    First multi-wavelength campaign on the gamma-ray-loud active galaxy IC 310
    Context. The extragalactic very-high-energy gamma-ray sky is rich in blazars. These are jetted active galactic nuclei that are viewed at a small angle to the...

    First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign
    We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed...

    First results from HerMES on the evolution of the submillimetre luminosity function
    We have carried out two extremely deep surveys with SPIRE, one of the two cameras on Herschel, at 250 μm, close to the peak of the far-infrared background. We...

    First stellar spectroscopy in Leo P
    We present the first stellar spectroscopy in the low-luminosity (MV ˜ -9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and...

    First steps of the GTC photometric calibration plan
    Large telescopes require a very precise calibration in order to maximize its scientific output. Current catalogues of standard stars are generally too bright...

    First survey of Wolf-Rayet star populations over the full extension of nearby galaxies observed with CALIFA
    The search of extragalactic regions with conspicuous presence of Wolf-Rayet (WR) stars outside the Local Group is challenging task owing to the difficulty in...

    First tentative detection of anisotropy in the QSO distribution around nearby edge-on spiral galaxies
    Aims:To check whether the polar angle distribution of QSOs around nearby spiral galaxies is isotropic or not. Methods: A statistical analysis of the polar angle...

    Fitting Liner Nuclei within the Active Galactic Nucleus Family: A Matter of Obscuration?
    In this paper, we study the nuclear obscuration of galaxies hosting low ionization narrow emission regions (LINERs) based on their X-ray and optical emission...

    Five young star clusters in the outer region of the Small Magellanic Cloud
    Colour-magnitude diagrams in the Washington system are presented for the first time for five star clusters projected on to the outer region of the Small...
