Beginning of ReadMe : J/ApJ/658/1006 Radial profiles for 161 face-on spirals (Munoz-Mateos+, 2007) ================================================================================ Specific star formation rate profiles in nearby spiral galaxies: quantifying the inside-out formation of disks. Munoz-Mateos J.C., Gil De Paz A., Boissier S., Zamorano J., Jarrett T., Gallego J., Madore B.F. <Astrophys. J., 658, 1006-1026 (2007)> =2007ApJ...658.1006M ================================================================================ ADC_Keywords: Galaxies, nearby ; Galaxies, photometry ; Ultraviolet Keywords: atlases - galaxies: photometry - galaxies: stellar content - infrared: galaxies - ultraviolet: galaxies Abstract: We present specific star formation rate (sSFR) radial profiles for a sample of 161 relatively face-on spiral galaxies from the GALEX Atlas of Nearby Galaxies. The sSFR profiles are derived from GALEX and 2MASS (FUV-K) color profiles after a proper SFR calibration of the UV luminosity and K-band mass-to-light ratio are adopted. The (FUV-K) profiles were first corrected for foreground Galactic extinction and later for internal extinction using the ratio of the total-infrared (TIR) to FUV emission. For those objects where TIR-to-FUV ratio radial profiles were not available, the (FUV-NUV) color profiles were used as a measure of the UV slope. The sSFR radial gradients derived from these profiles allow us to quantify the inside-out scenario for the growth of spiral disks for the first time in the local universe. Description: We have compiled a sample of 161 galaxies from the GALEX Ultraviolet Atlas of Nearby Galaxies (Gil de Paz et al. 2007, Cat. J/ApJS/173/185) on the basis of two main selection criteria: morphological type and inclination.
