We study environmental quenching using the spatial distribution of current star-formation and stellar population ages with the full SAMI Galaxy Survey. By using a star-formation concentration index [C-index, defined as log10(r_{50,Halpha}/r_{50,cont}

SDSS-IV MaNGA: Variations in the N/O -- O/H relation bias metallicity gradient measurements

Autor: Schaefer, Adam L., Tremonti, Christy, Belfiore, Francesco, Pace, Zachary, Bershady, Matthew A., Andrews, Brett H., Drory, Niv

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 diagnostics. We find radial variations in N/O at fixed O/H which correlate

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 40000 star formation histories (SFHs). Using this library, we provide es
