A Method of Correcting Near‐Infrared Spectra for Telluric Absorption*

William D. Vacca, +2 more

Publications of the Astronomical Society...

TL;DR: In this article, a method for correcting near-infrared medium-resolution spectra for telluric absorption is presented, which makes use of a spectrum of an A0 V star, observed near in time and close in air mass to the target object, and a high-resolution model of Vega.

Dust in active nuclei. I. Evidence for "anomalous" properties

arXiv: Astrophysics

TL;DR: In this article, the authors present observational evidences that dust in the circumnuclear region of AGNs has different properties than in the Galactic diffuse interstellar medium, and they find that the E(B-V)/N_H ratio is nearly always lower than Galactic by a factor ranging from ~3 up to ~100.

Near-infrared template spectra of normal galaxies: k-corrections, galaxy models and stellar populations

Abstract: We have observed 28 local galaxies in the wavelength range between 1 and 2.4 μm in order to define template spectra of the normal galaxies along the Hubble sequence. Five galaxies per morphological type were observed in most cases, and the resulting rms spread of the normalized spectra of each class, including both intrinsic differences and observational uncertainties, is about 1 per cent in K, 2 per cent in H and 3 per cent in J. Many absorption features can be accurately measured. The target galaxies and the spectroscopic aperture (7×53 arcsec2) were chosen to be similar to those used by Kinney et al. to define template UV and optical spectra. The two data sets are matched in order to build representative spectra between 0.1 and 2.4 μm. The continuum shape of the optical spectra and the relative normalization of the near-IR ones were set to fit the average effective colours of the galaxies of the various Hubble classes. The resulting spectra are used to compute the k-corrections of the normal galaxies in the near-IR bands, and to check the predictions of various spectral synthesis models: while the shape of the continuum is generally well predicted, large discrepancies are found in the absorption lines. Among the other possible applications, here we also show how these spectra can be used to place constraints on the dominant stellar population in local galaxies. Spectra and k-corrections are publicly available and can be downloaded from the web site http://www.arcetri.astro.it/~filippo/spectra.
