Falcón Barroso, J. ; Sánchez Blázquez, P. ; Vazdekis, A. ; Ricciardelli, E. ; Cardiel López, Nicolás ; Cenarro, A. J. ; Gorgas García, Francisco Javier ; Peletier, R. F. | EDP Sciencies | 2011-08We present a number of improvements to the MILES library and stellar population models. We correct some small errors in the radial velocities of the stars, measure the spectral resolution of the library and models more accurately, and give a bet[...]texto impreso
Cenarro, A. J. ; Sánchez Blázquez, Patricia ; Cardiel López, Nicolás ; Gorgas García, Francisco Javier | IOP Publishing | 2004-10-20We present measurements of the Ca II triplet and the Ca4227 Lick index for a sample of early-type galaxies in the Coma Cluster, deriving, for the first time, their corresponding relationships with velocity dispersion. Compared with a similar sub[...]texto impreso
Cenarro, A. J. ; Cardiel López, Nicolás ; Gorgas García, Francisco Javier ; Peletier, R. F. ; Vazdekis, A. ; Prada, F. | Wiley | 2001-09-21A new stellar library at the near-IR spectral region developed for the empirical calibration of the Ca II triplet and stellar population synthesis modelling is presented. The library covers the range lambda lambda 8348-9020 at 1.5-Angstrom (FWHM[...]texto impreso
Cenarro, A. J. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Pedraz, S. ; Peletier, R. F. ; Vazdekis, A. | Wiley | 2001-09-21We present a homogeneous set of stellar atmospheric parameters (T-eff, log g, [Fe/H]) for a sample of about 700 field and cluster stars which constitute a new stellar library in the near-IR developed for stellar population synthesis in this spec[...]texto impreso
Cenarro, A. J. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Vazdekis, A. ; Peletier, R. F. | Wiley | 2002-02-01Using a near-infrared stellar library of 706 stars with a wide coverage of atmospheric parameters, we study the behaviour of the Call triplet strength in terms of effective temperature, surface gravity and metallicity. Empirical fitting function[...]texto impreso
Mármol Queraltó, E. ; Cardiel López, Nicolás ; Sánchez Blázquez, P. ; Trager, S. C. ; Peletier, R. F. ; Kuntschner, H. ; Silva, D. R. ; Cenarro, A. J. ; Vazdekis, A. ; Gorgas García, Francisco Javier | IOP publishing ltd | 2009-11-10The study of stellar populations in early-type galaxies in different environments is a powerful tool for constraining their star formation histories. This study has been traditionally restricted to the optical range, where dwarfs around the turn[...]texto impreso
Vazdekis, A. ; Sánchez Blázquez, P. ; Falcón Barroso, J. ; Cenarro, A. J. ; Beasley, M. A. ; Cardiel López, Nicolás ; Gorgas García, Francisco Javier ; Peletier, R. F. | Wiley | 2010-06-01We present synthetic spectral energy distributions (SEDs) for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at moderately high resolution [full width at half-maximum (FWHM) = 2.3 A]. These SED[...]texto impreso

F. ; Gorgas García, Francisco Javier ; Gil de Paz, Armando ; Muñoz Mateos, Juan Carlos | EDP Sciencies | 2011-02We present new medium resolution kinematic data for a sample of 21 dwarf early-type galaxies (dEs) mainly in the Virgo cluster, obtained with the WHT and INT telescopes at the Roque de los Muchachos Observatory (La Palma, Spain). These data are [...]texto impreso
