OH in Messier 82
M. K. Argo, A. Pedlar, T. W. B. Muxlow +4
Several new main line OH masers have been detected in the nearby starburst galaxy M82. Eight masers have been detected to 5 sigma, six of which are new detections. Observations cov…
Bulk black holes radiating in non-Z_2 brane-world spacetimes
David Jennings, Ian R. Vernon, Anne-Christine Davis +1
In this paper we present a general asymmetric brane model involving arbitrary energy transport to and from an embedded 4-D FRW universe. We derive a locally defined mass function f…
On the arithmetic of tight closure
Holger Brenner, Mordechai Katzman
We provide a negative answer to an old question in tight closure theory by showing that the containment x^3y^3 \in (x^4,y^4,z^4)^* in K[x,y,z]/(x^7+y^7-z^7) holds for infinitely ma…
Probing quantum decoherence in atmospheric neutrino oscillations with a neutrino telescope
Dean Morgan, Elizabeth Winstanley, Jurgen Brunner +1
Quantum decoherence, the evolution of pure states into mixed states, may be a feature of quantum gravity. In this paper, we show how these effects can be modelled for atmospheric n…
Cosmic Acceleration in Massive Half-Maximal Supergravity
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis
We consider massive half-maximal supergravity in (d+3) dimensions and compactify it on a symmetric three space. We find that the static configurations of Minkowski X S^3, obtained…
Numerical Modelling of the Microcavity OPO
D. M. Whittaker
A detailed description is provided of a numerical model of the microcavity optical parametric oscillator (OPO). The model is solved on a two dimensional grid, in the time domain, u…
