    The Hubble Catalog of Variables (HCV)
    Aims: Over its lifetime and despite not being a survey telescope, the Hubble Space Telescope (HST) has obtained multi-epoch observations by multiple, diverse...

    The Hubble Missing Globular Cluster Survey: I. Survey overview and the first precise age estimate for ESO452-11 and 2MASS-GC01
    We present the Hubble Missing Globular Cluster Survey (MGCS), a Hubble Space Telescope Treasury Program dedicated to the observation of all kinematically...

    The hydrodynamics and ionization structure of gaseous nebulae. I. The time-dependent solution
    We present a one-dimensional numerical scheme that allows for the simultaneous solution of the hydrodynamic equations coupled with energy and ionization...

    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...

    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...

    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]...
