Alternative diagnostic diagrams and the "forgotten" population of weak line galaxies in the SDSS
R. Cid Fernandes, G. Stasinska, M. S. Schlickmann +5
A numerous population of weak line galaxies (WLGs) is often left out of statistical studies on emission line galaxies (ELGs) due to the absence of an adequate classification scheme…
Emission line taxonomy and the nature of AGN-looking galaxies in the SDSS
Roberto Cid Fernandes, Grazyna Stasinska, Natalia Vale Asari +3
Massive spectroscopic surveys like the SDSS have revolutionized the way we study AGN and their relations to the galaxies they live in. A first step in any such study is to define s…
What stellar populations can tell us about the evolution of the mass-metallicity relation in SDSS galaxies
N. Vale Asari, G. Stasinska, R. Cid Fernandes +4
During the last three decades, many papers have reported the existence of a luminosity-metallicity or mass-metallicity (M-Z) relation for all kinds of galaxies: The more massive ga…
The evolution of the mass-metallicity relation in SDSS galaxies uncovered by astropaleontology
N. Vale Asari, G. Stasinska, R. Cid Fernandes +4
We have obtained the mass-metallicity (M-Z) relation at different lookback times for the same set of galaxies from the Sloan Digital Sky Survey, using the stellar metallicities est…
Star-powered LINERs in the Sloan Digital Sky Survey
N. Vale Asari, G. Stasinska, R. Cid Fernandes +5
Galaxies are usually classified as star forming or active by using diagnostic diagrams, such as [N II]/Halpha vs. [O III]/Hbeta. Active galaxies are further classified into Seyfert…
The starburst-AGN disconnection
R. Cid Fernandes, M. Schlickmann, G. Stasinska +5
Optical studies of starbursts, AGN and their connections usually leave out galaxies whose emission lines are too weak to warrant reliable measurement and classification. Yet, weak…
