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…
Constraining Photoionization Models With a Reprojected Optical Diagnostic Diagram
Xihan Ji, Renbin Yan
Optical diagnostic diagrams are powerful tools to separate different ionizing sources in galaxies. However, the model-constraining power of the most widely-used diagrams is very li…
Swift/UVOT+MaNGA (SwiM) Value-added Catalog
M. Molina, N. Ajgaonkar, R. Yan +5
We introduce the Swift/UVOT+MaNGA (SwiM) value added catalog, which comprises 150 galaxies that have both SDSS/MaNGA integral field spectroscopy and archival Swift/UVOT near-UV (NU…
Stellar parameters for the First Release of the MaStar Library: An Empirical Approach
Yan-Ping Chen, Renbin Yan, Claudia Maraston +10
We report the stellar atmospheric parameters for 7503 spectra contained in the first release of the MaNGA stellar library (MaStar) in SDSS DR15. The first release of MaStar contain…
Upper boundaries of AGN regions in optical diagnostic diagrams
Xihan Ji, Renbin Yan, Rogerio Riffel +2
The distribution of galaxies in optical diagnostic diagrams can provide information about their physical parameters when compared with ionization models under proper assumptions. B…
