In order to understand the evolution of a galaxy, it is essential to determine its star formation properties as well as its growth in stellar mass over cosmic timescales. WISE, the all-sky, mid-infrared survey, affords us the opportunity to investigate both these parameters for galaxies with a wide range of morphologies, activity types, and stellar masses.
In this talk, I will discuss our investigation of the two WISE star formation indicators at 12 (W3) and 22 (W4) microns, using ancillary data from the Spitzer Infrared Nearby Galaxy Survey (SINGS).
I will present results on the reliability of W3 as a star formation indicator, introduce a new star formation rate (SFR) relation based on our analysis, as well as a comparison of existing SFR relations to our new relation. I will also comment on future work to be done on the spatially detailed, albeit qualitative, analysis of a few selected well-resolved galaxies to investigate local star formation processes.
