Characterizing the disruption of Böotes III: a missing link in the Galactic halo?
Jaclyn Jensen, Daniel A. Boyea, Alan W. McConnachie +14
The Böotes III (Boo3) dwarf galaxy has long been suspected of being the progenitor of Styx, a ~50°-long stellar stream that was simultaneously discovered in the same region of sky.…
The primordial nature of the C-19 stellar stream
Kim A. Venn, Zhen Yuan, Nicolas F. Martin +32
Stellar streams, remnants of compact star systems stretched out by the tidal forces of the Milky Way, offer a unique way to study stellar populations that formed billions of years…
No Observational Evidence for Dark Matter Nor a Large Metallicity Spread in the Extreme Milky Way Satellite Ursa Major III / UNIONS 1
William Cerny, Daisy Bissonette, Alexander P. Ji +9
The extremely-low-luminosity, compact Milky Way satellite Ursa Major III / UNIONS 1 (UMaIII/U1; ; pc) was found to have a substantial velocity d…
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,…
Deep in the Fields of the Andromeda Halo: Discovery of the Pegasus VII dwarf galaxy in UNIONS
Simon E. T. Smith, Alan W. McConnachie, Stephen Gwyn +8
We present the newly discovered dwarf galaxy Pegasus VII (Peg VII), a member of the M31 sub-group which has been uncovered in the photometric catalogs from the Ultraviolet Nea…
Quantifying the Detectability of Milky Way Satellites with Image Simulations: a Case Study with KiDS
Shiyang Zhang, Hendrik Hildebrandt, Ziang Yan +6
Ultra-faint dwarf galaxies, which can be detected as resolved satellite systems of the Milky Way, are critical to understanding galaxy formation, evolution, and the nature of dark…
New Kids in Town. Sextans~II: a new stellar system in the outskirts of the Milky Way
Massimiliano Gatto, Michele Bellazzini, Crescenzo Tortora +9
We report on the discovery of a significant and compact over-density of old and metal-poor stars in the KiDS survey (data release 4). The discovery is confirmed by deeper HSC-SSC d…
The discovery of the faintest known Milky Way satellite using UNIONS
Simon E. T. Smith, William Cerny, Christian R. Hayes +14
We present the discovery of Ursa Major III/UNIONS 1, the least luminous known satellite of the Milky Way, which is estimated to have an absolute V-band magnitude of $+2.2^{+0.4}_{-…
Ursa Major III/UNIONS 1: the darkest galaxy ever discovered?
Raphaël Errani, Julio F. Navarro, Simon E. T. Smith +1
The recently discovered stellar system Ursa Major III/UNIONS 1 (UMa3/U1) is the faintest known Milky Way satellite to date. With a stellar mass of and a…
Small-scale stellar haloes: detecting low surface brightness features in the outskirts of Milky Way dwarf satellites
Jaclyn Jensen, Christian R. Hayes, Federico Sestito +5
Dwarf galaxies are valuable laboratories for dynamical studies related to dark matter and galaxy evolution, yet it is currently unknown just how physically extended their stellar c…
Stars on the edge: Galactic tides and the outskirts of the Sculptor dwarf spheroidal
Federico Sestito, Joel Roediger, Julio F. Navarro +5
The formation of "stellar halos" in dwarf galaxies have been discussed in terms of early mergers or Galactic tides, although fluctuations in the gravitational potential due to stel…
Velocity-Coherent Substructure in TMC-1: Inflow and Fragmentation
Simon E. T. Smith, Rachel Friesen, Antoine Marchal +11
Filamentary structures have been found nearly ubiquitously in molecular clouds and yet their formation and evolution is still poorly understood. We examine a segment of Taurus Mole…
Discovery of a new Local Group Dwarf Galaxy Candidate in UNIONS: Boötes V
Simon E. T. Smith, Jaclyn Jensen, Joel Roediger +12
We present the discovery of Boötes V, a new ultra-faint dwarf galaxy candidate. This satellite is detected as a resolved overdensity of stars during an ongoing search for new Local…
