Displacement of black hole in M87
Listed in IVOA Registry (Virtual Observatory)
Isophotal analysis of M87, using data from the Advanced Camera for Surveys, reveals a projected displacement of 6.8+/-0.8pc (~0.1") between the nuclear point source (presumed to be the location of the supermassive black hole, SMBH) and the photo-center of the galaxy.
Description
The displacement is along a position angle of 307+/-17{deg} and is consistent with the jet axis. This suggests the active SMBH in M87 does not currently reside at the galaxy center of mass, but is displaced in the counter-jet direction.
Possible explanations for the displacement include orbital motion of an SMBH binary, gravitational perturbations due to massive objects (e.g., globular clusters), acceleration by an asymmetric or intrinsically one-sided jet, and gravitational recoil resulting from the coalescence of an SMBH binary.
