18 April 2017
- New E-MILES stellar population models released
This version includes the new E-MILES models extending the MILES predictions to the spectral range between 0.16 to 5.0um (see Vazdekis et al. 2016 for details). These models replace former MIUSCAT and MIUSCATIR models.
- New models include predictions for a larger number of IMF slopes, and shapes (including Chabrier IMF).
- General "clean-up" and reorganization of the MILES website
15 April 2015
- New MILES stellar population models with variable [α/Fe] released
This version includes the new MILES models for different [α/Fe] ratios (see Vazdekis et al. 2015 for details).
- New MIUSCATIR stellar population models between 2.5 and 5 μm.
Check out our dedicated webpage here (see also Röck et al. 2015)
- Version 10.0 of the models
Together with the new MILES and MIUSCATIR models, we have upgraded the previous set of models by providing predictions for different isochrones.
22 May 2012
- New MIUSCAT stellar population models released
This version includes the new MIUSCAT models (see here). These models are generated after combining the MILES, INDOUS and CaT stellar libraries (see Vazdekis et al. 2012 for details).
- Version 9.2 of the models
Together with the new MIUSCAT models, we have upgraded the previous set of models by providing predictions for a larger range of IMF slopes.
- Webpage organization
Some sections of the webpage (Model Predictions) have been split and re-arranged at the top of the tree menu. Besides the Lick/IDS line strength predictions, we provide photometric predictions based on photometric libraries (as in the past) and MIUSCAT SEDs (new!).
- Photometric predictions based on MIUSCAT SEDs
Predictions for the Johnson-Cousin, HST and SDSS filters are provided based on the MIUSCAT SEDs.
- 'Get spectra for SFH' webtool updated
The webtool has been updated so that a redshift different than zero is allowed. The resulting spectra has been scaled in flux by a (1+z) factor.

- Version 9.1 of the MILES stellar library and models released
We have corrected some stars in the stellar library for radial velocity osets with respect to the solar rest frame. We have also re-assessed the spectral resolution of the MILES library and models confirming that it is rather constant as a function of wavelength and have established that the new value is ≈2.5 Å for both the originally released (v9.0) and updated (v9.1) versions. We have also changed the scheme used to flux calibrate the spectra in the absolute sense. As a result we find an excellent agreement between fluxes measured from our spectra and those from predictions obtained by using photometric (rather than spectroscopic) libraries. See the Falcón-Barroso et al. (2011) for details.
- Normalization when redshift is larger than zero is now applied in our webtools [newflux = flux / (1+z)]
- Cousin R and I filters added to the filters_default.res file
1 April 2010
- Version 9.0 released
- A new version of the stellar libraries and stellar population models released.
- A webcast presenting the new library and the usage of the website is available here
- No rescaling of the spectra is applied in the webtools when redshift is larger than 0. Only the wavelength vector is modified
