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 …

We use the W Hα versus [N ii]/Hα (WHAN) diagram introduced by us in previous work to
provide a comprehensive emission-line classification of Sloan Digital Sky Survey 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 …

We present initial results of an ESO-VLT large programme (AMAZE) aimed at determining
the evolution of the mass-metallicity relation at z> 3 by means of deep near-IR spectroscopy …

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 …

We present intermediate-resolution optical spectrophotometry of 65 galaxies obtained in
support of the Spitzer Infrared Nearby Galaxies Survey (SINGS). For each galaxy we obtain …

Aims. Fossil record methods based on spectral synthesis techniques have matured during
the past decade, and their application to integrated galaxy spectra has fostered substantial …

We investigate how the typical dust extinction of Hα luminosity from a star-forming galaxy
depends upon star formation rate (SFR), metallicity and stellar mass independently, using a …

The spatially resolved stellar population content of today's galaxies holds important
information for understanding the different processes that contribute to the star formation and …

The classification of galaxies as star forming or active is generally done in the ([O iii]/Hβ,[N
ii]/Hα) plane. The Sloan Digital Sky Survey (SDSS) has revealed that, in this plane, the …
