    AGN Activity and Circumnuclear Star Formation in Nearby Galaxies
    We have selected a sample of nearby galaxies where an AGN (Seyfert or LINER) coexists with circumnuclear star formation. We use the highest spatial resolution...

    AGN activity in Local Luminous Infrared Galaxies
    Luminous Infrared Galaxies (LIR=10^11-10^12Lsun) have star formation rates in the range of ~20-200Msun/yr. In the local Universe ~50% LIRGs show AGN or AGN/SB...

    Alone on a wide wide sea. The origin of SECCO 1, an isolated star-forming gas cloud in the Virgo cluster*†‡
    SECCO 1 is an extremely dark, low-mass (M⋆ ≃ 105 M⊙), star-forming stellar system lying in the low-velocity cloud (LVC) substructure of the Virgo cluster of...

    An ALMA/NOEMA survey of the molecular gas properties of high-redshift star-forming galaxies
    We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We...

    An Empirical Relation between the Large-scale Magnetic Field and the Dynamical Mass in Galaxies
    The origin and evolution of cosmic magnetic fields as well as the influence of the magnetic fields on the evolution of galaxies are unknown. Though not without...

    An ionized superbubble powered by a protocluster at z = 6.5
    We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...

    An optical/NIR survey of globular clusters in early-type galaxies
    The colour distribution of globular cluster (GC) systems in the majority of galaxies is bi/multimodal in optical colours. It is widely accepted that multiple...

    Assessing the accuracy of star formation rate measurements by direct star count in molecular clouds
    Star formation estimates based on the counting of young stellar objects (YSOs) are commonly carried out for nearby star-forming regions in the Galaxy, and in...

    Automatic unsupervised classification of all Sloan Digital Sky Survey Data Release 7 galaxy spectra
    Using the k-means cluster analysis algorithm, we carry out an unsupervised classification of all galaxy spectra in the seventh and final Sloan Digital Sky...
