Welcome to the new MILES website

This is a website dedicated to the scientific exploitation of a new set of stellar libraries and stellar population synthesis models for the study of stars and galaxies, and their evolution.

The main emphasis of this page goes into the stellar library (MILES) developed for stellar population synthesis models. The library consist of ~1000 stars spanning a large range in atmospheric parameters. The spectra were obtained at the 2.5m INT telescope and cover the range 3525-7500Å at 2.50Å (FWHM) spectral resolution. In addition we also provide spectra for the near-IR Ca II triplet stellar library, 8350-9020Å and 1.5Å (FWHM), and SSP models. The spectral resolution, spectral type coverage, flux calibration accuracy and number of stars in both libraries represent a substantial improvement over previous libraries used in population synthesis models.

In this website we give access to both the STELLAR LIBRARIES and STELLAR POPULATION MODELS developed by our group, as well as a set of WEBTOOLS to retrieve, handle and transform them. 

LATEST NEWS

  • [15 April 2015] We have updated this website with new versions of the stellar population models (v10.0). Main changes include the new extended MILES models for varying [α/Fe] ratios (Vazdekis et al. 2015) and an extension to the spectral range 2.5--5.0 μm (MIUSCATIR, Röck et al. 2015). Details on the improvements/changes from v9.2 can be found here.
