Stellar streams around dwarf galaxies are observationally rare in the local Universe
Joanna D. Sakowska, David Martíınez-Delgado, Sarah Pearson +6
The frequency and properties of stellar streams around dwarf galaxies remain observationally under-explored. Building a statistically significant sample is challenging because dwar…
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…
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…
DELVE 6: An Ancient, Ultra-Faint Star Cluster on the Outskirts of the Magellanic Clouds
W. Cerny, A. Drlica-Wagner, T. S. Li +23
We present the discovery of DELVE 6, an ultra-faint stellar system identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Based on a maximum-li…
Star Formation History of the Small Magellanic Cloud: the shell substructure
Joanna D. Sakowska, Noelia E. D. Noël, Tomás Ruiz-Lara +1
We present the spatially resolved star formation history (SFH) of a shell-like structure located in the northeastern Small Magellanic Cloud (SMC). We quantitatively obtain the SFH…
