We present a library of Utrecht echelle spectrograph (UES) observations of a sample of F, G, K and M field dwarf stars covering the spectral range from 4800 Å to 10600 Å with a resolution of 55000. These spectra include some of the spectral line[...]texto impreso
Gil de Paz, Armando ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús ; Domínguez, F. de B. | EDP Sciences | 2000-09We have obtained optical (BVR, [O III]? 5007 Å and H_?), near infrared (JHK) imaging and long-slit optical spectroscopy for the Blue Compact Dwarf galaxy Mrk 86 (NGC 2537). In this paper, the first of two, we present optical-near-infrared colors[...]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 ; Scapin, Valeria | EDP Sciences | 2012-06The blazar Markarian 421 is one of the brightest TeV gamma-ray sources of the northern sky. From December 2007 until June 2008 it was intensively observed in the very high energy (VHE, E > 100 GeV) band by the single-dish Major Atmospheric Gamm[...]texto impreso
Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Sanz Forcada, J. | EDP Sciences | 1997-10This is the first paper of a series aimed at studying the chromosphere of active binary systems using the information provided for several optical spectroscopic features. Simultaneous H_?, Na I D_1, D_2, and He I D_3 spectroscopic observations a[...]texto impreso

We present generalized Green-Kubo expressions for thermal transport coefficients mu in non-conservative fluid-type systems, of the generic form mu = mu(infinity)+ integral(o)(infinity) dtV(-1) [I-epsilon exp[tL] I](0), where exp[tL] is a pseudo-[...]texto impreso
Gallego Maestro, Jesús ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Alonso, O. ; Vitores, A. G. | EDP Sciences | 1996-12Spectroscopic observations for the full sample of Her emission-line galaxy candidates (ELGs) from the Universidad Complutense de Madrid objective-prism survey Lists 1 and 2 have been obtained in order to investigate fully the properties of the s[...]texto impreso
A phenomenological and Newtonian model is proposed to explain the recent observed cosmological variation of the fine-structure constant as an effect of the quantum vacuum, assuming a at universe with cosmological Lambda constant in the cases (Om[...]texto impreso
Rosado Vélez, Jaime ; Gallego, P. ; García Pinto, Diego ; Blanco Ramos, Francisco ; Arqueros Martínez, Fernando | EDP Sciences | 2013-02-13The uncertainty in the absolute value of the air-fluorescence yield still puts a severe limit on the accuracy in the primary energy of ultra-high-energy cosmic rays. The precise measurement of this parameter in laboratory is in turn conditioned [...]texto impreso
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

Our data show a highly significant pulsed signal in the energy range from 50 to 400 GeV in both the[...]texto impreso
Vitores, A.
