Abstract
Gravitationally lensed QSOs GLQs at 1≤z≤2 play a key role in understanding the cosmic evolution of the innermost parts of active galaxies black holes accretion disks coronas and internal jets as well as the structure of galaxies at intermediate redshifts With respect to studies of normal QSOs GLQ programmes have several advantages For example a monitoring of GLQs may lead to unambiguous detections of intrinsic and extrinsic variations Both kinds of variations can be used to discuss central engines in distant QSOs and mass distributions and compositions of lensing galaxies In this context UV data are of particular interest since they correspond to emissions from the immediate surroundings of the supermassive black hole We describe some observation strategies to analyse optically bright GLQs at z∼15 using ISSIS CfS on board World Space ObservatoryUltraviolet
