Re:IC 3949
This galaxy has an exponential profile and blue optical and NUV-optical colors
indicative of star formation. However, its nuclear spectrum is mainly that of an
older stellar population but with weak H{alpha} and [N II] emission lines. The
equivalent width of the H{alpha} line is less than that of the [N II],
suggestive of an active nucleus. Correcting the H{alpha} equivalent width for
underlying stellar absorption, the [N II]/H{alpha} ratio is very close to 0.6,
the value frequently used as the division between star-forming galaxies and
AGNs. The synthesized spectrum that best fits the photometry is that of a
starburst. We interpret this galaxy as having its radio emission dominated by
star formation in its disk with a more quiescent central bulge; visual
inspection of the SDSS color image backs this interpretation.
