ADC_Keywords: Interstellar medium ; Galaxies, nearby ; Ultraviolet ; Infrared sources Keywords: galaxies: interactions - galaxies: ISM - galaxies: starburst - ISM: structure Abstract: Far-ultraviolet to far-infrared images of the nearby galaxy NGC 5194 (M51a), from a combination of space-based (Spitzer, GALEX, and Hubble Space Telescope) and ground-based data, are used to investigate local and global star formation and the impact of dust extinction. The Spitzer data provide unprecedented spatial detail in the infrared, down to sizes 500 pc at the distance of NGC 5194. The multiwavelength set is used to trace the relatively young stellar populations, the ionized gas, and the dust absorption and emission in HII-emitting knots, over 3 orders of magnitude in wavelength range.

Note (1): Identification of the HII knots for which photometry has been measured in 13" diameter apertures. The ID format XX-YY identifies the background region (XX) where the aperture is located and an internal progressive number (YY) for the aperture. Note (2): In units of erg/s. Logarithm of the luminosities in the FUV (1529Å) and NUV (2312Å) from GALEX, U, B, and Hα (0.6563µm) from ground-based images, Paα(1.8756µm) from HST NICMOS, and 8 and 24µm from Spitzer IRAC and MIPS. Stellar continuum luminosities are given as λL(λ). The central wavelengths of the U and B filters are 0.3463µm and 0.4312µm, respectively. Stellar and ionized gas luminosities have been corrected for the Galactic foreground extinction E(B-V)MW=0.037.
