The Galaxy Environment of QSOs in Large Quasar Groups C.P. Haines et al. ... We are investigating the galaxy environment of the Clowes & Campusano (MNRAS 249, 218 [1991]) LQG of 18 QSOs at z ' 1:3, by combining ultra-deep optical images (to V ' 27; I ' 26) of a 30 0  30 0 eld containing 3 of the LQG quasaars with NIR imag- ing (K ' 20) of selected sub elds to obtain photometric redshift estimates for each galaxy from their V IK colours. ...

Authors: V.A. Marsakov , T.V. Borkova , . ... It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy. The thick disk and proto-disk subsystems are genetically associated with the Galaxy. ... It is argued that heavy-element enrichment and the collapse of the proto-galactic medium occurred mainly in the period between the formation of the proto-disk halo and thick disk subsystems. ...
