    NGC 4672: A new case of an early-type disk galaxy with an orthogonally decoupled core
    We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and...

    NGC 6240: A triple nucleus system in the advanced or final state of merging
    Aims: NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two...

    NGC 6705 a young α-enhanced open cluster from OCCASO data
    Context. The stellar [α/Fe] abundance is sometimes used as a proxy for stellar age, following standard chemical evolution models for the Galaxy, as seen by...

    NICS-TNG infrared spectroscopy of NGC 1068: The first extragalactic measurement of [P II] and a new tool to constrain the origin of [Fe II] line emission in galaxies
    We report 0.9-1.4 mu m spectroscopic observations of NGC 1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the...

    NICS-TNG infrared spectroscopy of trans-neptunian objects 2000 EB173 and 2000 WR106
    We report complete near-infrared (0.9-2.4 mu m) spectral observations of trans-neptunian objects (TNOs) 2000 EB173 and 2000 WR106 collected using the new Near...

    NIR surface photometry of a sample of nearby spiral galaxies
    The first results of an observational programme aimed at mapping a sample of face-on spiral galaxies in the NIR are presented. This paper shows the surface...

    Nitrogen abundances in planet-harbouring stars
    We present a detailed spectroscopic analysis of nitrogen abundances in 91 solar-type stars, 66 with and 25 without known planetary mass companions. All...

    NLTE for APOGEE: simultaneous multi-element NLTE radiative transfer
    Context. Relaxing the assumption of local thermodynamic equilibrium (LTE) in modelling stellar spectra is a necessary step to determine chemical abundances to...

    No evidence for small disk-like bulges in a sample of late-type spirals
    Context. About 20% of low-redshift galaxies are late-type spirals with a small or no bulge component. Although they are the simplest disk galaxies in terms of...
