    The discrepancy between dynamical and stellar masses in massive compact galaxies traces non-homology
    For many massive compact galaxies, their dynamical masses (Mdyn ∝ σ2re) are lower than their stellar masses (M⋆). We analyse the unphysical mass discrepancy M⋆...

    The DiskMass Survey. X. Radio synthesis imaging of spiral galaxies
    We present results from 21 cm radio synthesis imaging of 28 spiral galaxies from the DiskMass Survey obtained with the VLA, WSRT, and GMRT facilities. We detail...

    The distance to the C component of I Zw 18 and its star formation history. A probabilistic approach
    Aims: We analyzed the resolved stellar population of the C component of the extremely metal-poor dwarf galaxy I Zw18 in order to evaluate its distance and star...

    The distribution of atomic hydrogen in EAGLE galaxies: morphologies, profiles, and H I holes
    We compare the mass and internal distribution of atomic hydrogen (H I) in 2200 present-day central galaxies with Mstar > 1010 M⊙ from the 100 Mpc EAGLE...

    The distribution of galaxy morphological types and the morphology-mass relation in different environments at low redshift
    We use ˜2000 galaxies from PM2GC (Calvi, Poggianti & Vulcani 2011a) belonging to different environments to show how the fractions of different galaxy...

    The Distribution of Star Formation in the Central Regions of Spiral Galaxies
    Nuclear rings are characterized by their high star formation rates, and are believed to be the products of gas inflow towards the inner regions of spiral...

    The diverse cold molecular gas contents, morphologies, and kinematics of type-2 quasars as seen by ALMA
    We present CO(2−1) and adjacent continuum observations of seven nearby radio-quiet type-2 quasars (QSO2s) obtained with ALMA at ∼0.2″ resolution (370 pc at z ∼...

    The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
    We present the first simulated galaxy clusters (M200 > 1014 M⊙) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater...

    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...
