Journal ArticleDOI
Alternative diagnostic diagrams and the 'forgotten' population of weak line galaxies in the SDSS
R. Cid Fernandes,Grazyna Stasinska,M. Schlickmann,Abílio Mateus,N. Vale Asari,N. Vale Asari,William Schoenell,Laerte Sodré +7 more
TL;DR: In this article, the authors proposed to use the BPT diagram for galaxy classification and showed that the W Hα versus [N II]/Hα diagram can be applied to the largest sample of galaxies without loss of discriminating power between Seyferts and LINERs.
Journal ArticleDOI
Alternative diagnostic diagrams and the "forgotten" population of weak line galaxies in the SDSS
R. Cid Fernandes,Grazyna Stasinska,M. Schlickmann,Abílio Mateus,N. Vale Asari,William Schoenell,Laerte Sodré +6 more
TL;DR: In this paper, the authors propose to use the SDSS DR7 data set for the classification of weak line galaxies (WLGs) by transposing the usual divisory lines between Star Forming (SF) and AGN hosts, and between Seyferts and LINERs to diagrams that are more economical in terms of line quality requirements.
Journal ArticleDOI
The history of star-forming galaxies in the Sloan Digital Sky Survey
Natalia Vale Asari,R. Cid Fernandes,Grazyna Stasinska,J. P. Torres-Papaqui,J. P. Torres-Papaqui,Abílio Mateus,Laerte Sodré,William Schoenell,Jean Michel Gomes +8 more
TL;DR: In this article, the authors studied the evolution of 82 302 star-forming galaxies from the Sloan Digital Sky Survey and derived Star Formation Histories (SFHs) from detailed spectral fits obtained with the publicly available spectral synthesis code STARLIGHT.
Journal ArticleDOI
Semi-empirical analysis of Sloan Digital Sky Survey galaxies – II. The bimodality of the galaxy population revisited
Abílio Mateus,Laerte Sodré,Roberto Cid Fernandes,Grazyna Stasinska,William Schoenell,Jean Michel Gomes +5 more
TL;DR: In this paper, the bimodal distribution of the galaxy population commonly seen in the local universe was revisited in terms of spectral synthesis products, such as mean stellar ages and stellar masses.
Journal ArticleDOI

TL;DR: In this paper, the authors presented multicolor photometry and photometric redshifts for approximately438,000 galaxies, detected in synthetic F814W images, complete down to a magnitude I�24.5AB with the ColorPro software.
