NED Abstract

Copyright by Royal Astronomical Society. 2001MNRAS.326..745M Near-infrared template spectra of normal galaxies: k-corrections, galaxy models and stellar populations F. Mannucci, F. Basile, B.M. Poggianti, A. Cimatti, E. Daddi, L. Pozzetti and L. Vanzi Accepted 2001 April 30. Received 2001 April 27; in original form 2000 December 29 ABSTRACT We have observed 28 local galaxies in the wavelength range between 1 and 2.4 microns 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 x 53 arcsec^2^) 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 microns. 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.
