The mid-infrared emission peaks at 24 days after explosion at a few times 10^7 Lsun, and decays more slowly than the visible-light bolometric luminosity. The infrared color temperature cools for the first 90 days and then is constant. Simple numerical models of a thermal echo can qualitatively reproduce the early behavior. At late times, the mid-IR light curve cannot be explained by a simple thermal echo model, suggesting additional dust heating or line emissio","authors_text":"Avishay Gal-Yam, Eran O.
