Getting WISE on Star Formation

Abstract

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. <i>WISE</i>, 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 <i>Spitzer</i> 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.
