    The Hα galaxy survey. I. The galaxy sample, Hα narrow-band observations and star formation parameters for 334 galaxies
    We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe...
  • Publication
    The Hα Galaxy Survey. II. Extinction and [NII] corrections to Hα fluxes
    We study the two main corrections generally applied to narrow-band Hα fluxes from galaxies in order to convert them to star formation rates, namely for [NII]...
  • Publication
    The Hα Galaxy survey. IV. Star formation in the local Universe
    Aims: We present an analysis of the star formation properties of field galaxies within the local volume out to a recession velocity limit of 3000 km s-1...
  • Publication
    The Hα galaxy survey. VII. The spatial distribution of star formation within disks and bulges
    Aims: We analyse the current build-up of stellar mass within the disks and bulges of nearby galaxies through a comparison of the spatial distributions of...
  • Publication
    The Hα Galaxy Survey. VIII. Close Companions and Interactions, and the Definition of Starbursts
    We consider the massive star formation properties, radial profiles, and atomic gas masses of those galaxies in our Hα Galaxy Survey that have close companion...
  • Publication
    The Hα nature of the Universe at z ˜ 0.83
    We present here the results of a survey searching for current-star forming galaxies at at z ˜ 0.83. Objects are selected by their emission in the Hα line...

    The IAC Stripe 82 Legacy Project: a wide-area survey for faint surface brightness astronomy
    We present new deep co-adds of data taken within Stripe 82 of the Sloan Digital Sky Survey (SDSS), especially stacked to reach the faintest surface brightness...

    The impact from survey depth and resolution on the morphological classification of galaxies
    We consistently analyse for the first time the impact of survey depth and spatial resolution on the most used morphological parameters for classifying galaxies...
