Discovery, Characterization, and Potential Origins of a Stream in the Stellar Halo of Nearby LMC-Mass Galaxy NGC 55
Benjamin N. Velguth, Burçin Mutlu-Pakdil, Erik Tollerud +33
We present a previously undetected stellar stream in the halo of the LMC-mass dwarf galaxy NGC 55 (2 Mpc), as part of an ongoing effort to characterize the stellar halos of LMC/SMC…
A Pride of Satellites in the Constellation Leo? Discovery of the Leo VI Milky Way Satellite Galaxy with DELVE Early Data Release 3
C. Y. Tan, W. Cerny, A. Drlica-Wagner +32
We report the discovery and spectroscopic confirmation of an ultra-faint Milky Way (MW) satellite in the constellation of Leo. This system was discovered as a spatial overdensity o…
Unveiling the purely young star formation history of the SMC's northeastern shell from colour-magnitude diagram fitting
Joanna D. Sakowska, Noelia E. D. Noël, Tomás Ruiz-Lara +12
We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC). We use the Survey of…
EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies
Emily I. Gray, Justin I. Read, Ethan Taylor +8
Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to 4…
Reading Between the (Spectral) Lines: Magellan/IMACS spectroscopy of the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I
M. E. Heiger, T. S. Li, A. B. Pace +17
We present a spectroscopic analysis of Eridanus IV (Eri IV) and Centaurus I (Cen I), two ultra-faint dwarf galaxies of the Milky Way. Using IMACS/Magellan spectroscopy, we identify…
EDGE: The direct link between mass growth history and the extended stellar haloes of the faintest dwarf galaxies
Alex Goater, Justin I. Read, Noelia E. D. Noël +9
Ultra-faint dwarf galaxies (UFDs) are commonly found in close proximity to the Milky Way and other massive spiral galaxies. As such, their projected stellar ellipticity and extende…
