    The nearest extreme starburst: bubbles, young star clusters and outflow in the merger NGC 3256
    We have studied the extreme starburst in the infrared merger NGC 3256. We detect four galactic bubbles (using ESO New Technology Telescope and Hubble Space...

    The Nearest Ultra Diffuse Galaxy: UGC 2162
    We describe the structural, stellar population and gas properties of the nearest ultra diffuse galaxy discovered so far: UGC 2162 (z = 0.00392 {R}e,g=1.7(+/- 0...

    The NGC 346 massive star census. Nitrogen abundances for apparently single, narrow lined, hydrogen core burning B-type stars
    Previous analyses of two large spectroscopic surveys of early-type stars in the Large Magellanic Cloud (LMC) have found an excess of nitrogen enriched B-type...

    The NIR Ca ii triplet at low metallicity. Searching for extremely low-metallicity stars in classical dwarf galaxies
    The NIR Ca ii triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group...

    The NOEMA observations of GN-z11: constraining the neutral interstellar medium and dust formation in the heart of cosmic reionization at z = 10.6
    We present results of dust continuum and [C II]$\, 158\, {\rm \mu m}$ emission line observations of a remarkably UV luminous (M UV = -21.6) galaxy at z = 10.603...

    The nuclear activity and central structure of the elliptical galaxy NGC 5322
    We have analysed a new high-resolution e-MERLIN 1.5 GHz radio continuum map together with HST and SDSS imaging of NGC 5322, an elliptical galaxy hosting radio...

    The nuclear and extended infrared emission of the Seyfert galaxy NGC 2992 and the interacting system Arp 245
    We present subarcsecond resolution infrared (IR) imaging and mid-IR (MIR) spectroscopic observations of the Seyfert 1.9 galaxy NGC 2992, obtained with the...

    The nuclear and extended mid-infrared emission of Seyfert galaxies
    We present subarcsecond resolution mid-infrared (MIR) images obtained with 8-10 m-class ground-based telescopes of a complete volume-limited (DL 40 Mpc) sample...

    The nuclear and integrated far-infrared emission of nearby Seyfert galaxies
    We present far-infrared (FIR) 70-500 μm imaging observations obtained with Herschel/Photodetector Array Camera (PACS) and Spectral and Photometric Imaging...
