    Quasars Do Not Live in Merging Systems: No Enhanced Merger Rate at z≲0.8
    We tackle the long-standing question “what is the relevance of major mergers and interactions as triggering mechanisms for AGN activity?” We study a sample of...

    Quasars with flare/eclipse-like variability identified in ZTF
    Active galactic nuclei (AGNs) are known to exhibit optical/ultraviolet variability and most of them can be well modelled by the damped random walks. Physical...

    Quasars with P v broad absorption in BOSS data release 9
    Broad absorption lines (BALs) found in a significant fraction of quasar spectra identify high-velocity outflows that might be present in all quasars and could...

    Quasi-periodic behaviour in the optical and γ-ray light curves of blazars 3C 66A and B2 1633+38
    We report on quasi-periodic variability found in two blazars included in the Steward Observatory Blazar Monitoring data sample: the BL Lac object 3C 66A and the...

    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)...

    Quenching cluster cooling flows with recurrent hot plasma bubbles
    The observed cooling rate of hot gas in clusters is much lower than that inferred from the gas density profiles. This suggests that the gas is being heated by...

    QUIJOTE scientific results - IX. Radio sources in the QUIJOTE-MFI wide survey maps
    We present the catalogue of Q-U-I JOint TEnerife (QUIJOTE) Wide Survey radio sources extracted from the maps of the Multi-Frequency Instrument compiled between...

    QUIJOTE Scientific Results - XVII. Studying the anomalous microwave emission in the Andromeda Galaxy with QUIJOTE-MFI
    The Andromeda Galaxy (M31) is the Local Group galaxy that is most similar to the Milky Way (MW). The similarities between the two galaxies make M31 useful for...
