In the present results from a program of near-IR scanning of planetary nebulae, the observed flux is in most cases dominated by free-free emission. In three of...
Near-infrared Spectral Homogeneity of the Didymos System Before and After the DART Impact
We spectroscopically characterized the Didymos system, target of the Double Asteroid Redirection Test (DART)/Light Italian Cubesat for Imaging of Asteroids...
Near-infrared spectral variation in Ryugu particles and implication for rapid space weathering by solar UV radiation
The 2.7 µm absorption band, represented by OH groups, in the near-infrared reflectance spectra of primitive Solar System bodies could be an indicator of the...
Near-infrared spectroscopic indices for unresolved stellar populations. III. Composite indices definition as age and metallicity tracers and model comparison
Recent advances in the stellar population studies of unresolved galaxies in the NIR domain demonstrated that it contains several line-strength indices to be...
Near-infrared spectroscopic survey of B-type asteroids: Compositional analysis
We present near-infrared spectra of 23 B-type asteroids obtained with the NICS camera-spectrograph at the 3.56 m Telescopio Nazionale Galileo. We also compile...
Aims: The characterisation of the stellar population in young high-mass star-forming regions allows fundamental cluster properties like distance and age to be...
Near-infrared spectroscopy of 1999 JU3, the target of the Hayabusa 2 mission
Context. Primitive asteroids contain complex organic material and ices relevant to the origin of life on Earth. These types of asteroids are the target of...
Near-infrared spectroscopy of nearby Seyfert galaxies - I. First results
We present near-infrared 1.5-2.5μm moderate-resolution long-slit spectra of two Seyfert 1 galaxies (NGC 1097 and 1566), three Seyfert 2s (NGC 1386, 4945 and...
Near-infrared spectroscopy of nearby Seyfert galaxies - II. Molecular content and coronal emission
We present subarcsec near-infrared 1.5-2.5 μm moderate resolution long-slit spectra of eight nearby Seyfert galaxies (z 0.01), both parallel to the ionization...
