The XMM-Newton serendipitous survey. IV. Optical identification of the XMM-Newton medium sensitivity survey (XMS) (2007)
Journal Article

Aims.X-ray sources at intermediate fluxes (a few 10-14 erg cm-2 s-1) with a sky density of ~100 deg-2 are responsible for a significant fraction of the cosmic X-ray background at various energies below 10 keV. The aim of this paper is to provide an u... Read More about The XMM-Newton serendipitous survey. IV. Optical identification of the XMM-Newton medium sensitivity survey (XMS).

Herwig++ 2.1 Release Note (2007)
Journal Article

A new release of the Monte Carlo program Herwig++ (version 2.1) is now available. This version includes a number of significant improvements including: an eikonal multiple parton-parton scattering model of the underlying event; the inclusion of Beyon... Read More about Herwig++ 2.1 Release Note.

Spiroconjugation-enhanced intramolecular charge-transfer state formation in a polyspirobifluorene homopolymer (2007)
Journal Article

In this work we demonstrate the complex excited-state behavior of polyspirobifluorene in the solid state, which, due to the interaction of the spiroconjugated side group, readily forms a charge-transfer (CT) excited state of lower energy than the sin...

A deep AAOmega survey of low-luminosity galaxies in the Shapley supercluster: stellar population trends (2007)
Journal Article

We present new optical spectroscopy for 342 R < 18 galaxies in the Shapley supercluster (and 198 supplementary galaxies), obtained from 8-h integrations with the AAOmega facility at the Anglo-Australian Telescope. We describe the observations and mea... Read More about A deep AAOmega survey of low-luminosity galaxies in the Shapley supercluster: stellar population trends.

The Orbital Period of the Wolf-Rayet Binary IC 10 X-1: Dynamic Evidence that the Compact Object Is a Black Hole (2007)
Journal Article

IC 10 X-1 is a bright (LX = 1038 ergs s-1) variable X-ray source in the Local Group starburst galaxy IC 10. The most plausible optical counterpart is a luminous Wolf-Rayet star, making IC 10 X-1 a rare example of a Wolf-Rayet X-ray binary. In this Le...
