    Probing nuclear activity versus star formation at z ˜ 0.8 using near-infrared multi-object spectroscopy
    We present near-infrared (NIR) spectroscopic observations of 28 X-ray and mid-infrared selected sources at a median redshift of z ˜ 0.8 in the Extended Groth...

    Probing the Baryon Cycle of Galaxies with SPICA Mid- and Far-Infrared Observations
    The SPICA mid- and far-infrared telescope will address fundamental issues in our understanding of star formation and ISM physics in galaxies. A particular...
  • Publication
    Probing the Dark Matter Radial Profile in Lens Galaxies and the Size of X-Ray Emitting Region in Quasars with Microlensing
    We use X-ray and optical microlensing measurements to study the shape of the dark matter density profile in the lens galaxies and the size of the (soft) X-ray...
  • Publication
    Probing the early chemical evolution of the Sculptor dSph with purely old stellar tracers
    We present the metallicity distribution of a sample of 471 RR Lyrae (RRL) stars in the Sculptor dSph, obtained from the I-band period-luminosity relation. It is...
  • Publication
    Probing the existence of a rich galaxy overdensity at z = 5.2
    We report the results of a pilot spectroscopic program of a region at z = 5.2 in the GOODS-N field containing an overdensity of galaxies around the well-known...
  • Publication
    Probing the high-redshift universe with SPICA: Toward the epoch of reionisation and beyond
    With the recent discovery of a dozen dusty star-forming galaxies and around 30 quasars at z > 5 that are hyper-luminous in the infrared (μ L IR > 1013 L⊙, where...
  • Publication
    Probing the Intermediate-Age Globular Clusters in NGC 5128 from Ultraviolet Observations
    We explore the age distribution of the globular cluster (GC) system of the nearby elliptical galaxy NGC 5128 using ultraviolet (UV) photometry from GALEX...
  • Publication
    Probing the low surface brightness outskirts of Milky Way dSphs: Sextans
    Faint dwarf galaxies such as those found around the Milky Way (MW) display the largest known dynamical mass-to-light ratios (up to several 100s M⊙/L⊙). However...
  • Publication
    Probing the molecular interstellar medium of M82 with Herschel-SPIRE spectroscopy
    We present the observations of the starburst galaxy M82 taken with the Herschel SPIRE Fourier-transform spectrometer. The spectrum (194-671 μm) shows a...
