    INTEGRAL Spectroscopy of IRAS 17208-0014: Implications for the Evolutionary Scenarios of Ultraluminous Infrared Galaxies
    New integral field optical fiber spectroscopy obtained with the INTEGRAL system, together with archival HST WFPC2 and NICMOS images, has been used to...
  • Publication
    Integral-field kinematics and stellar populations of early-type galaxies out to three half-light radii
    We observed 12 nearby H i-detected early-type galaxies (ETGs) of stellar mass ˜1010 M⊙ ≤ M* ≤ ˜1011 M⊙ with the Mitchell Integral-Field Spectrograph, reaching...

    Integrated-light analyses vs. colour-magnitude diagrams. II. Leo A: an extremely young dwarf in the Local Group
    Context. Most of our knowledge of the stellar component of galaxies is based on the analysis of distant systems and comes from integrated light data. It is...

    Intense blazar activity in the photopolarimetric light curve of OJ 287
    We present a detailed analysis on photopolarimetric monitoring on OJ 287 conducted at the Nordic Optical Telescope during January 1991. Large rapid variations...

    Interacting galaxies in the nearby Universe: only moderate increase of star formation
    We investigate the influence of interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of ˜45 Mpc...

    Interactions and star formation
    We investigate the influence of interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of ~45 Mpc...

    Interactions and star-formation activity in Wolf-Rayet galaxies
    We present the main results of the Ph.D. thesis carried out by López-Sánchez (Ph.D. thesis, 2006), in which a detailed morphological, photometric and...

    Interactions between large-scale radio structures and gas in a sample of optically selected type 2 quasars
    Context. The role of radio mode feedback in non radio-loud quasars needs to be explored in depth to determine its true importance. Its effects can be identified...

    Intergalactic Globular Clusters and the Faint End of the Galaxy Number Counts in A1656 (Coma)
    The existence of an intergalactic globular cluster population in the Coma cluster of galaxies has been tested using surface brightness fluctuations. The main...
