Cosmic inflation is the theory thatthe universe underwent a violent,rapid expansion at the beginning oftime, giving rise to much of the ob-served structure in the universe [1].This theory is supported by indirectobservational evidence from manydifferent sources (e.g. see [2]). How-ever, direct experimental investiga-tion of inflation is of course impos-sible. For this reason there has beenconsiderableinterestinanalogmod-els for astrophysics (e.g. see [3]), inwhichanalogousbehaviorisstudiedin systems that are experimentallyconvenient.Due to their cleanness and greatflexibility, dilute ultra-cold atomicgases (particularly Bose-Einsteincondensates) form an attractivesystem for realizing such analogmodels. Indeed, a number of suchtable-top-astrophysics experimentshave been conducted with Bose-Einstein condensates. For example,supernova-like collapse and explo-sion dynamics [4], controlled bymodifying inter-atomic interactionsusing Feshbach resonances, andlater interpreted as cosmologicalparticle creation [5]; Faster-than-sound flow of a condensate hasbeen used to produce a sonic blackholeanalog[6];The
