The LIGO detects gravitational waves - even from events that produce no

My thought is I wonder if its possible to create some kind of
gravitational wave detector that can view objects that don't produce a
lot of photons. Maybe there could be structures that wash out
photonically, by the background radiation, but spike big time, as grav
waves?
