The metallicity - redshift relations for emission-line SDSS galaxies: examination of the dependence on the star formation rate
L. S. Pilyugin, M. A. Lara-Lopez, E. K. Grebel +5
We analyse the oxygen abundance and specific star formation rates (sSFR) variations with redshift in star-forming SDSS galaxies of different masses. We find that the maximum value…
Abundance determination from global emission-line SDSS spectra: exploring objects with high N/O ratios
L. S. Pilyugin, J. M. Vilchez, L. Mattsson +1
We have compared the oxygen and nitrogen abundances derived from global emission-line SDSS spectra of galaxies using (1) the Te method and (2) two recent strong line calibrations:…
SDSS galaxies with double-peaked emission lines: double starbursts or AGNs?
L. S. Pilyugin, I. A. Zinchenko, B. Cedres +4
With the aim of investigating galaxies with two strong simultaneous starbursts, we have extracted a sample of galaxies with double-peaked emission lines in their global spectra fro…
