SDSS-IV MaNGA: Variations in the N/O -- O/H relation bias metallicity gradient measurements
Adam L. Schaefer, Christy Tremonti, Francesco Belfiore +4
In this paper we use strong line calibrations of N/O and O/H in MaNGA spaxel data to explore the systematics introduced by variations in N/O on various strong-line metallicity diag…
SDSS-IV MaNGA: Evidence for enriched accretion onto satellite galaxies in dense environments
Adam L. Schaefer, Christy Tremonti, Zachary Pace +9
We investigate the environmental dependence of the local gas-phase metallicity in a sample of star-forming galaxies from the MaNGA survey. Satellite galaxies with stellar masses in…
Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper II: Applications of PCA-based stellar mass estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
A galaxy's stellar mass is one of its most fundamental properties, but it remains challenging to measure reliably. With the advent of very large optical spectroscopic surveys, effi…
Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper I: PCA spectral fitting & stellar mass-to-light ratio estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
We present a method of fitting optical spectra of galaxies using a basis set of six vectors obtained from principal component analysis (PCA) of a library of synthetic spectra of 40…
SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies
Amelia Fraser-McKelvie, Michael Merrifield, Alfonso Aragón-Salamanca +11
Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so far however, limitin…
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Emission-Line Modeling
Francesco Belfiore, Kyle B. Westfall, Adam Schaefer +12
SDSS-IV MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is the largest integral-field spectroscopy survey to date, aiming to observe a statistically representative samp…
