Cardiel López, Nicolás ; Gorgas García, Francisco Javier ; Aragón Salamanca, A. | Wiley | 1998-08-21We have obtained radial gradients in the spectral features of the lambda 4000-Angstrom break (D(4000)) and Mg(2) for a sample of 11 central cluster galaxies (CCGs): eight in clusters with cooling flows and three in clusters without. After carefu[...]texto impreso
Cardiel López, Nicolás ; Gorgas García, Francisco Javier ; Aragón Salamanca, A. | Wiley-Blackwell | 1995-11-15Spectroscopic observations of central dominant cluster galaxies, with and without cooling flows, are presented. Through the analysis of absorption spectral features, namely the strength of the magnesium absorption at 5175 Å and the 4000 Å break,[...]texto impreso

Sánchez de Miguel, Alejandro ; Gallego Maestro, Jesús ; Pérez González, Pablo Guillermo ; Cardiel López, Nicolás ; Zamorano Calvo, Jaime ; Guzmán, R. ; González, A. ; Gruel, N. | Universidad Nacional Autónoma México, Instituto Astronomía | 2013Our main objective is to determine what kind of galaxies dominate the cosmic SFR density at z~2. Our sample consists of 24 galaxies in Chandra Deep Field South, a unique field for the study of galaxy evolution (12 observed with GNIRS/GEMINI and [...]texto impreso
García Bedregal, A. ; Cardiel López, Nicolás ; Aragón Salamanca, A. ; Merrifield, M. R. | Wiley | 2011-08We present absorption-line index gradients for a sample of S0 galaxies in the Fornax cluster. The sample has been selected to span a wide range in galaxy mass, and the deep FORS2 spectroscopy on the VLT allows us to explore the stellar populatio[...]texto impreso
Mármol Queraltó, Esther ; 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 | Cambridge Univ. Press | 2009-08A full understanding of the physical properties of integrated stellar systems demands a multiwavelength approach since each spectral window shows us the contribution of different types of stars. However, most of the observational effort in stell[...]texto impreso
Sánchez Blázquez, P. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; González, J. J. | EDP Sciencies | 2006-10This paper commences a series devoted to the study of the stellar content of early-type galaxies. The goal of the series is to set constraints on the evolutionary status of these objects. Methods. In this paper we describe the details of the gal[...]texto impreso

Methods. We present line-strength gradients f[...]texto impreso
Cardiel López, Nicolás ; Jiménez Esteban, F. M. ; Alacid, J. M. ; Solano, E. ; Aberasturi, M. | Wiley | 2011-11The observation of blank fields, regions of the sky devoid of stars down to a given threshold magnitude, constitutes one of the typical important calibration procedures required for the proper reduction of astronomical data obtained in imaging m[...]texto impreso

W. ; Matkovic, A. ; Vass, I. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás | Astronomical Soc Pacific | 2003We present preliminary results of an extensive study of the fundamental properties of dwarf elliptical galaxies (dEs) in the Coma cluster. Our study will combine HST surface photometry with ground-based UBRIJK photometry and optical spectroscopy[...]texto impreso
Bedregal, A. G. ; Aragón Salamanca, A. ; Merrifield, M. R. ; Cardiel López, Nicolás | Wiley | 2008-06-21Using high signal-to-noise ratio VLT/FORS2 long-slit spectroscopy, we have studied the properties of the central stellar populations and dynamics of a sample of S0 galaxies in the Fornax cluster. The central absorption-line indices in these gala[...]
