There is evidence at low redshift of an increase in the AGN fraction of galaxies in close pairs. This naturally suggests a possible relation between galaxy mergers or interactions and AGN activity, but there seems to be no excess of disturbed morphologies in AGN when compared with quiescent galaxies, even to z~2. To investigate this apparent discrepancy, I utilize HST/WFC3 Infrared Grism observations in the CANDELS GOODS-S and Ultra Deep Survey fields to create a NIR redshift catalog with the intent of calculating the fraction of  X-Ray and IR selected AGN in close pairs out to z~2.
