dc.description.abstract
Only a few of the dozen or so known stellar-mass black holes have been observed away from the plane of the Galaxy1. Those few could have been ejected from the plane as a result of a ‘kick’ received during a supernova explosion, or they could be remnants of the population of massive stars formed in the early stages of evolution of the Galaxy. Determining their orbital motion should help to distinguish between these options. Here we report the transverse motion (in the plane of the sky) for the black-hole X-ray nova XTE J1118+480 (refs 2, 3, 4, 5), from which we derive a large space velocity. This X-ray binary system has an eccentric orbit around the Galactic Centre, like most objects in the halo of the Galaxy, such as ancient stars and globular clusters. The properties of the system suggest that its age is comparable to or greater than the age of the Galactic disk. Only an extraordinary ‘kick’ from a supernova could have launched the black hole into an orbit like this from a birthplace in the disk of the Galaxy.
