Near-infrared spectroscopic indices for unresolved stellar populations. II. Index measurements
D. Gasparri, L. Morelli, V. D. Ivanov +7
We measured the equivalent width of a large set of near-infrared (NIR, 0.8--2.4m) line-strength indices in the XShooter medium-resolution spectra of the central regions of 14…
Infrared Telescope Facility (IRTF) spectral library II: New indices in Y, J, H, and L atmospheric windows
L. Morelli, V. D. Ivanov, A. Pizzella +6
Stellar population studies in the infrared (IR) wavelength range have two main advantages with respect to the optical regime: they probe different populations, because most of the…
Near Infrared spectroscopic indices for unresolved stellar populations. I. Template galaxy spectra
P. Francois, L. Morelli, A. Pizzella +5
A new generation of spectral synthesis models has been developed in the recent years, but there is no matching -- in terms of quality and resolution -- set of template galaxy spect…
IC 5181: An S0 Galaxy with Ionized Gas on Polar Orbits
Alessandro Pizzella, Lorenzo Morelli, Enrico Maria Corsini +2
The nearby S0 galaxy IC 5181 is studied to address the origin of the ionized gas component that orbits the galaxy on polar orbit. We perform detailed photometric and spectroscopic…
The external origin of the polar gaseous disk of the S0 galaxy IC 5181
Alessandro Pizzella, Lorenzo Morelli, Enrico Maria Corsini +2
Galaxies accrete material from the environment through acquisition and merging events. We study the nearby S0 galaxy IC 5181 to address the origin of the ionized-gas component orbi…
The Infrared Telescope Facility (IRTF) spectral library: spectral diagnostics for cool stars
Mary Cesetti, A. Pizzella, V. D. Ivanov +3
The near-infrared (NIR) wavelength range offers some unique spectral features, and it is less prone to the extinction than the optical one. Recently, the first flux calibrated NIR…
Structure and dynamics of galaxies with a low surface-brightness disc - II. Stellar populations of bulges
L. Morelli, E. M. Corsini, A. Pizzella +4
The radial profiles of the Hb, Mg, and Fe line-strength indices are presented for a sample of eight spiral galaxies with a low surface-brightness stellar disc and a bulge. The corr…
Multiband photometric decomposition of nuclear stellar disks
L. Morelli, M. Cesetti, E. M. Corsini +4
Small and bright stellar disks with scale lengths of few tens of parsec are known to reside in the center of galaxies. They are believed to have formed in a dissipational process a…
Early-type galaxies in the near-infrared: 1.5-2.4\mum spectroscopy
M. Cesetti, V. D. Ivanov, L. Morelli +6
Near-infrared (hereafter NIR) data may provide complementary information to the traditional optical population synthesis analysis of unresolved stellar populations because the spec…
