The star formation history of Seyfert 2 nuclei
We present a study of the stellar populations in the central ∼200 pc of a large and homogeneous sample comprising 79 nearby galaxies, most of which are Seyfert 2s. The star formation history of theseExpand

Alternative diagnostic diagrams and the 'forgotten' population of weak line galaxies in the SDSS
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 classicalExpand

A comprehensive classification of galaxies in the SDSS: How to tell true from fake AGN?
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 isExpand

Semi‐empirical analysis of Sloan Digital Sky Survey galaxies – III. How to distinguish AGN hosts
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 20000Expand

The CALIFA survey across the Hubble sequence: Spatially resolved stellar population properties in galaxies
Various different physical processes contribute to the star formation and stellar mass assembly histories of galaxies. One important approach to understanding the significance of these differentExpand

Star formation along the Hubble sequence: Radial structure of the star formation of CALIFA galaxies
The aim of this paper is to characterize the radial structure of the star formation rate (SFR) in galaxies in the nearby Universe as represented by the CALIFA survey. The sample under study containsExpand

A characteristic oxygen abundance gradient in galaxy disks unveiled with CALIFA
We present the largest and most homogeneous catalog of H ii regions and associations compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 galaxies observed by theExpand
