The single ionization of noble gas atoms by an attosecond pulse train assisted by an infrared laser field is theoretically investigated by means of a non-perturbative model that under certain approximations gives closed-form expressions for the angular distributions of photoelectrons. A very good agreement between our predictions and experiments is observed. Interestingly, our model allow us to interpret these angular distributions as two-center interferences where the separation between centers is governed by the infrared laser field. Finally, we provide a physical interpretation for the analogy of the two-center interferences.
