    Non-circular motion evidence in the circumnuclear region of M100 (NGC 4321)
    We analyse new integral-field spectroscopy of the inner region (central 2.5 kpc) of the spiral galaxy NGC 4321 to study the peculiar kinematics of this region...

    Non-Gaussianity of optical emission lines in SDSS star-forming galaxies and its implications on galactic outflows
    The shape of emission lines in the optical spectra of star-forming galaxies reveals the kinematics of the diffuse gaseous component. We analyse the shape of...

    Non-solar abundance ratios trends of dEs in the Fornax Cluster using newly defined high-resolution indices
    We perform a detailed study of the stellar populations in a sample of massive Fornax dwarf galaxies using a set of newly defined line indices. Using data from...

    Nonaxisymmetric models of galaxy velocity maps
    Galaxy velocity mapsoften show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the...

    Nuclear 11.3 μm PAH emission in local active galactic nuclei
    We present Gran Telescopio CANARIAS CanariCam 8.7 μm imaging and 7.5-13 μm spectroscopy of six local systems known to host an active galactic nucleus (AGN) and...

    Nuclear Activity and Massive Star Formation in the Low-Luminosity Active Galactic Nucleus NGC 4303: Chandra X-Ray Observations
    We present evidence of the coexistence of either an AGN or an ultraluminous X-ray source, together with a young superstellar cluster, in the central 3 pc of NGC...

    Nuclear molecular outflow in the Seyfert galaxy NGC 3227
    ALMA observations have revealed nuclear dusty molecular disks or tori with characteristic sizes 15-40 pc in the few Seyferts and low -luminosity AGN that have...
