F. ; Zamorano Calvo, Jaime | Wiley | 2010-02-21The kinematic properties of the ionized gas of local luminous compact blue galaxy NGC 7673 are presented using three-dimensional data taken with the PPAK integral field unit at the 3.5-m telescope in the Centro Astronomico Hispano Aleman.

Rodríguez Espinosa, J.M. ; Mas-Hesse, J.M. ; Salvador-Solé, E. ; Calvi, R. ; Manrique, A. ; Chanchaiworawit, K. ; Guzmán, R. ; Gallego Maestro, Jesús ; Herrero, A. ; Marín Franch, A. | Oxford University Press. | 2020-06We show herein that a proto-cluster of Ly ? emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum photons. We start from the Ly ? fluxes measured in the spectra of the sources detected[...]texto impreso
Domínguez Palmero., L. ; Balcells, M. ; Erwin, P. ; Prieto, M. ; Cristobal Hornillos, D. ; Eliche Moral, María del Carmen ; Guzmán, R. | EDP Sciencies | 2008-09Context. Analysis of bulges to redshifts of up to z?1 have provided ambiguous results as to whether bulges as a class are old structures akin to elliptical galaxies or younger products of the evolution of their host disks. Aims. We aim to define[...]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
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
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
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
Villar, V. ; Guzmán, R. ; Gallego Maestro, Jesús ; Pérez González, Pablo Guillermo ; Zamorano Calvo, Jaime | Universidad Nacional Autónoma México, Instituto Astronomía | 2013We analyze the properties of star forming regions in a sample of star forming galaxies at z = 0.84. Star forming regions are extracted from B band ACS-HST images. Previously we have substracted a model of the galaxy, fitting a bulged+disk model [...]texto impreso

The goal of the project is to detect very distant galaxies at the dawn of the Universe. These remote and [...]texto impreso

Universidad Nacional Autónoma de México | 2003As a part of our collaboration in the COSMOS Project, devoted to the characterization of galaxies during the ep o c h of maximum star formation in the history of the Universe, we have carried out a deep photometric survey covering about 380 arcm[...]texto impreso

The index-sigma relations for our sample, including galaxies with sigmatexto impreso
Eliche Moral, María del Carmen ; Prieto, M. ; Gallego Maestro, Jesús ; Barro, Guillermo ; Zamorano Calvo, Jaime ; López Sanjuan, C. ; Balcells, M. ; Guzmán, R. ; Muñoz Mateos, J. C. | EDP Sciencies | 2010-09Context. Several studies have tried to ascertain whether the increase in abundance of the early-type galaxies (E-S0a's) with time is mainly due to major mergers, but have reached opposite conclusions. Aims. We have tested it directly through sem[...]texto impreso
Barro, G. ; 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 | EDP Sciencies | 2009-01Context. The galaxy number counts has been traditionally used to test models of galaxy evolution. However, the origin of significant differences in the shape of number counts at different wavelengths is still unclear. By relating the most remark[...]
