Are Exomoons Habitable?

Some exoplanets seem to have walked directly out of the best science fiction movies. Taking these planets into example, the question of habitability seems like a joke. But what if we stopped looking at these extreme worlds and turned our eyes to their moons instead? Surely their moons are less extreme. And given that our own Jupiter hosts 67 moons, surely they’re more abundant. Can such extreme planets host habitable moons? The 36-page paper written by Heller and Barnes attempts to address this question.
