Measuring -Distortions from the Thermal Sunyaev-Zeldovich effect
David Zegeye, Thomas Crawford, Wayne Hu
The thermal Sunyaev-Zel'dovich (tSZ) effect is a spectral distortion of the cosmic microwave background (CMB) resulting from inverse Compton scattering of CMB photons with electron…

CMB-S4: Forecasting Constraints on Through -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…
