That is what I meant by "host galaxies" as well. In Arp's model, the ejected matter from active galaxies is first in form of cloud of particles which then condenses to form a quasar. It is unlikely that all the ejected particles end up into the quasar, so you get a quasar that is surrounded by a cloud of particles. Later that quasar surrounded with particles will evolve into a galaxy having the quasar as nucleus and the surrounding cloud as the disk of matter.
Quasars with host galaxies are expected in Arp's model.
