Recent numerical relativity simulations of coalescing, binary supermassive black holes {SMBHs} predict kick velocities as large as several thousand km/s due to anisotropic emission of gravitational waves. We have recently discovered the best candidate to date for such a recoiling SMBH, the quasar SDSS0927+2943. It shows an exceptional optical emission-line spectrum with two sets of emission lines; one set of very narrow emission lines, and a second set of broad Balmer and broad high-ionization forbidden lines which are blueshifted by 2650 km/s relative to the narrow emission lines. This is the predicted spectroscopic signature of a SMBH recoiling from the core of its host galaxy, carrying with it the broad-line gas while leaving behind the bulk of the narrow-line gas. We apply for HST imaging in two filters for two orbits each in order to confirm the recoil model by detecting the host galaxy of the SMBH and measuring the angular offset of the recoiling SMBH from the host galaxy core; and determining, if possible, the morphology of the host galaxy in order to constrain its merger history. Confirmation of the SMBH ejection model for SDSSJ0927+2943 with HST will show decisively that kicks large enough to remove SMBHs completely from their host galaxies do occur, a result that would have profound implications for models of SMBH evolution and galaxy assembly and for numerical relativity.;
