  Supermassive black holes ejected from galaxy nuclei by gravitational wave
recoil will carry a retinue of bound stars, even in the absence of an accretion
disk. We discuss the observable signatures related to these stars, with an
emphasis on electromagnetic flares from stars that are tidally disrupted by the
black hole. We calculate disruption rates for the bound, and the unbound,
stars. The rates are smaller than, but comparable to, rates for non-recoiling
black holes. A key observational consequence is the existence of powerful
off-nuclear and intergalactic X-ray flares. We also discuss other observable
signatures associated with the bound stars, including episodic X-ray emission
from accretion due to stellar mass loss; intergalactic supernovae; and feedback
trails.
