 Until recently, little philosophical work has been done on these analogue black holes. Dardashti et al. (2017) argue that such analogue models of event horizons and Hawking radiation can provide powerful confirmatory support for the existence of Hawking radiation around actual black holes. Indeed, they argue that these particular kinds of analogue model and the concomitant support they purport to provide are novel, both in the sense of being of a sort not investigated before in the philosophical literature and in the sense of representing an innovation in actual scientific practice. (See the Encyclopaedia entry  Analogy and Analogical Reasoning.)  They base their claim on the fact that these are not only theoretical models, but that they can be—and are—implemented as actual experiments, and thus constitute not merely analogical reasoning, but experimentally controlled physical simulation. If one accepts a certain kind of universality argument (Unruh and Schützhold 2005), they claim, then it is this latter characteristic that lends the analogue models the possibility of strong confirmatory support of actual Hawking radiation; and to the contrary, without acceptance of that universality argument—if the models were based merely on standard analogical theoretical reasoning—no confirmatory support at all would be had.
