The Milky Way tomography with APOGEE: intrinsic density distribution and structure of mono-abundance populations
Jianhui Lian, Gail Zasowski, Ted Mackereth +11
The spatial distribution of mono-abundance populations (MAPs, selected in [Fe/H] and [Mg/Fe]) reflect the chemical and structural evolution in a galaxy and impose strong constraint…
Quantifying radial migration in the Milky Way: Inefficient over short timescales but essential to the very outer disc beyond ~15 kpc
Jianhui Lian, Gail Zasowski, Sten Hasselquist +10
Stellar radial migration plays an important role in reshaping a galaxy's structure and the radial distribution of stellar population properties. In this work, we revisit reported o…
SDSS-IV MaNGA: drivers of stellar metallicity in nearby galaxies
Justus Neumann, Daniel Thomas, Claudia Maraston +12
The distribution of stellar metallicities within and across galaxies is an excellent relic of the chemical evolution across cosmic time. We present a detailed analysis of spatially…
SDSS-IV MaNGA: the physical origin of off-galaxy H blobs in the local Universe
Xihan Ji, Cheng Li, Renbin Yan +9
H blobs are off-galaxy emission-line regions with weak or no optical counterparts. They are mostly visible in H line, appearing as concentrated blobs. Such unusual objects ha…
SDSS-IV MaNGA: galaxy gas-phase metallicity gradients vary across the mass-size plane
Nicholas F. Boardman, Gail Zasowski, Jeffrey A. Newman +5
Gas-phase abundances and abundance gradients provide much information on past stellar generations, and are powerful probes of how galaxies evolve. Gas abundance gradients in galaxi…
The chemical properties of the Milky Way's on-bar and off-bar regions: evidence for inhomogeneous star formation history in the bulge
Jianhui Lian, Gail Zasowski, Sten Hasselquist +7
Numerous studies of integrated starlight, stellar counts, and kinematics have confirmed that the Milky Way is a barred galaxy. However, far fewer studies have investigated the bar'…
