Thermal Particle and Photon Production in Pb+Pb Collisions with Transverse Flow
J. Cleymans, K. Redlich, D. Srivastava
Particle and photon production is analyzed in the presence of transverse flow using two approximations to describe the properties of the hadronic medium, one containing only $π, ρ,…
Large-Scale Structures Behind the Southern Milky Way from Observations of Partially Obscured Galaxies
R. C. Kraan-Korteweg, P. A. Woudt, P. A. Henning
We report here on extragalactic large-scale structures uncovered by a deep optical survey for galaxies behind the southern Milky Way. Systematic visual inspection of the ESO/SRC-su…
Local freedom in the gravitational field
Roy Maartens, George Ellis, Stephen Siklos
In a cosmological context, the electric and magnetic parts of the Weyl tensor, E_{ab} and H_{ab}, represent the locally free curvature - i.e. they are not pointwise determined by t…
Integrability of irrotational silent cosmological models
H van Elst, C Uggla, W Lesame +2
We revisit the issue of integrability conditions for the irrotational silent cosmological models. We formulate the problem both in 1+3 covariant and 1+3 orthonormal frame notation,…
Gravity and Signature Change
Tevian Dray, George Ellis, Charles Hellaby +1
The use of proper ``time'' to describe classical ``spacetimes'' which contain both Euclidean and Lorentzian regions permits the introduction of smooth (generalized) orthonormal fra…
Comment on `Smooth and Discontinuous Signature Type Change in General Relativity'
Tevian Dray, Charles Hellaby
Kossowski and Kriele derived boundary conditions on the metric at a surface of signature change. We point out that their derivation is based not only on certain smoothness assumpti…
