Item Doppler interpretation for close pairs and compact groups of quasars(American Astronomical Society, 1989-03-01) Narasimha, D.; Narlikar, J. V.We consider a Doppler model to account for (a) abnormal concentration of quasars in a given part of the sky and (b) the presence of two quasars with very nearly equal redshifts lying close to each other. The ejection parameters are explicitly determined and are shown to be reasonable for the nine quasars in the 1146+111 field. This example illustrates both (a) and (b). It is suggested that these calculations be carried out for quasars usually believed to be gravitationally lensed, as well as to other fields containing anomalously high concentration of quasars.
