Journal ArticleDOI
Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies
N. Vale Asari,N. Vale Asari,Guilherme S. Couto,Guilherme S. Couto,R. Cid Fernandes,Grazyna Stasinska,A. L. de Amorim,D. Ruschel-Dutra,A. Werle,A. Werle,T Z Florido +10 more
TL;DR: In this article, the authors investigated the impact of diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies using spectra from the Mapping Nearby Galaxies at APO (MaNGA).
Journal ArticleDOI
The evolution of the mass-metallicity relation in SDSS galaxies uncovered by astropaleontology
N. Vale Asari,Grazyna Stasinska,R. Cid Fernandes,J. M. Gomes,M. Schlickmann,Abílio Mateus,William Schoenell +6 more
TL;DR: 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 estimated with the spectral synthesis code STARLIGHT, was obtained in this paper.
Journal ArticleDOI
An analysis of the composite stellar population in M32
TL;DR: In this paper, the authors obtained long-slit spectra of the galaxy M32 with the GMOS spectrograph at the GEMINI North telescope, and analyzed the integrated spectra by means of full spectral fitting in order to extract the mixture of stellar populations that best represents its composite nature.
Journal ArticleDOI
The Obscuring Starburst of NGC 6221 and Implications for the Hard X-Ray Background
N. A. Levenson,R. Cid Fernandes,K. A. Weaver,K. A. Weaver,Timothy M. Heckman,Thaisa Storchi-Bergmann +5 more
TL;DR: In this article, the authors presented NGC 6221 as a case study of X-ray-loud composite galaxies, which appear similar to starbursts at optical wavelengths and resemble traditional active galactic nuclei in X-rays.
Journal ArticleDOI
Qualitative interpretation of galaxy spectra
J. Sánchez Almeida,J. Sánchez Almeida,Roberto Terlevich,Roberto Terlevich,Elena Terlevich,R. Cid Fernandes,A. B. Morales-Luis,A. B. Morales-Luis +7 more
TL;DR: In this article, a step-by-step guide to qualitative interpretation of galaxy spectra is described, and a description of the properties of the gas and the stars that characterize the ASK classes, from those corresponding to passively evolving galaxies, to HII galaxies undergoing a galaxywide starburst.
