There is no solid measurement for the gravitational redshift on neutron stars either: not a lot of emission-lines to be found on that surface! So I'm not sure how this is relevant to either the OP, or to Arp's ideas.

parejkoj. Doppler broadening of iron emission lines has been seen,here:

That anything can be ejected from a galaxy, AGN, pulsar, etc...still seems lost to lots of folks out there. pete
