Alonso, O. ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Gallego Maestro, Jesús ; Vitores, A.G. | Kluwer Academic Publ. | 1994The most unambiguous way to discover new emission-line galaxies (ELGs) is directly by the presence of their lines, using objective-prism plates of adequate resolution. The first survey using this technique was developed by Smith in 1975 with the[...]texto impreso
Evolutionary population synthesis models with different metallicities have been computed in order to interpret the observed Mg_2 and H?, line-strength indices in old stellar populations. Both indices are found to be quite insensitive to change[...]texto impreso
Fernández Figueroa, María José ; Montesinos, B. ; Castro Rubio, Elisa de ; Rego Fernández, Manuel ; Giménez, A. ; Reglero, V. | EDP Sciencies | 1986-11We report here new Ca II H and K emission line fluxes and equivalent widths for seven RSCVn binary systems, observed at several orbital phases. All the stars show enhanced chromospheric activity. With information from available spectra, an in d[...]texto impreso
Castro Rubio, Elisa de ; Fernández Figueroa, María José ; Rego Fernández, Manuel ; Ponz, D. | EDP Sciencies | 1981Far ultraviolet emission lines in a sample of seven stars of spectral type later than F5 and different luminosity class have been analyzed to calculate the electron density and pressure in the formation region of the lines. Three different metho[...]texto impreso
Fernández Figueroa, María José ; Rego Fernández, Manuel ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 1980The structure of the outer stellar regions is investigated for four G type dwarfs observed with the IUE satellite. Line fluxes of the Si II lines at 1817 Å, 1808 A, and 1309 Å and Si III at 1206 Å are used to obtain temperatures and electronic [...]texto impreso
Alonso, O. ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Gallego Maestro, Jesús | EDP Sciences | 1995-10A full set of algorithms for the automatic analysis of low-resolution objective-prism spectra has been developed with the aim of finding new emission-line galaxies (ELGs) candidates from the Universidad Complutense de Madrid (UCM) survey prism p[...]texto impreso
Fernández Villacañas, J. L. ; Rego Fernández, Manuel ; Cornide Castro-Piñeiro, Manuel | IOP publishing ltd | 1990-06An intermediate-dispersion abundance analysis has been carried out on a sample of 21 barium and 14 comparison stars. The excess of barium over iron has been used as the most representative indicator of peculiarity. These excesses are higher in t[...]texto impreso
Gallego Maestro, Jesús ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Vitores, A. G. | EDP Sciencies | 1994-10We analyze a rather interesting galaxy discovered during the UCM survey for new H? emission-line galaxies. The new galaxy UCM 2329+2500 presents a compact core that hosts a Seyfert 1 nucleus. The spectrum of the Seyfert nucleus presents broad co[...]texto impreso
Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Rego Fernández, Manuel | EDP Sciencies | 1983Ultraviolet emissions of ?Cet, ?Pav, and 61 Cyg A have been analysed to determine the structure of their outer atmospheres. Emission line fluxes are used to find the emission measure distributions. Using two boundary values of the electron press[...]texto impreso
Rego Fernández, Manuel ; Cordero Gracia, M. ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús | IOP publishing ltd | 1993-02We present the results of IRAS observations of the UCM (Universidad Complutense de Madrid) sample of emission-line galaxies, which have been selected from wide-dispersion H_? objective-prism plates. These data are intended to provide a convenien[...]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
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
Vitores, A. G. ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Alonso, O ; Gallego Maestro, Jesús | EDP Sciences | 1996-07We 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
Rego Fernández, Manuel ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús ; Vitores, A. G. | EDP Sciencies | 1994-01The galaxy UCM 2303 + 1702, not previously known, was identified during the Universidad Complutense de Madrid (UCM) objective-prism survey. The optical spectrum displays emission lines with a blueward asymmetry. Forbidden lines cover a wide rang[...]texto impreso
Gallego Maestro, Jesús ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Vitores, A. G. | American Astronomical Society | 1997-02-01A spectroscopic analysis of the entire sample of Ha emission-line galaxies (ELGs) contained in lists 1 and 2 of the Universidad Complutense de Madrid (UCM) objective-prism survey is presented. A significant fraction (59%) of star-forming galaxie[...]
