CMB-S4: Forecasting Constraints on $f_{\mathrm{NL}}$ Through $\mu$-distortion Anisotropy

David Zegeye, Federico Bianchini, J. Richard Bond +14

Diffusion damping of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. At redshift $5 \times 10^4…
