Abstract.
A Killing submersion is a Riemannian submersion from an orientable $3$-manifold to an orientable surface, such that the fibers of the submersion are the integral curves of a non-vanishing Killing vector field. The interest of this family of structures is that it yields a common treatment for a vast family of $3$-manifolds, including, among others, the simply-connected homogeneous ones and the warped products with $1$-dimensional fibers.
