    The hydrostatic-to-lensing mass bias from resolved X-ray and optical-IR data
    An accurate reconstruction of galaxy cluster masses is key to use this population of objects as a cosmological probe. In this work we present a study on the...

    The hypergiant HR 8752 evolving through the yellow evolutionary void
    Context. We study the time history of the yellow hypergiant HR 8752 based on high-resolution spectra (1973-2005), the observed MK spectral classification data...

    The Hα environment of T Tauri resolved by speckle interferometry.
    T Tauri, the prototype of a class of low-mass pre-main sequence stars, was observed with the 3.6m Canada-France-Hawaii telescope (CFHT) and the CP40 photon...
  • Publication
    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 IACOB project . III. New observational clues to understand macroturbulent broadening in massive O- and B-type stars
    Context. The term macroturbulent broadening is commonly used to refer to a certain type of non-rotational broadening affecting the spectral line profiles of O-...
  • Publication
    The IACOB project. I. Rotational velocities in northern Galactic O- and early B-type stars revisited. The impact of other sources of line-broadening
    Context. Stellar rotation is an important parameter in the evolution of massive stars. Accurate and reliable measurements of projected rotational velocities in...
