In a relativistic heavy-ion collision, the connection between initial-state geometry and final anisotropic flow can be quantified through a well-established mapping between pT -integrated flow harmonics and cumulants of the initial transverse energy distribution. In this seminar, I show that this can be extended to also include pT -differential flow. In doing so, we find that subleading principal components of anisotropic flow can reveal previously unobserved details of the hydrodynamic response, in both the linear and the nonlinear regimes. Additionally, I show that they provide novel information on the small-scale structures present in the initial stage of relativistic heavy-ion collisions.
