Pérez González, Pablo Guillermo ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús ; Gil de Paz, Armando | EDP Sciences | 2000-02We present Johnson B CCD photometry for the whole sample of galaxies of the Universidad Complutense de Madrid (UCM) Survey Lists I and II. They constitute a well-defined and complete sample of galaxies in the Local Universe with active star form[...]texto impreso
We consider a Markov decision process for an MX/M/1 queue that is controlled by batches of negative customers. More specifically, we derive conditions that imply threshold-type optimal policies, under either the total discounted cost criterion o[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel ; Satalecka, Konstanzja ; Scapin, Valeria | EDP Sciences | 2012-04We use 73 h of stereoscopic data taken with the MAGIC telescopes to investigate the very high-energy (VHE) gamma-ray emission of the Crab pulsar. Our data show a highly significant pulsed signal in the energy range from 50 to 400 GeV in both the[...]texto impreso
Vitores, A. G. ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Gallego Maestro, Jesús ; Alonso, O. | EDP Sciences | 1996-12We present the results of Thuan & Gunn r CCD imaging observations of the Universidad Complutense de Madrid (UCM) sample of emission-line galaxies (ELGs) selected by the presence of H_? emission in low resolution objective-prism spectra. In this [...]texto impreso

Klutsch, Alexis ; Freire Ferreros, R. ; Guillout, P. ; Frasca, A. ; Marilli, E. ; Montes Gutiérrez, David | EDP Sciences | 2014-07Context. Over the last century, the overdensities in the velocity distributions of nearby stars were attributed to stellar kinematic groups or moving groups. Although their reality was initially questioned, their existence is now supported by a [...]texto impreso
Cardiel López, Nicolás ; Gorgas García, Francisco Javier ; Cenarro, J. ; González, J. J. | EDP Sciences | 1998-02We present a new set of accurate formulae for the computation of random errors in the measurement of atomic and molecular line-strength indices. The new expressions are in excellent agreement with numerical simulations. We have found that, in so[...]texto impreso
Frasca, A. ; Guillout, P. ; Klutsch, A. ; Freire Ferrero, R. ; Marilli, E. ; Biazzo, K. ; Gandolfi, D. ; Montes Gutiérrez, David | EDP Sciences | 2018-05-04Context. Star formation in the solar neighborhood is mainly traced by young stars in open clusters, associations, and in the field, which can be identified, for example, by their X-ray emission. The determination of stellar parameters for the op[...]texto impreso
You The Air Microwave Yield (AMY) experiment investigate the molecular bremsstrahlung radiation emitted in the GHz frequency range from an electron beam induced air-shower. The measurements have been performed at the Beam Test Facility (BTF) of [...]texto impreso

Vázquez Peñas, José Ramón ; Rosado Vélez, Jaime ; García Pinto, Diego ; Arqueros Martínez, Fernando | EDP Sciences | 2013The fluorescence yield data used for shower reconstruction in the Auger, HiRes and TA experiments are different, not only in the overall absolute value but also in the wavelength spectrum and the various atmospheric dependencies. The effect on t[...]texto impreso
A novel method for direct electronic "fast-timing" lifetime measurements of nuclear excited states via gamma-gamma coincidences using an array equipped with N very fast high-resolution LaBr3(Ce) scintillator detectors is presented. The generaliz[...]texto impreso
Borlaff, Alejandro ; Trujillo, Ignacio ; Román, Javier ; Beckman, John E. ; Eliche Moral, M. Carmen ; Infante Sáinz, Raúl ; Lumbreras Calle, Alejandro ; Takuro Sato Martín de Almagro, Rodrigo ; Gómez Guijarro, Carlos ; Cebrián, María ; Dorta, Antonio ; Cardiel López, Nicolás ; Akhlaghi, Mohammad ; Martínez Lombilla, Cristina | EDP Sciences | 2019-01-21Context. The Hubble Ultra Deep field (HUDF) is the deepest region ever observed with the Hubble Space Telescope. With the main objective of unveiling the nature of galaxies up to z ? 7?8, the observing and reduction strategy have focused on the [...]texto impreso
At the PF1B cold neutron beam line at the Institut Laue Langevin, the EXILL array consisting of EXOGAM, GASP and ILL-Clover detectors was used to perform (n,gamma) measurements at very high coincidence rates. About ten different reactions were m[...]texto impreso
Reglero, V. ; Fernández Figueroa, María José ; Giménez, A. ; Castro Rubio, Elisa de ; Fabregat, J. ; Cornide Castro-Piñeiro, Manuel ; Armentia, J. E. | EDP Sciences | 1991-06A detailed study of the system V772 Her = HD 165590 = ADS 11060 AB is presented. The three identified components are found to be late type stars close to the zero-age main sequence with high rotational velocities. Spectroscopic observations allo[...]texto impreso
This paper is the first of a series whose aim is to perform a systematic study of A-type supergiant atmospheres and winds. Here we present a spectral atlas of 41 A-supergiants observed by us in high and medium resolution in the visible asd ultra[...]texto impreso
Sánchez, Néstor ; Gómez de Castro, Ana Inés ; López-Martinez, Fátima ; López-Santiago, Javier | EDP Sciences | 2014-12We analyze 359 ultraviolet tiles from. the All Sky Imaging Survey of the space mission GALEX covering roughly 400 square degrees toward the Orion star-forming region. There are a total of 1 555 174 ultraviolet sources that were cross-matched wit[...]
