    Pyroclastic Blowout: Dust Survival in Isolated versus Clustered Supernovae
    Following the current debate on the fate of SN-condensed dust grains, here we explore by means of three-dimensional hydrodynamical simulations the interaction...

    QSO 2237+0305 VR Light Curves from Gravitational LensES International Time Project Optical Monitoring
    We present VR observations of QSO 2237+0305 conducted by the Gravitational Lensing International Time Project collaboration from 1999 October 1 to 2000 February...

    QSO size ratios from multiband monitoring of a microlensing high-magnification event
    We introduce a new scheme to study the nature of the central engine in a lensed QSO. The compact emission regions could have different sizes in different...

    QSO+Galaxy Association and Discrepant Redshifts in NEQ3
    Spectroscopy and deep imaging of the group NEQ3 are presented. This system is formed by three compact objects with relative separations of ~2.6" and ~2.8" and a...

    QSO2 outflow characterization using data obtained with OSIRIS at the Gran Telescopio Canarias
    Context. Ionized outflows are ubiquitous in non-radio-loud obscured quasars (QSO2s) at different redshifts. However, the actual size of the outflows and their...

    QSOFEED: Relationship between star formation and active galactic nuclei feedback
    Context. Large-scale cosmological simulations suggest that feedback from active galactic nuclei (AGN) plays a crucial role in galaxy evolution. More...

    QSOs and the survey OTELO
    OTELO is a survey of emission-line objects that will be carried out using tunable filters with OSIRIS at the GTC. The survey will have a deep impact on...

    Qualitative Interpretation of Galaxy Spectra
    We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put...
