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…
