    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...

    Nuclear obscuration in LINERs. Clues from Spitzer/IRS spectra on the Compton thickness and the existence of the dusty torus
    Context. Most of the optically classified low-ionisation, narrow emission-line regions (LINERs) nuclei host an active galactic nucleus (AGN). However, how they...

    Nuclear Rings in Galaxies—a Kinematic Perspective
    We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of...

    Nuclear Spirals as Feeding Channels to the Supermassive Black Hole: The Case of the Galaxy NGC 6951
    We report the discovery of gas streaming motions along nuclear spiral arms toward the LINER nucleus of the galaxy NGC 6951. The observations, obtained using the...

    Nuclear Star Formation Activity and Black Hole Accretion in Nearby Seyfert Galaxies
    Recent theoretical and observational works indicate the presence of a correlation between the star-formation rate (SFR) and active galactic nucleus (AGN)...
