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
Sánchez Blázquez, P. ; Gibson, B. K. ; Kawata, D. ; Cardiel López, Nicolás ; Balcells, M. | Wiley-Blackwell publishing Inc | 2009-12-11We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum as dry merger remnants and ongoing dry mergers. Kinematics, stellar population absorption features and ionization from emission lines are derived. We fi[...]texto impreso

Pérez González, Pablo Guillermo ; Cardiel López, Nicolás ; Eliche Moral, María del Carmen ; otros, ... | American Astronomical Society | 2016-04-01We present Keck I MOSFIRE spectroscopy in the Y and H bands of GDN-8231, a massive, compact, star-forming galaxy at a redshift of z ~ 1.7. Its spectrum reveals both H? and [Nii] emission lines and strong Balmer absorption lines. The H? and Spitz[...]texto impreso
Sánchez de Miguel, Alejandro ; Kyba, Christopher C. M. ; Aubé, Martin ; Zamorano Calvo, Jaime ; Cardiel López, Nicolás ; Tapia Ayuga, Carlos ; Bennie, Jon ; Gaston, Kevin J. | Elsevier Science INC | 2019-04Sensors on remote sensing satellites have provided useful tools for evaluation of the environmental impacts of nighttime artificial light pollution. However, due to their panchromatic nature, the data available from these sensors (VIIRS/DNB and [...]texto impreso
Peralta de Arriba, L. ; Balcells, M. ; Trujillo, I. ; Falcón Barroso, J. ; Tapia, T. ; Cardiel López, Nicolás ; Gallego Maestro, Jesús ; Guzmán, R. ; Hempel, A. ; Martín Navarro, I. ; Pérez González, Pablo Guillermo ; Sánchez Blázquez, P. | Wiley | 2015-10-11Several authors have reported that the dynamical masses of massive compact galaxies (M_? ? 10^11?M_?, r_e ? 1?kpc), computed as M_dyn=5.0 ?_e^2r_e/GMdyn=5.0 ?e2re/G, are lower than their stellar masses M_?. In a previous study from our group, th[...]texto impreso
We probe the merging channel of massive galaxies over the z= 0.3 ? 1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass > ? 1011M?, from the SHARDS survey. SHARDS provides medium band photometry equivalent to[...]texto impreso
Cardiel López, Nicolás ; Eliche Moral, María del Carmen ; Pascual, Sergio | Spie-Int Soc Optical Engineering | 2012FRIDA (inFRared Imager and Dissector for the Adaptive optics system of the Gran Telescopio Canarias) is designed as a diffraction limited instrument that will offer broad and narrow band imaging and integral field spectroscopy capabilities with [...]texto impreso
In many astronomical problems one often needs to determine the upper and/or lower boundary of a given data set. An automatic and objective approach consists in fitting the data using a generalized least-squares method, where the function to be m[...]texto impreso
Pascual Ramírez, Sergio ; Gallego Maestro, Jesús ; Cardiel López, Nicolás | Universidad Nacional Autónoma México, Instituto Astronomía | 2007EMIR (Balcells et al. 2000) is a near-infrared wide-field camera and multi-object spectrograph being built for the GTC. The Data Reduction Pipeline (DRP) will be optimized for handling and reducing near-infrared data acquired with EMIR.texto impreso
Barro, Guillermo ; Gallego Maestro, Jesús ; Pérez González, Pablo Guillermo ; Eliche Moral, María del Carmen ; Balcells, M. ; Villar, V. ; Cardiel López, Nicolás ; Cristobal Hornillos, D. ; Gil de Paz, Armando ; Guzmán, R. ; Pelló, R. ; Prieto, M. ; Zamorano Calvo, Jaime | SPRINGER-VERLAG BERLIN | 2010We present a study that links the NCs to the rest-frame luminosity functions (LFs) at the passbands probed by the observed K-band at different epochs. Making use of a large K-band selected sample in the Groth Field, HDFN and CDFS (?0.27deg^(2)),[...]texto impreso
Jiménez Esteban, F. M. ; Cabrera Lavers, A. ; Cardiel López, Nicolás ; Alacid, J. M. | Wiley | 2012-11The observation of blank fields, defined as regions of the sky that are devoid of stars down to a given threshold magnitude, constitutes one of the most relevant calibration procedures required for the proper reduction of astronomical data obtai[...]texto impreso
Pascual Ramírez, Sergio ; Gallego Maestro, Jesús ; Cardiel López, Nicolás ; Eliche Moral, María del Carmen | Universidad Nacional Autónoma Mexico, Inst. de Astronomía | 2013The UCM Instrumentation Group (GUAIX) is developing currently Data Reduction Pipelines (DRP) for four instruments of the GTC: EMIR, FRIDA, MEGARA and MIRADAS. The purpose of the DRPs is to provide astronomers scientific quality data, removing in[...]texto impreso
Sánchez Blázquez, Patricia ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Cenarro, J. ; González, J. J. | IOP Publishing | 2003-06-20Central line-strength indices were measured in the blue spectral region for a sample of 98 early-type galaxies in different environments. For most indices (Mg b and [Fe] in particular), elliptical galaxies in rich clusters and in low-density reg[...]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[...]
