We consider a two-dimensional determinantal point process arising in the random normal matrix model and which is a two-parameter generalization of the complex Ginibre point process. In this paper, we prove that the probability that no points lie on any number of annuli centered at 0 satisfies large n asymptotics of the form where n is the number of points of the process. We determine the constants explicitly, as well as the oscillatory term which is of order 1. We also allow one annulus to be a disk, and one annulus to be unbounded. For the complex Ginibre point process, we improve on the best known results: (i) when the hole region is a disk, only were previously known, (ii) when the hole region is an unbounded annulus, only were previously known, and (iii) when the hole region is a regular annulus in the bulk, only was previously known. For general values of our parameters, even is new. A main discovery of this work is that is given in terms of the Jacobi theta function. As far as we know this is the first time this function appears in a large gap problem of a two-dimensional point process.
