    The dominant role of mergers in the size evolution of massive early-type galaxies since z ~ 1
    Aims: The role of galaxy mergers in massive galaxy evolution, and in particular to mass assembly and size growth, remains an open question. In this paper we...

    The downplayed role of secular processes in the co-evolution of galaxies and black holes
    According to the current co-evolution picture, most present-day galaxies experienced at least one phase of vigorous black hole (BH) activity in the past, during...

    The drop in the cosmic star formation rate below redshift 2 is caused by a change in the mode of gas accretion and by active galactic nucleus feedback
    The cosmic star formation rate is observed to drop sharply after redshift z= 2. We use two large, cosmological, smoothed particle hydrodynamics simulations to...

    The dual nature of blazar fast variability: Space and ground observations of S5 0716+714
    Blazar S5 0716+714 is well-known for its short-term variability, down to intraday time-scales. We here present the 2-min cadence optical light curve obtained by...

    The Dust and Molecular Gas in the Brightest Cluster Galaxy in MACS 1931.8-2635
    We present new Atacama Large Millimeter Array observations of the molecular gas and far-infrared continuum around the brightest cluster galaxy (BCG) in the cool...

    The Dust and [C II] Morphologies of Redshift ∼4.5 Sub-millimeter Galaxies at ∼200 pc Resolution: The Absence of Large Clumps in the Interstellar Medium at High-redshift
    We present deep, high-resolution (0.″03, 200 pc) ALMA Band 7 observations covering the dust continuum and [C II] λ157.7 μm emission in four z ∼ 4.4–4.8 sub...

    The dust content of high-z submillimeter galaxies revealed by Herschel
    We use deep observations taken with the Photodetector Array Camera and Spectrometer (PACS), on board the Herschel satellite as part of the PACS evolutionary...

    The dust masses of powerful radio galaxies: clues to the triggering of their activity
    We use deep Herschel Space Observatory observations of a 90 per cent complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 z 0.7) with strong...

    The dust morphology of the elliptical Galaxy M 86 with SPIRE
    We present Herschel-SPIRE observations at 250-500 μm of the giant elliptical galaxy M 86 and examine the distribution of the resolved cold dust emission and its...
