Probing non-Gaussianity beyond the local-type with kSZ tomography

Primordial non-Gaussianity remains a key target for studying the physics of the early Universe. In this talk, I will discuss how kinematic Sunyaev-Zeldovich (kSZ) tomography has promise as a powerful probe of primordial non-Gaussianity beyond the standard local type. In particular, primordial non-Gaussianity can manifest as a source of scale-dependent galaxy bias. By using kSZ tomography as an additional probe of the large scale matter power spectrum, a better measurement of the scale-dependent galaxy bias is possible, enabling improved inference of the parameters that control the amplitude and shape (squeezed, equilateral, etc.) of the bispectrum of primordial curvature perturbations. I will also discuss discuss the robustness of these results to various biases, degeneracies, and survey details.
