VizieR Online Data Catalog: N/O and Ne/O ratios of SDSS dwarf galaxies (Douglass+, 2018)
Abstract
We look to expand on the work by Douglass & Vogeley (2017, J/ApJ/834/186 and 2017, J/ApJ/837/42) by substantially increasing their sample size of dwarf galaxies. We use emission-line flux data from the MPA-JHU value-added catalog, which is based on the SDSS DR7 sample of galaxies; as described at http://www.sdss.org/dr12/spectro/galaxy_mpajhu/ and in Tremonti+ (2004ApJ...613..898T).
