  We use the identification of the edge mode of the filling fraction $\nu=1$
quantum Hall phase with a 1+1 dimensional chiral Dirac fermion to construct an
analogue model for a chiral fermion in a space-time geometry possessing an
event horizon. By solving the model in the lowest Landau level, we show that
the event horizon emits particles and holes with a thermal spectrum. Each
emitted quasiparticle is correlated with an opposite-energy partner on the
other side of the event horizon. Once we trace out these "unobservable"
partners, we are left with a thermal density matrix.
