Redshift measurements of the brightest cluster galaxies of the gravitational lens 0957+561,rements have been used to separate field galaxies from members of the lensing cluster at . = 0.355, allowing the determination of a luminosity-weighted 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

The Triple Quasar PG1115+080,he time-delay is stable against small perturbations in the image positions. The Triple Quasar PG1115+080 is among the very few such candidates. The photometry of its individual images and redshift measurement of the lensing galaxy should turn out to be useful towards a reliable estimate of the Hubbl

1830-211 as a lens artefact,vitational lens hypothesis. It is suggested that the increase with frequency of the NE/SW flux ratio in the compact components can be accounted for chiefly by the core-knot structure of the source. Simulations of the ring structure at 1.69 GHz and the map at 15 GHz are presented. Speculations about

Inverse Systems – Nanoporous Solidsnal lens systems. Preliminary analysis indicates that we have not found any new systems with sub-arcsecond separations and components having a magnitude 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 t
