Abstract
The theoretical presumptions and some experimental calculations to analyse the speeds of the galaxies
movements according to redshift measurements applying the Doppler effect are presented. The speed of the galaxy
movement is treated as multidimensional continuous value, when values of the speed vector are calculated according
to measurements of the redshift parameter z at corresponding moments of the universe lookback time. The most reliable
values of the galaxy speeds vector are calculated applying the least square method to the vector of z measurements
and including the additional parameters to eliminate the possible systematic errors. The acceleration of the galaxy
movement is calculated as a speed fluxion according to period of the adopted redshift signal frequency and as a speed
change during the lookback time interval. The expressions of functions of the galaxies speeds and accelerations are
received by the polynomial approximation, when values of the polynomial parameters are calculated by the least
square method.
