Development of a carbon fibre composite active mirror: Design and testing
S. Kendrew, P. Doel, D. Brooks +5
Carbon fibre composite technology for lightweight mirrors is gaining increasing interest in the space- and ground-based astronomical communities for its low weight, ease of manufac…
Quantifying the Cosmic Web in the New Era of Redshift Surveys
Ofer Lahav
Two main strategies have been implemented in mapping the local universe: whole-sky 'shallow' surveys and 'deep' surveys over limited parts of the sky. The two approaches complement…
The very rich massive post-main-sequence star population of the open cluster Westerlund 1
Ignacio Negueruela, J. Simon Clark
We report the discovery of a population of Wolf-Rayet stars in the young Galactic open cluster Westerlund 1. In an incomplete shallow spectroscopic survey, we find six nitrogen-ric…
Stellar Parameters of Wolf-Rayet Stars from Far-UV to Mid-IR Observations
Paul A Crowther
Recent results for Galactic and Magellanic Cloud Wolf-Rayet stars are summarised based on line blanketed, clumped model atmospheres together with UV, optical and IR spectroscopy. T…
