SDSS-IV MaNGA: Modeling the Spectral Line Spread Function to Sub-Percent Accuracy
David R. Law, Kyle B. Westfall, Matthew A. Bershady +10
The SDSS-IV Mapping Nearby Galaxies at APO (MaNGA) program has been operating from 2014-2020, and has now observed a sample of 9,269 galaxies in the low redshift universe (z ~ 0.05…
SDSS-IV MaNGA: Refining Strong Line Diagnostic Classifications Using Spatially Resolved Gas Dynamics
David R. Law, Xihan Ji, Francesco Belfiore +8
We use the statistical power of the MaNGA integral-field spectroscopic galaxy survey to improve the definition of strong line diagnostic boundaries used to classify gas ionization…
SDSS-IV MaNGA: The Nature of an Off-galaxy H Blob -- A Multi-wavelength View of Offset Cooling in a Merging Galaxy Group
Hsi-An Pan, Lihwai Lin, Bau-Ching Hsieh +20
Galaxies in dense environments, such as groups and clusters, experience various processes by which galaxies gain and lose gas. Using data from the SDSS-IV MaNGA survey, we previous…
Stellar Population Synthesis with Distinct Kinematics: Multi-Age Asymmetric Drift in SDSS-IV MaNGA Galaxies
Shravan Shetty, Matthew A. Bershady, Kyle B. Westfall +5
We present the first asymmetric drift (AD) measurements for unresolved stellar populations of different characteristic ages above and below 1.5 Gyr. These measurements sample the a…
Comparison of stellar populations in simulated and real post-starburst galaxies in MaNGA
Yirui Zheng, Vivienne Wild, Natalia Lahén +4
Recent integral field spectroscopic (IFS) surveys have revealed radial gradients in the optical spectral indices of post-starburst galaxies, which can be used to constrain their fo…
