“Hunting Coreshine with Spitzer” (P.I. R. Paladini) is the largest (165.5hrs) approved Cycle-8 Warm Spitzer proposal in the Galactic science category. Goal of the 3.6 mm and 4.5 mm observations of 90 cold cores randomly selected from the Planck Early Cold Cores Catalog is an unbiased investigation of the coreshine effect which is thought to provide direct evidence for grain growth in cold, dense environments. A preliminary results indicates that ~50% of the sources are characterized by coreshine. In Cycle 9, we requested an additional 42.5 hrs for a deep 4.5 mm follow-up of 10 sources included in the original sample. The analysis on the data – currently on-going – shows a positive detection for > 70% of the sources.
