... Abstract . ... A Survey for Supernovae in Massive High-Redshift Clusters . ... Combined optical and x-ray image of the "Bullet" galaxy cluster: the red outlines the distribution of hot, baryonic gas (from X-rays); the blue maps the underlying (dark matter) mass distribution. ... Galaxy-galaxy lenses, however, offer a distinct advantage, since the background source is extended, and therefore imposes a stronger constraints on the mass distribution of the lensing galaxy than a point-source QSO. ...
