The X-shooter Spectral Library (XSL): Data Release 3
Kristiina Verro, S. C. Trager, R. F. Peletier +12
We present the third data release (DR3) of the X-shooter Spectral Library (XSL). This moderate-to-high resolution, near-ultraviolet-to-near-infrared ( nm, R 10 000…
Carbon stars in the X-Shooter Spectral Library: II. Comparison with models
A. Gonneau, A. Lançon, S. C. Trager +6
In a previous paper, we assembled a collection of medium-resolution spectra of 35 carbon stars, covering optical and near-infrared wavelengths from 400 to 2400 nm. The sample inclu…
UV-extended E-MILES stellar population models: young components in massive early-type galaxies
A. Vazdekis, M. Koleva, E. Ricciardelli +2
We present UV-extended E-MILES stellar population synthesis models covering the spectral range 1680-50000A at moderately high resolution. We employ the NGSL space-based stellar lib…
MILES extended: Stellar population synthesis models from the optical to the infrared
B. Röck, A. Vazdekis, E. Ricciardelli +3
We present the first single-burst stellar population models which covers the optical and the infrared wavelength range between 3500 and 50000 Angstrom and which are exclusively bas…
Carbon stars in the X-shooter Spectral Library
A. Gonneau, A. Lançon, S. C. Trager +13
We provide a new collection of spectra of 35 carbon stars obtained with the ESO/VLT X-shooter instrument as part of the X-shooter Spectral Library project. The spectra extend from…
Single Stellar Populations in the Near-Infrared - I. Preparation of the IRTF spectral stellar library
S. Meneses-Goytia, R. F. Peletier, S. C. Trager +3
We present a detailed study of the stars of the IRTF spectral library to understand its full extent and reliability for use with Stellar Population (SP) modeling. The library consi…
Single stellar populations in the near-infrared II. Synthesis models
S. Meneses-Goytia, R. F. Peletier, S. C. Trager +1
We present unresolved single stellar population synthesis models in the near-infrared (NIR) range. The extension to the NIR is important for the study of early-type galaxies, since…
The X-shooter Spectral Library (XSL): I. DR1. Near-ultraviolet through optical spectra from the first year of the survey
Yan-Ping Chen, S. C. Trager, R. F. Peletier +5
We present the first release of XSL, the X-Shooter Spectral Library. This release contains 237 stars spanning the wavelengths 3000--10200 Å observed at a resolving power $R \equiv…
Stellar population models in the UV: I. Characterisation of the New Generation Stellar Library
Mina Koleva, Alexander Vazdekis Vazdekis
The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quali…
Evolutionary Stellar Population Synthesis with MILES. Part I: The Base Models and a New Line Index System
A. Vazdekis, P. Sánchez-Blázquez, J. Falcón-Barroso +5
[Abridged]. We present SEDs for single-age, single-metallicity stellar populations (SSPs) covering the optical range at resolution 2.3A (FWHM). These SEDs constitute our base model…
