@article{Komossa2008ARS, title={A Recoiling Supermassive Black Hole in the Quasar SDSS J092712.65+294344.0?}, author={Stefanie Komossa and H. Y. Zhou and H. L. Lu}, journal={The Astrophysical Journal Letters}, year={2008}, volume={678}, pages={L81 - L84} }
We present SDSS J092712.65+294344.0 as the best candidate to date for a recoiling supermassive black hole (SMBH). SDSS J0927+2943 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−1 relative to the set of narrow emission lines. This observation is most naturally explained if the SMBH was ejected from the core of…
