Simulated curved-spacetime kinematics in laboratory systems with horizons and Hawking-like radiation, e.g. sonic horizons in Bose-Einstein condensates, water-tank analogues, and optical analogues. Claims about such experiments' setups, detections, and their bearing on Hawking radiation belong here; claims about astrophysical black holes themselves do not.
The reported BEC analogue Hawking signal can be explained by amplified classical noise rather than quantum vacuum emission.
