The kSZ optical depth degeneracy and future constraints on local primordial non-Gaussianity
Avery J. Tishue, Charuhas Shiveshwarkar, Gilbert Holder
Recent reconstructions of the large-scale cosmological velocity field with kinetic Sunyaev Zeldovich (kSZ) tomography have returned an amplitude that is low with respect to the hal…

Neutrino Mass Constraints from kSZ Tomography
Avery J. Tishue, Selim C. Hotinli, Peter Adshead +2
We forecast neutrino mass constraints using Stage IV CMB and large-scale structure surveys, focusing on kSZ tomography as an independent probe of the growth of cosmic structure. We…

Probing beyond local-type non-Gaussianity with kSZ tomography
Peter Adshead, Avery J. Tishue
Non-Gaussianity of the primordial curvature perturbations may arise from a variety of well motivated early Universe scenarios. In particular, inflationary theories with additional…
