Redshift measurements of the brightest cluster galaxies of the gravitational lens 0957+561,d centre for the cluster and a tentative value for its radial velocity dispersion ≈ 550 km s?1. These data also provide evidence that there may be an additional group or cluster of galaxies at . = 0.503.

Optical observations of gravitational lenses,cases (essentially multiply imaged quasars and micro-lensed candidates. Preliminary results of lensing statistics applied to a sample of more than 200 highly luminous quasars are then presented both for the effectiveness parameter . of galaxies and for the density parameter .. of compact lenses to produce macro-lensed images of distant quasars.

Steckt der Teufel im Teilchen?,ly recent analysis of early X-ray observations yields a core-halo model consistent with models for the lens. The ultimate uncertainty achievable for point estimates of the Hubble constant Ho remains larger than initially hoped for.

Inverse Systems – Nanoporous Solidsde difference of ≤ 1.5 mag. Galaxy count statistics around 94 quasars with photometric data are analysed. Within radii of 6″, 10″, and 15″, and down to a Gunn . magnitude of 23, we find no significant enhancement of galaxy density over the background counts.
