The effect of the Zone of Avoidance on the measurement of the acceleration of the Local Group

Magdalena Krupa, Maciej Bilicki and Agnieszka Pollo

One of the main assumptions of the standard family of cosmological models is the homogeneity of the Universe. But are the galaxies really uniformly distributed in the sky? Observations of the clustering dipole in the galaxy distribution can inform us about the movement of our Galaxy with respect to the rest–frame density field of galaxies and dark matter, and this measurement is independent of the estimations based on the Cosmic Microwave Background (CMB) dipole. However, all–sky galaxy surveys are needed for measuring this dipole. Is it possible to overcome the problems caused by the Zone of Avoidance?
