Outside-In Evolution with a Twist: Metallicity Gradients and Asymmetries in the SMC
M. Navabi, R. Carrera, N. E. D. Noël +1
Taking advantage of the near-infrared calcium triplet lines, we determine metallicities for a sample of more than 3,500 red giant stars in the field of the Small Magellanic Cloud (…
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 NGC3109 Satellite System: The First Systematic Resolved Search for Dwarf Galaxies Around a SMC-mass Host
Amandine Doliva-Dolinsky, Burçin Mutlu-Pakdil, Denija Crnojević +38
We report the results of the deepest search to date for dwarf galaxies around NGC3109, a barred spiral galaxy with a mass similar to that of the Small Magellanic Cloud (SMC), using…
DELVE-DEEP Survey: The Faint Satellite System of NGC 55
Jonah Medoff, Burçin Mutlu-Pakdil, Jeffrey L. Carlin +24
We report the first comprehensive census of the satellite dwarf galaxies around NGC 55 ( Mpc) as a part of the DECam Local Volume Exploration DEEP (DELVE-DEEP) survey. NGC 55…
The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy
Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg +26
The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photom…
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…
