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…
A dark siren measurement of the Hubble constant using gravitational wave events from the first three LIGO/Virgo observing runs and DELVE
V. Alfradique, C. R. Bom, A. Palmese +17
The current and next observation seasons will detect hundreds of gravitational waves (GWs) from compact binary systems coalescence at cosmological distances. When combined with ind…
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…
