The Galaxy Evolution Explorer (GALEX) Nearby Galaxies Survey is providing deep far-UV and near-UV imaging for a representative sample of galaxies in the local universe. We present early results for M51 and M101, from GALEX UV imaging and Sloan D[...]texto impreso
Ultraviolet imaging with the Galaxy Evolution Explorer (GALEX) has revealed an extensive sample of UV-bright stellar complexes in the extreme outer disk of M83, extending to about 4 times the radius at which the majority of H II regions are dete[...]texto impreso
Rodríguez Muñoz, Lucía ; Gallego Maestro, Jesús ; Pacifici, Camilla ; Tresse, Laurence ; Charlot, Stéphane ; Gil de Paz, Armando ; Barro, Guillermo ; Villar, Víctor | IOP Publishing | 2015-01-20The epoch when low-mass star-forming galaxies (LMSFGs) form the bulk of their stellar mass is uncertain. While some models predict an early formation, others favor a delayed scenario until later ages of the universe. We present constraints on th[...]texto impreso
With the aim of constructing accurate two-dimensional maps of the stellar mass distribution in nearby galaxies from Spitzer Survey of Stellar Structure in Galaxies 3.6 and 4.5 ?m images, we report on the separation of the light from old stars fr[...]texto impreso
We present a new approach for estimating the 3.6 ?m stellar mass-to-light (M/L) ratio ?_3.6 in terms of the [3.6]-[4.5] colors of old stellar populations. Our approach avoids several of the largest sources of uncertainty in existing techniques u[...]texto impreso

M. ; Schiminovich, D. ; Seibert, M.;, M. ; Wyder, T. | Astronomical Society of the Pacific (ASP) | 2008We describe HST imaging of recent star formation complexes located in the extended UV disk (XUV-disk) component of NGC 5236 (M 83), NGC 5055 (M 63), and NGC 2090. Photometry in four FUV-visible bands permits us to constrain the type of resolved [...]texto impreso
Gil de Paz, Armando ; Chotia, A. ; Marechal, E. ; Pedri, P. ; Vernac, L. ; Gorceix, O. ; Laburthe-Tolra, B. | American Physical Society | 2013-05-31We study dipolar relaxation of a chromium Bose-Einstein condensate loaded into a three-dimensional (3D) optical lattice. We observe dipolar relaxation resonances when the magnetic energy released during the inelastic collision matches an excitat[...]texto impreso
Tulloch, S. ; Gil de Paz, Armando ; Gallego Maestro, Jesús ; Zamorano Calvo, Jaime ; Tapia, C. | Spie-Int Soc Optical Engineering | 2012A CCD test-bench has been built at the Universidad Complutense's LICA laboratory. It is initially intended for commissioning of the MEGARA(1) (Multi-Espectrografo en GTC de Alta Resolucion para Astronomia) instrument but can be considered as a g[...]texto impreso
We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Here we compare GALEX UV and visible-NIR images of 189 nearby (Dtexto impreso
Pérez González, Pablo Guillermo ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús ; Aragón Salamanca, A. ; Gil de Paz, Armando | American Astronomical Society | 2003-07-10We present a photometric study of the Halpha emission in the Universidad Complutense de Madrid (UCM) Survey galaxies. This work complements our previously published spectroscopic data. We study the location of the star-forming knots, their inten[...]texto impreso

We carry out a detailed 2-D study of the ionised gas in the local universe galaxy UGC 9837. In nearby galaxies, like the galaxy in question here, the spatial distribution of the physical properties can be studied in detail, providing be[...]texto impreso
Muñoz Mateos, J. C. ; Gil de Paz, Armando ; Boissier, S. ; Zamorano Calvo, Jaime ; Jarrett, T. ; Gallego Maestro, Jesús ; Madore, B. F. | American Astronomical Society | 2007-04-01We present specific star formation rate (sSFR) radial profiles for a sample of 161 relatively face-on spiral galaxies from the GALEX Atlas of NearbyGalaxies. The sSFR profiles are derived from GALEX and 2MASS (FUV-K) color profiles after a prope[...]texto impreso
We present a catalogue and images of visually detected features, such as asymmetries, extensions, warps, shells, tidal tails, polar rings, and obvious signs of mergers or interactions, in the faint outer regions (at and outside of R_25) of nearb[...]texto impreso
Madore, B. F. ; Boissier, S. ; Gil de Paz, Armando ; Nelson, E. ; Petrillo, K. | Astronomical Society of the Pacific | 2007We present recent results from several on-going studies: The first addresses the question of gas-density thresholds for star formation, as probed by the outer disks of normal nearby galaxies. The second concerns the observational evidence for th[...]
