Ly alpha nebulae are giant (similar to 100 kpc), glowing gas clouds in the distant universe. The origin of their extended Ly alpha emission remains a mystery. Some models posit that Ly alpha emission is produced when the cloud is photoionized by UV emission from embedded or nearby sources, while others suggest that the Ly alpha photons originate from an embedded galaxy or active galactic nucleus (AGN) and are then resonantly scattered by the cloud. At least in the latter scenario, the observed Ly alpha emission will be polarized. To test these possibilities, we are conducting imaging polarimetric observations of seven Ly alpha nebulae. Here we present our results for LABd05, a cloud at z = 2.656 with an obscured, embedded AGN to the northea...
