Abstract:	We study the environments of 49 WISE/NVSS-selected hyper-luminous, heavily obscured, z∼2 quasars. The fields were observed with ALMA in Band 7. We find that 17 of the 49 WISE/NVSS sources show companion sub-mm galaxies within the ALMA primary beam. The 870 μm source counts measured from these fields are >10 times larger than expectations for unbiased regions. This suggests that these red WISE/NVSS quasars reside in highly clustered environments.
