Semi‐empirical analysis of Sloan Digital Sky Survey galaxies – I. Spectral synthesis method
- R. Fernandes, A. Mateus, L. Sodr'e, G. Stasi'nska, J. Gomes
- Physics
- 1 April 2005
The study of stellar populations in galaxies is entering a new era with the availability of large and high-quality data bases of both observed galactic spectra and state-of-the-art evolutionary… Expand
The chemical composition of metal-poor emission-line galaxies in the Data Release 3 of the Sloan Digital Sky Survey
- Y. Izotov, G. Stasi'nska, +12 authors Usa
- Physics
- 22 November 2005
We have re-evaluated empirical expressions for the abundance determination of N, O, Ne, S, Cl, Ar and Fe taking into account the latest atomic data and constructing an appropriate grid of… Expand
Alternative diagnostic diagrams and the 'forgotten' population of weak line galaxies in the SDSS
- R. Fernandes, G. Stasi'nska, +9 authors Usp
- Physics
- 9 December 2009
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, since classical… Expand
A comprehensive classification of galaxies in the SDSS: How to tell true from fake AGN?
- R. Fernandes, G. Stasi'nska, +5 authors France
- Physics
- 20 December 2010
We use the W Hα versus [NII]/Hα (WHAN) diagram introduced by us in previous work to provide a comprehensive emission-line classification of Sloan Digital Sky Survey galaxies. This classification is… Expand
Semi‐empirical analysis of Sloan Digital Sky Survey galaxies – III. How to distinguish AGN hosts
- G. Stasi'nska, R. Fernandes, A. Mateus, L. Sodr'e, N. V. Asari
- Physics
- 29 June 2006
This paper considers the techniques to distinguish normal star-forming (NSF) galaxies and active galactic nuclei (AGNs) hosts using optical spectra. The observational data base is a set of 20000… Expand
A VLT study of metal-rich extragalactic H II regions - I. Observations and empirical abundances
- F. Bresolin, D. Schaerer, R. Delgado, G. Stasi'nska
- Physics
- 3 June 2005
We have obtained spectroscopic observations from 3600 Ato 9200 Awith FORS at the Very Large Telescope for approximately 70 H iiregions located in the spiral galaxies NGC 1232, NGC 1365, NGC 2903, NGC… Expand
Biases in abundance derivations for metal-rich nebulae
- G. Stasi'nska
- Physics
- 26 January 2005
Using ab-initio photoionization models of giant H ii regions, we test methods for abundance determinations based on a direct measurement of the electron temperature, now possible even for moderate… Expand
The history of star-forming galaxies in the Sloan Digital Sky Survey
- N. V. Asari, R. Fernandes, +14 authors Usp
- Physics
- 24 July 2007
This paper, the sixth in the Semi-Empirical Analysis of Galaxies series, studies the evolution of 82 302 star-forming (SF) galaxies from the Sloan Digital Sky Survey. Star formation histories (SFHs)… Expand
The Canada-France Redshift Survey XII: Nature of emission-line field galaxy population up to z = 0.3
- L. Tresse, C. Rola, +4 authors D. Crampton
- Physics
- 4 April 1996
We present a spectroscopic study of the 138 field galaxies to a redshift z = 0.3 from the I-selected Canada-France Redshift Survey. 117 (85%) spectra exhibit at least H� in emission, the remaining 21… Expand
H II GALAXIES VERSUS PHOTOIONIZATION MODELS FOR EVOLVING STARBURSTS
- G. Stasi'nska, C. Leitherer
- Physics
- 1 December 1996
We have constructed a grid of models representing an H II region produced by an evolving starburst embedded in a gas cloud of the same metallicity. The models were produced with the spectral energy… Expand
