On the orientation of double galaxies,of alignment as the other galaxies belonging to the supercluster. The galaxy planes tend to be perpendicular to the plane of the parent supercluster and perpendicular to the radius-vectors from the centre of the supercluster. The angle between the rotation axes of galaxies in pairs, denoted as ., wa

A search for homogeneous samples of quasars,on is the UV excess of low and medium redshift quasars. The second criterion is the presence of emission lines. 25 000 non-overlapping spectra in the ESO/SRC field No. 411 were analyzed; 600 show UV excess, 2 500 spectra have apparent emission lines. Both criteria taken separately lead to a large nu

Slit spectroscopy of candidates from automated quasar detection on UKSTU prism plates, be extensively covered by the ROSAT all-sky soft X-ray survey. The present search aims at providing a data base of optically selected extragalactic objects which may later be compared with the sample of X-ray selected objects. The quasar candidates were identified on objective prism plates from the

The use of quasars for the construction of a future extragalactic inertial reference frame,e candidate objects depends on their individual optical and/or radio properties. Optical and Radio quasar survey projects will provide a sound basis to achieve this goal..Most aspects of this astrometric key-project have been discussed extensively in the recent literature. Instead of duplicating thi
