For each example target galaxy below, you are provided with:
(1) Link to image of R (stars) and Hα (star formation)
obtained at Kitt Peak
(2) links to public database images
and the NED.
Use this information to understand why we want to reobserve these and similar sources.
For comparison, check out a spiral galaxy with "normal" star formation and an ALFALFA detection:

  DR7Navigate
  DR9Navigate
  SkyView.03
  SkyView.10
  DSS2red.03
  DSS2blu.03
  DSS2red.10
  DSS2blu.10
  NED1
  NED10
  ALFALFA Spectrum
Question: Describe locations of star formation with respect to the distribution of stars for this "normal" galaxy. Describe the spectrum.
