Astrophysical evidence for the existence of black holes
Annalisa Celotti, John C. Miller, Dennis W. Sciama
Following a short account of the history of the idea of black holes, we present a review of the current status of the search for observational evidence of their existence aimed at…
On the Interaction Between Cosmic Rays and Dark Matter Molecular Clouds - II. The Age Distribution of Cosmic Ray Electrons
D. W. Sciama
We explore further the proposal in paper I of this series that the confinement time of cosmic ray nuclei in the Milky Way is determined by their interaction with dark matter molecu…
On the Interaction Between Cosmic Rays and Dark Matter Molecular Clouds in the Milky Way. l Basic Considerations
D. W. Sciama
We explore some basic observational consequences of assuming that the dark matter in the Milky Way consists mainly of molecular clouds, and that cosmic rays can penetrate these clo…
Sonoluminescence as a QED vacuum effect. II: Finite Volume Effects
Stefano Liberati, Matt Visser, Francesco Belgiorno +1
In a companion paper [quant-ph/9904013] we have investigated several variations of Schwinger's proposed mechanism for sonoluminescence. We demonstrated that any realistic version o…
Sonoluminescence as a QED vacuum effect. I: The Physical Scenario
Stefano Liberati, Matt Visser, Francesco Belgiorno +1
Several years ago Schwinger proposed a physical mechanism for sonoluminescence in terms of changes in the properties of the quantum-electrodynamic (QED) vacuum state. This mechanis…
Sonoluminescence: Two-photon correlations as a test of thermality
Francesco Belgiorno, Stefano Liberati, Matt Visser +1
In this Letter we propose a fundamental test for probing the thermal nature of the spectrum emitted by sonoluminescence. We show that two-photon correlations can in principle discr…
