Matkovic, A. ; Guzmán, R. ; Sánchez Blázquez, P. ; Cardiel López, Nicolás ; Gorgas García, Francisco Javier | American Institute of Physics | 2009We derive ages, metallicities and [alpha/Fe] ratios for dwarf early-type galaxies (dE/dS0) in the center and a region believed to be infalling into the Coma cluster. We find that a set of metallic indices cannot be described by linear relations [...]texto impreso
We report the results on the EMIR1 (Espectrografo Multiobjeto Infra-Rojo) performances after the commissioning period of the instrument at the Gran Telescopio Canarias (GTC). EMIR is one of the first common user instruments for the GTC, the 10 m[...]texto impreso
Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Pedraz, S. ; González, J. J. | EDP Sciences | 1999-10Empirical fitting functions, describing the behaviour of the ?4000 Å break, D_4000, in terms of effective temperature, metallicity and surface gravity, are presented. For this purpose, the break has been measured in 392 stars from the Lick/IDS L[...]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
Pérez González, Pablo Guillermo ; Cardiel López, Nicolás ; Gallego Maestro, Jesús | Wiley | 2014-10-11We are undertaking a search for high-redshift low-luminosity Lyman Alpha sources in the SHARDS (Survey for High-z Absorption Red and Dead Sources) survey. Among the pre-selected Lyman Alpha sources two candidates were spotted, located 3.19 arcse[...]texto impreso
Sánchez de Miguel, Alejandro ; Bará, Salvador ; Aubé, Martin ; Cardiel López, Nicolás | MDPI | 2019-04Night-time lights interact with human physiology through different pathways starting at the retinal layers of the eye; from the signals provided by the rods; the S-, L- and M-cones; and the intrinsically photosensitive retinal ganglion cells (ip[...]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
Pedraz, S. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Sánchez Blázquez, P. ; Guzmán, R. | Wiley | 2002-05In this letter we investigate the kinematical properties of early-type dwarfs by significantly enlarging the scarce observational sample so far available. We present rotation curves and mean velocity dispersions for four bright dwarf ellipticals[...]texto impreso
Borlaff, Alejandro ; Eliche Moral, María del Carmen ; Beckman, John E. ; Ciambur, Bogdan C. ; Pérez González, Pablo Guillermo ; Barro, Guillermo ; Cava, Antonio ; Cardiel López, Nicolás | EDP Sciencies | 2017-08Context. The controversy about the origin of the structure of early-type S0-E/S0 galaxies may be due to the difficulty of comparing surface brightness profiles with different depths, photometric corrections and point spread function (PSF) effect[...]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
Brauneck, U. ; Gallego Maestro, Jesús ; Cardiel López, Nicolás ; Cabello, N. ; Guzmán, R. ; Rodríguez-Espinosa, J.M. ; Herrero, A. ; Mass-Hessee, M. ; Salvador, E. ; Manrique, A. ; Marín-Franch, A. | Spie-Int Soc Optical Engineering | 2018We present the first results using a new SCHOTT 1% narrow band filter in the near infrared for the CIRCE camera of the 10.4m GTC telescope. The goal of the project is to detect very distant galaxies at the dawn of the Universe. These remote and [...]texto impreso

As part of the tests carried out to verify the performance of the instrument in its two modes (IFU & MOS) and 18 spectral setups (ident[...]texto impreso
Cardiel López, Nicolás ; Gallego Maestro, Jesús ; Pascual Ramírez, Sergio | Spie-Int Soc Optical Engineering | 2016FRIDA is a diffraction-limited imager and integral-field spectrometer that is being built for the adaptive-optics focus of the Gran Telescopio Canarias. In imaging mode FRIDA will provide scales of 0.010, 0.020 and 0.040 arcsec/pixel and in IFS [...]
