The ringing Large Magellanic Cloud: evidence for a recent dwarf-dwarf collision
Slater J. Oden, Bethany Garver, Joshua Povick +2
Galaxy interactions are ubiquitous in the Universe and represent a primary pathway for galaxy growth. Close passages of dwarf galaxies can induce large-scale vertical oscillations…
[C/N] Ages and Extra-Mixing for [Fe/H] <- 0.5: Insights from the LMC and SMC
Yuxi Lu, John D. Roberts, Joshua T. Povick +4
The [C/N]-age relation has become a powerful tool for reconstructing the formation history of the Milky Way (MW), providing the largest age sample for field giant stars. However, a…
Overview of The SDSS-V Magellanic Genesis Survey
David L. Nidever, Danny Horta, Steven R. Majewski +14
The Sloan Digital Sky Survey-V (SDSS-V) Magellanic Genesis survey is a spectroscopic program designed to map the kinematic and chemical structure of the Magellanic Clouds using APO…
Warped & Hooked: Mapping the Magellanic Clouds in 3D using Red Clump stars
Slater J. Oden, David L. Nidever, Joshua Povick +18
The Large and Small Magellanic Clouds (LMC and SMC) are the Milky Way's nearest interacting galaxy pair, offering a unique laboratory for studying tidal effects on galactic disks.…
Stellar Birth Radii in the LMC: Insights into Chemodynamics, Radial Migration, and Star Formation Across the Disk
Yuxi Lu, Bethany Garver, David L. Nidever +4
The LMC and SMC are interacting dwarf galaxies that offer a valuable testbed for studying the effects of galactic mergers. We investigate the chemodynamic history of the LMC in the…
The Pristine Inner Galaxy Survey (PIGS) XI: Revealing the chemical evolution of the interacting Sagittarius dwarf galaxy
Sara Vitali, Alvaro Rojas-Arriagada, Paula Jofré +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is a satellite orbiting the Milky Way that has experienced multiple stripping events due to tidal interactions with our Galaxy. I…
What Does the Large Magellanic Cloud Look Like? It Depends on [M/H] and Age
Neige Frankel, Rene Andrae, Hans-Walter Rix +2
We offer a new way to look at the Large Magellanic Cloud through stellar mono-abundance and mono-age-mono-abundance maps. These maps are based on member stars wi…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. III. Abundance Gradients of the Small Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +10
We determine radial- and age-abundance gradients of the Small Magellanic Cloud (SMC) using spectra of 2,062 red giant branch (RGB) field stars observed by SDSS-IV / APOGEE-2S. With…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. II. Abundance Gradients of the Large Magellanic Cloud
Joshua T. Povick, David L. Nidever, Steven R. Majewski +10
We present the abundance gradients of the Large Magellanic Cloud (LMC) for 25 elemental abundance ratios and their respective temporal evolution as well as age-[X/Fe] trends using…
Exploring the Origin of the Distance Bimodality of Stars in the Periphery of the Small Magellanic Cloud with APOGEE and Gaia
Andres Almeida, Steven R. Majewski, David L. Nidever +12
The Magellanic Cloud system represents a unique laboratory for study of both interacting dwarf galaxies and the ongoing process of the formation of the Milky Way and its halo. We f…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. I. Calculating Individual Stellar Ages of RGB Stars in the Large Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +12
Stellar ages are critical for understanding the temporal evolution of a galaxy. We calculate the ages of over 6000 red giant branch stars in the Large Magellanic Cloud (LMC) observ…
APOGEE Chemical Abundance Patterns of the Massive Milky Way Satellites
Sten Hasselquist, Christian R. Hayes, Jianhui Lian +42
The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey has obtained high-resolution spectra for thousands of red giant stars distributed among the massi…
The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
David L. Nidever, Sten Hasselquist, Christian R. Hayes +28
We report the first APOGEE metallicities and alpha-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic C…
