ORIGIN OF 12 μm EMISSION ACROSS GALAXY POPULATIONS FROM<i>WISE</i>AND SDSS SURVEYS
We cross-matched Wide-field Infrared Survey Explorer sources brighter than 1 mJy at 12 μm with the Sloan Digital Sky Survey galaxy spectroscopic catalog to produce a sample of ∼105 galaxies at 〈z〉 = 0.08, the largest of its kind. This sample is dominated (70%) by star-forming (SF) galaxies from the …
