One of the two sources is the best candidate to date for being a recoiling super-massive black hole (SMBH) with both spectroscopic and imaging signatures, in a recently merged system. CID-42 is a possible ??Rosetta stone?? for the study of SMBH mergers that are believed to occur during galaxy-galaxy mergers. Is CID-42 (1) a GW recoiling SMBH from a recent merger or (2) a slingshot recoiling SMBH in a triple SMBH system? HRC imaging will decide clearly. ------------------------------------------------------------------------------------ Observations Description ------------------------ STIS long-slit spectroscopy (G750L) observation.
