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…
HI-MaNGA: HI Followup for the MaNGA Survey
Karen L. Masters, David V. Stark, Zachary J. Pace +16
We present the HI-MaNGA programme of HI follow-up for the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey. MaNGA, which is part of the Fourth phase of the Sloan…
