    Quantifying the scale of star formation across the Perseus spiral arm using young clusters around Cas OB5
    Context. Cas OB5 is an OB association located at a distance of 2.5–3 kpc that intercepts the Perseus spiral arm. It carries a moderate amount of reddening (A V...

    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)...

    Quiet-Sun inter-network magnetic fields observed in the infrared
    This paper presents the results of an investigation of the quiet Sun's magnetic field based on high-resolution infrared spectropolarimetric observations...

    QUIJOTE scientific results: XVIII. New constraints on the polarisation of the anomalous microwave emission in bright Galactic regions: ρ Ophiuchi, Perseus, and W43
    This work focuses on the study of the anomalous microwave emission (AME), an important emission mechanism between 10 and 60 GHz whose polarisation properties...

    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...
