    A jet-cloud interaction in the 3C 196 environment
    Powerful radio galaxies and radio-loud quasars at high redshifts are frequently associated with extended emission-line regions (EELRs). Here we investigate the...

    A joint XMM-NuSTAR observation of the galaxy cluster Abell 523: Constraints on inverse Compton emission
    Aims: We present the results of a joint XMM-Newton and NuSTAR observation (200 ks) of the galaxy cluster Abell 523 at z = 0.104. The peculiar morphology of the...

    A K-band central disc surface brightness correlation with scalelength for early-type disc galaxies, and the inclination correction
    The K-band light profiles from two statistically complete, diameter-limited samples of disc galaxies have been simultaneously modelled with a seeing-convolved...

    A Ks-band-selected catalogue of objects in the ALHAMBRA survey
    The original ALHAMBRA catalogue contained over 400 000 galaxies selected using a synthetic F814W image, to the magnitude limit AB(F814W) ≈ 24.5. Given the...
