    First detection of VHE gamma-ray signal from the FSRQ TON 0599
    TON 0599 (z = 0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, $E > 100$ GeV) gamma-ray band. Its redshift...

    First Ground-based Charge-coupled Device Proper Motions for Fornax. II. Final Results
    We present the first entirely ground-based astrometric determination of the proper motion for the Fornax Local Group dwarf spheroidal satellite galaxy of the...
  • Publication
    First Insights into the Spitzer Wide-Area Infrared Extragalactic Legacy Survey (SWIRE) Galaxy Populations
    We characterize the Spitzer Wide-area Infrared Extragalactic Legacy Survey (SWIRE) galaxy populations in the SWIRE validation field within the Lockman Hole...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
