New Galaxy Evolution Explorer (GALEX) observations have detected significant far-UV (FUV; 1530 Å) and near-UV (NUV; 2310 Å) emission from stellar substructures within the tidal tails of four ongoing galaxy mergers. The UV-bright regions are opti[...]texto impreso
The recent star formation (SF) in the early-type spiral galaxy M81 is characterized using imaging observations from the far-ultraviolet to the far-infrared. We compare these data with models of the stellar, gas, and dust emission for subgalactic[...]texto impreso
The mechanism causing breaks in the radial surface brightness distribution of spiral galaxies is not yet well known. Despite theoretical efforts, there is not a unique explanation for these features and the observational results are not conclusi[...]texto impreso
We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 ?m images from the Spitzer Survey of Stellar Structure in Galaxies. Our model fit includes up to four components (bulge, disk, bar, and [...]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, [...]texto impreso
Lee, Janice C. ; Gil de Paz, Armando ; Tremonti, Christy ; Kennicutt, Robert | Astronomical Society of the Pacific | 2011A great deal of our understanding of star formation in the local universe has been built upon an extensive foundation of H? observational studies. However, recent work in the ultraviolet (UV) with GALEX has shown that star formation rates (SFRs)[...]texto impreso

M. ; Sohn, Y. J. | American Astronomical Society | 2005-08-10We study the UV properties of a volume-limited sample of early-type galaxies in the Virgo Cluster combining new GALEX far-ultraviolet (1530 Å) and near-ultraviolet (2310 Å) data with spectrophotometric data available at other wavelengths. The sa[...]texto impreso
García Vargas, M. L. ; Pérez Calpena, A. ; Gallego Maestro, Jesús ; Gil de Paz, Armando ; Sánchez Blanco, E. ; Martínez Delgado, I. ; Maldonado Medina, M. ; Zamorano Calvo, Jaime | Spie-Int Soc Optical Engineering | 2012The goal of VIENTOS project is to analyze pupil innovative systems that could be used in the new generation of instruments for the large telescopes. This study tries to identify the current scientific needs, to understand why some of them have n[...]texto impreso
Stellar bars can lead to gas inflow toward the center of a galaxy and stimulate nuclear star formation. However, there is no compelling evidence on whether they also feed a central supermassive black hole: by measuring the fractions of barred ac[...]
