# Quantum radiation from quantum gravitational collapse

@article{Vachaspati2008QuantumRF, title={Quantum radiation from quantum gravitational collapse}, author={Tanmay Vachaspati and Dejan Stojkovi{\'c}}, journal={Physics Letters B}, year={2008}, volume={663}, pages={107-110} }

We study quantum radiation emitted during the collapse of a quantized, gravitating, spherical domain wall. The amount of radiation emitted during collapse now depends on the wavefunction of the collapsing wall and the background spacetime. If the wavefunction is initially in the form of a sharp wavepacket, the expectation value of the particle occupation number is determined as a function of time and frequency. The results are in good agreement with our earlier semiclassical analysis and show… Expand

It seems that the Hawking effect is associated with themore rather than the event horizon, as an extrapolation of some properties of from a neighborhood of the Schwarzschild horizon to that of an apparent horizon forming in a collapse leads to the result that too much energy is radiated away already before the apparent horizon forms.
