Star Formation and Far-Infrared Emission in Non-Seyfert Markarian Galaxies

Kurt Alan Roettiger

ABSTRACT

The recent star formation and far-infrared (FIR) emission of a sample of non-Seyfert Markarian galaxies will be examined using recently obtained H-alpha data and FIR data from the Infrared Astronomical Satellite (IRAS). In determining the relationship between the non-Seyfert Markarian sample and a sample of "normal" field galaxies, I will determine if Huchra's (1977) conclusion that they are only a subset of field galaxies extends to H-alpha and FIR emission. I will also, by means of comparing the H-alpha and FIR emission, attempt to evaluate the FIR surface brightness and FIR spectral index as star formation indicators. Finally, I will discuss why I believe these FIR quantities are linked to recent star formation, but not so exclusively that they can be considered sensitive indicators of recent star formation.
