CLASS B 1359+154：Modelling Lensing by a Group of Galaxies
Gravitational lensing multiple-imagin individual systems
2009/5/19
The recently discovered gravitationally lensed system CLASS
B1359C154 appears to have six detectable images of a single background
source at a redshift of 3:235. A group of galaxies acts as the lens...

2009/2/13
In this paper the problem of the phenomenological modelling of
elliptical galaxies using various available observational data is presented. Recently,
Tortora, Cardona and Piedipalumbo (2007) suggest...
