Gil de Paz, Armando ; Silich, S. A. ; Madore, B. F. ; Sánchez Contreras, C. ; Zamorano Calvo, Jaime ; Gallego Maestro, Jesús | Univ. Chicago Press | 2002-07-10We have mapped the ^(12)CO J = 1-0 and J = 2-1 line emission in Markarian 86, one of the most metal- deficient blue compact dwarf galaxies so far detected in ^(12)CO. The ^(12)CO emission is distributed in a horseshoelike structure that follows [...]texto impreso

C. | American Astronomical Society | 2005-07-01Recent far-UV (FUV) and near-UV (NUV) observations of the nearby galaxy NGC 4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended UV disk reaching to 4 times the optical radius of the galaxy. The UV-to-optical color[...]texto impreso
Gil de Paz, Armando ; Madore, B. F. ; Noeske, K. ; Cairós, L. M. ; Papaderos, P. ; Silich, S. A. | American Astronomical Society | 2003-10-20We report the discovery of a double ring of emission-line regions around the nucleus of the blue compact dwarf galaxy Mrk 409 as seen by deep, ground-based H? images. Echelle spectroscopy obtained at Magellan I with MIKE shows the presence of io[...]texto impreso
Roussel, H. ; Gil de Paz, Armando ; Seibert, M. ; Helou, G;, G. ; Madore, B. F. ; Martín, C. | American Astronomical Society | 2005-10-10We investigate the possible origin of the strong radial gradient in the ultraviolet-to-infrared ratio in the nearby late-type spiral galaxy NGC 300 and emphasize the importance of local variations in the geometry of the interstellar medium, conc[...]texto impreso
We have derived the uncertainties to be expected in the derivation of galaxy physical properties (star formation history, age, metallicity, and reddening) when comparing broadband photometry to the predictions of evolutionary synthesis models. W[...]texto impreso

F. ; Bendo, G. ; Boselli, A. ; Buat, V. ; Calzetti, D. ; Moustakas, J. ; Kennicutt, R. C. Jr. | American Astronomical Society | 2009-10-01We present ultraviolet through far-infrared (FIR) surface brightness profiles for the 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). The imagery used to measure the profiles includes Galaxy Evolution Explorer UV data, optica[...]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
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
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[...]texto impreso

C. | American Astronomical Society | 2006-01-20We analyze the dust attenuation properties of a volume-limited, optically selected sample of normal star-forming galaxies in nearby clusters as observed by GALEX. The internal attenuation is estimated using three independent indicators, namely, [...]
