It's a matter of time: Empirical Constraints on Supernova Yields and Delay Times from Dwarf Spheroidal Galaxies
Mairéad E. Heiger, Alexander P. Ji, Joshua S. Speagle +6
The chemical abundances of a stellar population encode information about nucleosynthesis and its astrophysical sites, but this information is confounded by the specific star format…
Not-so-heavy metal(s): Chemical Abundances in the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I
Mairéad E Heiger, Alexander P Ji, Ting S Li +18
We present detailed chemical abundances of the brightest star in each of the ultra-faint dwarf galaxies Eridanus IV and Centaurus I using high-resolution Magellan/MIKE spectroscopy…
The Cocytos Stream: A Disrupted Globular Cluster from our Last Major Merger?
Christian Aganze, Vedant Chandra, Risa H. Wechsler +47
The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey (w…
Deep Photometric Observations of Ultra-Faint Milky Way Satellites Centaurus I and Eridanus IV
Quinn O. Casey, Burçin Mutlu-Pakdil, David J. Sand +19
We present deep MagellanMegacam imaging of Centaurus I (Cen I) and Eridanus IV (Eri IV), two recently discovered Milky Way ultra-faint satellites. Our data reach magni…
