Roelofs et al. derive parallaxes for a set of AM CVn binaries and predict LISA GW signals.

Dietrich et al. describe BLOX, a program to select galaxy clusters based on optical, X-ray and weak lensing shear.

Percival et al. measure the baryon oscillation signal at z=0.2 and z=0.35 using SDSS and 2dFGRS to constrain w=-1.004 +/- 0.089 for a flat model including the supernova and CMB constraints.

Wallin et al. place limits on deviations from Newtonian gravity in the outer Solar System through observations of the orbits of TNOs.

Markevitch points out that X-ray emission from clusters of galaxies depends on the He abundance in their cores which is unknown (and may be enhanced due to sedimentation). Combining SZ measurements with distances determined using other techniques can be used to estimate the He abundance.

Ruiter et al. calculate the LISA foreground due to mass-transferring binaries and find that it becomes significant at frequencies above ~7 mHz.

Bickel et al. develop methods for searching for periodicity in photon event times with application in the gamma-ray regime.

Prix & Whelan apply F-statistic methods developed for LIGO to the MLDC binary challenges.
