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…
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…
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…
Limit on Supernova Emission in the Brightest Gamma-ray Burst, GRB 221009A
Manisha Shrestha, David J. Sand, Kate D. Alexander +30
We present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in th…
Surviving the Waves: evidence for a Dark Matter cusp in the tidally disrupting Small Magellanic Cloud
Michele De Leo, Justin I. Read, Noelia E. D. Noel +3
We use spectroscopic data for Red Giant Branch (RGB) stars in the Small Magellanic Cloud (SMC), together with proper motion data from \textit{Gaia} Early Data Release…
