Title: Investigating the Connection Between Green Fuzzy Emission and Molecular Outflows
Abstract: ?Green Fuzzies? are extended sources with enhanced emission in Spitzer?s 4.5um IRAC filter (which people generally false-color as green when making 3-color images from Spitzer data). They have recently been linked to outflows from massive young stellar objects. It has been speculated that the enhanced emission in green fuzzies is due to CO in these outflows emitting at 4.6um.We propose NIRI long slit K, L, and M-band spectroscopic observations of two bright green fuzzies that have prominent mm CO outflows co-located with the green fuzzy emission. The proposed observations will allows us to determine if CO emission in the NIR can be a major contributor to the 4.5um enhancement in green fuzzies. More importantly, the proposed observations will also allow us to determine the physical conditions of the gas exciting the green fuzzy emission, and compare them to models that have been recently proposed to explain green fuzzy emission. The observations, reduction, and interpretation are very simple and straightforward. The sources are expected to be bright in their line emission, and observations can be done in less-than-optimal conditions.
