The ultraviolet-to-radio continuum spectral energy distributions are presented for all 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). ... These results suggest that the star formation history may be the dominant regulator of the broadband spectral variations between galaxies. Finally, a new discovery shows that the 24 ЮМm morphology can be a useful tool for parameterizing the global dust temperature and ultraviolet extinction in nearby galaxies. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

For example, among the Milky Way's dE companions we see systems with dominant old populations, systems with minor intermediate-age (age ~ 2 to 10 Gyr) components, and systems where the intermediate-age component dominates the old stars. ... This variety of star formation histories is not restricted to the Galaxy's companions. ... To make progress in understanding the processes that govern dwarf galaxy evolution, we need to study systems beyond the Local Group. ...
