Gamma-Ray Summary Report
J. Buckley, T. Burnett, G. Sinnis +7
This paper reviews the field of gamma-ray astronomy and describes future experiments and prospects for advances in fundamental physics and high-energy astrophysics through gamma-ra…
Quark-Gluon Plasma in the Early Universe
Joseph I Kapusta
A QCD phase transition in the early universe could have left inhomogeneities in the baryon to photon ratio and in isospin that might have affected nucleosynthesis later on. At very…
Primordial Black Holes and Hot Matter
Joseph I Kapusta
Microscopic black holes explode with their temperature varying inversely as their mass. Such explosions would lead to the highest temperatures in the present universe, all the way…
False Vacuum Black Holes and Universes
R. G. Daghigh, J. I. Kapusta, Y. Hosotani
We construct a black hole whose interior is the false vacuum and whose exterior is the true vacuum of a classical field theory. From the outside the metric is the usual Schwarzschi…
The Last Eight Minutes of a Primordial Black Hole
Joseph Kapusta
About eight minutes before a black hole expires it has a decreasing mass of 10^{10} g, an increasing temperature of 1 TeV, and an increasing luminosity of 7x10^{27} erg/s. I show t…
Probing the Space-Time evolution of Heavy Ion Collisions with Bremsstrahlung
J. I. Kapusta, S. M. H. Wong
We examine the bremsstrahlung photons emitted in the central collisions of two gold nuclei at the Relativistic Heavy Ion Collider. While the measurements of the final hadrons can r…
