Abstract In (J. Stat. Phys. 132 , 275–290, 2008), Borodin and Péché introduced a generalization of the extended Airy kernel based on two infinite sets of parameters. For an arbitrary choice of parameters, we construct determinantal point processes on for these generalized kernels. In addition, for a subset of the parameter space, we show that the point processes can be lifted to line ensembles on , which satisfy the Brownian Gibbs property. Our ensembles generalize the wanderer line ensembles introduced by Corwin and Hammond (Invent. Math. 195 , 441–508, 2014).
