Raagini Patki, A Novel Bispectrum extracting the Kinematic SZ effect as a Cosmological Probe (2:00 PM - 2:30 PM)

-- Abstract: Over the past decade, the kinematic Sunyaev-Zel'dovich (kSZ) effect has emerged as a unique observational probe of the distribution of baryons and velocity fields in the Universe. In this 30-minute talk, I will briefly review the kSZ effect and present our recent work (arXiv:2411.11974), proposing a novel 'bispectrum' of the form temperature-temperature-density to extract it from cleaned CMB maps. This estimator can utilize any tracer of the large-scale structure density field projected along the line-of-sight and does not require individual redshifts. With this new method, we forecast high signal-to-noise ratios (SNR) of ∼100 for the upcoming Simons Observatory (SO) and CMB-S4 correlated with a galaxy sample from WISE that is restricted to the linear regime. We show the SNR peaks for squeezed triangles with a short (linear) density mode and long temperature modes in harmonic space. We study the cosmological dependence of this kSZ signal and forecast initial constraints on the sum of neutrino masses for SO and CMB-S4. Finally, I will discuss the advantages of this estimator and its prospects as a novel probe of baryonic abundance and beyond-ΛCDM cosmology with upcoming precision measurements.
