| Abstract: |
We study the mass-metallicity relation of local galaxies
selected from a cross-identification of IRAS Point Source Catalogue Redshift
Survey (PSCz) and Sloan Digital Sky Survey Seventh Data Release (SDSS DR7). We
find that the mass-metallicity relation is not a function of infrared
luminosity. Infrared-selected spirals show a slightly higher metal enrichment,
compared to the M-Z relation defined by SDSS star-forming galaxies.
Whereas edge-on galaxies, interacting and merging systems follow the same
relation as the bulk of SDSS galaxies. |
