Tree amplitudes in gauge theory as scalar MHV diagrams (2004)
Journal Article
Georgiou, G., & Khoze, V. (2004). Tree amplitudes in gauge theory as scalar MHV diagrams. Journal of High Energy Physics, 2004(05), https://doi.org/10.1088/1126-6708/2004/05/070

It was proposed in hep-th/0403047 that all tree amplitudes in pure Yang-Mills theory can be constructed from known MHV amplitudes. We apply this approach for calculating tree amplitudes of gauge fields and fermions and find agreement with known resul... Read More about Tree amplitudes in gauge theory as scalar MHV diagrams.

Decoherence of Bose-Einstein condensates in microtraps. (2004)
Journal Article
Henkel, C., & Gardiner, S. (2004). Decoherence of Bose-Einstein condensates in microtraps. Physical Review A, 69(4), https://doi.org/10.1103/physreva.69.043602

We discuss the impact of thermally excited near fields on the coherent expansion of a condensate in a miniaturized electromagnetic trap. Monte Carlo simulations are compared with a kinetic two-component theory and indicate that atom interactions can... Read More about Decoherence of Bose-Einstein condensates in microtraps..

Controlled vortex-sound interactions in atomic Bose-Einstein condensate (2004)
Journal Article
Parker, N., Proukakis, N., Barenghi, C., & Adams, C. (2004). Controlled vortex-sound interactions in atomic Bose-Einstein condensate. Physical Review Letters, 92(16), https://doi.org/10.1103/physrevlett.92.160403

The low temperature dynamics of a vortex in a trapped quasi-two-dimensional Bose-Einstein condensate are studied quantitatively. Precession of an off-centered vortex in a dimple trap, embedded in a weaker harmonic trap, leads to the emission of sound...

An XMM-Newton view of M101 - I. The luminous X-ray source population. (2004)
Journal Article
Jenkins, L., Roberts, T., Warwick, R., Kilgard, R., & Ward, M. (2004). An XMM-Newton view of M101 - I. The luminous X-ray source population. Monthly Notices of the Royal Astronomical Society, 349(2), 404-424. https://doi.org/10.1111/j.1365-2966.2004.07546.x

We present the first results of an XMM–Newton EPIC observation of the luminous X-ray source population in the face-on supergiant spiral galaxy M101. We have studied the spectral and temporal properties of the 14 most luminous sources, all of which ha... Read More about An XMM-Newton view of M101 - I. The luminous X-ray source population..

The 2dF QSO Redshift Survey - XII. The spectroscopic catalogue and luminosity function (2004)

We present the final catalogue of the 2dF QSO Redshift Survey (2QZ), based on Anglo-Australian Telescope 2dF spectroscopic observations of 44 576 colour-selected (ubJr) objects with 18.25

Fast, large and controllable phase modulation using dual frequency liquid crystals (2004)
Journal Article
Kirby, A., & Love, G. (2004). Fast, large and controllable phase modulation using dual frequency liquid crystals. Optics Express, 12(7), 1470-1475. https://doi.org/10.1364/opex.12.001470

We report on a method for high speed, large stroke phase modulation using dual frequency control of liquid crystals. Our system uses an all-electronic feedback system in order to simplify the control. We show half wave phase modulations of ~120Hz wit...

Chandra observations of five ultraluminous X-ray sources in nearby galaxies (2004)
Journal Article
Roberts, T., Warwick, R., Ward, M., & Goad, M. (2004). Chandra observations of five ultraluminous X-ray sources in nearby galaxies. Monthly Notices of the Royal Astronomical Society, 349(4), 1193-1210. https://doi.org/10.1111/j.1365-2966.2004.07626.x

We report the results of a programme of dual-epoch Chandra ACIS-S observations of five ultraluminous X-ray sources (ULXs) in nearby spiral galaxies. All five ULXs are detected as unresolved, point-like X-ray sources by Chandra, though two have faded... Read More about Chandra observations of five ultraluminous X-ray sources in nearby galaxies.

A note on string interaction on the pp-wave background (2004)
Journal Article
Chu, C., Khoze, V., Petrini, M., Russo, R., & Tanzini, A. (2004). A note on string interaction on the pp-wave background. Classical and Quantum Gravity, 21(8), 1999-2009. https://doi.org/10.1088/0264-9381/21/8/006

We consider type IIB string interaction on the maximally supersymmetric pp-wave background and discuss how the bosonic symmetries of the background are realized. This analysis shows that there are some interesting differences with respect to the flat... Read More about A note on string interaction on the pp-wave background.

The inner structure of ACDM haloes - III. Universality and asymptotic slopes (2004)
Journal Article

We investigate the mass profile of cold dark matter (ΛCDM) haloes using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters. These haloes typically have a few million particles within the v... Read More about The inner structure of ACDM haloes - III. Universality and asymptotic slopes.
