    Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT
    The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic...

    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+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...

    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...

    Quantifying Resonant Structure in NGC 6946 from Two-dimensional Kinematics
    We study the two-dimensional kinematics of the Hα-emitting gas in the nearby barred Scd galaxy NGC 6946, in order to determine the pattern speed of the primary...

    Quantifying Star Formation Activity in the Inner 1 kpc of Local MIR Bright QSOs
    We examine star formation activity in a distant (z 0.1) and flux-limited sample of quasars (QSOs). Midinfrared (MIR) spectral diagnostics at high spatial...

    Quantitative Morphology of Galaxies in the Core of the Coma Cluster
    We present a quantitative morphological analysis of 187 galaxies in a region covering the central 0.28 deg2 of the Coma Cluster. Structural parameters from the...

    Quantitative Spectral Analysis of Early B-Type Supergiants in the Sculptor Galaxy NGC 300
    The spectra of two early B-type supergiant stars in the Sculptor spiral galaxy NGC 300 are analyzed by means of non-LTE line-blanketed unified model atmospheres...
