Gaia DR2 and EDR3 with follow-up from ESPaDOnS and UVES
Rodrigo Ibata, Khyati Malhan, Nicolas Martin +10
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spect…
The Pristine survey -- XII: Gemini-GRACES chemo-dynamical study of newly discovered extremely metal-poor stars in the Galaxy
Collin L. Kielty, Kim A. Venn, Federico Sestito +16
High-resolution optical spectra of 30 metal-poor stars selected from the \Pristine\ survey are presented, based on observations taken with the Gemini Observatory GRACES spectrograp…
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…
The Pristine Inner Galaxy Survey (PIGS) II: Uncovering the most metal-poor populations in the inner Milky Way
Anke Arentsen, Else Starkenburg, Nicolas F. Martin +19
Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest meta…
