Abstract: Hawking\’s prediction of thermal radiation by black holes has been shown by Unruh to be expected also in condensed matter systems. We show here that in a black hole-like configuration realized in a BEC this particle-creation does indeed take place and can be unambiguously identified via a characteristic pattern in the density–density correlations. This opens the concrete possibility of the experimental verification of this effect.
