Pawl et al. create mock Astro-E2 observations from their simulated clusters.

Seager et al. consider the spectroscopic biosignature of extrasolar planets.

Gies & Hesel claim that ice ages correspond to the Sun traversing spiral arms.

Sanders et al. present deep Chandra imaging of the Perseus cluster. They find a high-abundance shell which they suggest is the edge of a fossil bubble. They also detect non-thermal emission with a total luminosity of 4.8x10^43 erg/s and use this to map the magnetic field in the core of the cluster.

Weisskopf et al. provide a detailed description of the Chandra hardware and in-orbit performance.

de Diego et al. argue that the Pioneer anomalous acceleration is due to the Kuiper belt.
