trailAnalogue Hawking radiation has been observed in laboratory systems.
Black holes emit Hawking radiation.
The derivation of Hawking radiation depends on unknown trans-Planckian physics.
The predicted Hawking spectrum is insensitive to modifications of trans-Planckian dispersion relations.

Spontaneous emission in Bose-Einstein condensates· for
Spontaneous analogue Hawking radiation has been detected at sonic horizons in Bose-Einstein condensates.
Steinhauer's Technion experiments observed correlated phonon pairs across a sonic horizon in a Bose-Einstein condensate.
The correlation spectrum measured at a BEC sonic horizon was thermal at the temperature predicted by Hawking's formula.
Analogue gravity predicts that sonic horizons in flowing fluids emit thermal Hawking-like phonon radiation.
Stimulated emission in fluids and optics· for
Stimulated Hawking emission has been measured at analogue horizons in water-wave experiments.
atomic
Stimulated analogue Hawking radiation has been observed in nonlinear optical systems.
atomic
Classical-noise reinterpretation of the BEC signal· against
The reported BEC analogue Hawking signal can be explained by amplified classical noise rather than quantum vacuum emission.
shared · shown elsewhere
assumed
The Hawking effect is a kinematic phenomenon arising in any system with an effective horizon.
