Kinetic Sunyaev Zel'dovich velocity reconstruction from Planck and unWISE (2405.00809v1)

Published 1 May 2024 in astro-ph.CO, astro-ph.GA, and gr-qc

Abstract: The kinetic Sunyaev Zel'dovich (kSZ) effect is a blackbody cosmic microwave background (CMB) temperature anisotropy induced by Thomson scattering off free electrons in bulk motion with respect to the CMB rest frame. The statistically anisotropic cross-correlation between the CMB and galaxy surveys encodes the radial bulk velocity (more generally, the remote dipole field), which can be efficiently reconstructed using a quadratic estimator. Here, we develop and implement a quadratic estimator for the remote dipole field to data from the Planck satellite and the unWISE galaxy redshift catalog. With this data combination, we forecast a $\sim 1$-$\sigma$ detection within $\Lambda$CDM assuming a simple model for the distribution of free electrons. Using reconstructions based on individual frequency temperature maps, we characterize the impact of foregrounds, concluding that they can be effectively mitigated by masking and removing the estimator monopole. We demonstrate that reconstructions based on component-separated CMB maps have no detectable biases from foregrounds or systematics at the level of the expected statistical error. We use these reconstructions to constrain the multiplicative optical depth bias to $b_v < 1.40$ at $68 \%$ confidence. Our fiducial signal model with $b_v =1$ is consistent with this measurement. Our results support an optimistic future for kSZ velocity reconstruction with near-term datasets.
