    Quantitative spectroscopic criteria for the classification of pre-main sequence low-mass stars.
    The discovery of hundreths of X-ray emitting stars possibly associated with pre-main sequence (PMS) low-mass stars far from molecular clouds, makes it necessary...

    Quasar 3C 298: a test-case for meteoritic nanodiamond 3.5μm emission
    Aims:We calculate the dust emission expected at 3.43 and 3.53 μm if meteoritic (i.e. hydrogenated) nanodiamonds are responsible for most of the far-UV break...

    Quasi-stellar objects in the ALHAMBRA survey. I. Photometric redshift accuracy based on 23 optical-NIR filter photometry
    Context. Even the spectroscopic capabilities of today's ground and space-based observatories can not keep up with the enormous flow of detections (>105 deg-2)...

    Radial brightness profiles of extragalactic H II regions
    We present a systematic study of the radial brightness profiles in H alpha of a set of H ii regions in 6 late-type spiral galaxies, complete down to stated...

    Radial distribution of gas and dust in spiral galaxies . The case of M 99 (NGC 4254) and M 100 (NGC 4321)
    By combining Herschel-SPIRE data with archival Spitzer, H i , and CO maps, we investigate the spatial distribution of gas and dust in the two famous grand...

    Radial distribution of near-UV flux in disc galaxies in the range 0 ⪉ z ⪉ 1
    Context: In the last 8 Gyr of cosmic time the global star formation rate (SFR) has declined by roughly an order of magnitude, and most of this activity has been...

    Radial distribution of the multiple stellar populations in ω Centauri
    Aims: We present a detailed study of the radial distribution of the multiple populations identified in the Galactic globular cluster ω Cen. Methods: We used...

    Radial gradients of CO absorptions and abundance ratios in the bulge of M31
    We present new H- and K-band spectroscopy for the bulge of M31, taken with the LUCI spectrograph at the Large Binocular Telescope (LBT). We studied radial...
