Redshift effects implications on revised models of Stephan's quintet

Abstract: Recent observations of Stephan's Quintet gave new indications on its formation scenario. Older formation and a role of NCG 7317 should be considered in revised numerical models of the compact group. Velocities of group members to recreate are estimated from redshift measurements. Several effects contribute to observed redshifts and a new effect is predicted to be the result of the gravitational interaction between photons and constant magnetic fields creating gravitational waves. The energy carried by these waves is manifested as redshifts of photons. Cosmological simulations data are used to prove the significant contribution of our effect. The analysis of synthetic observations created from those simulations has shown that redshifts differences of Stephanes Quintet members could be misinterpreted as caused only from Doppler Effect. The revised models of the group should consider a new method to recreate the formation scenario based on redshift patterns and not mis-estimated velocities.
