Cross-correlation between thermal Sunyaev-Zeldovich effect and the
  integrated Sachs-Wolfe effect
  Large-angle fluctuations in the cosmic microwave background temperature
induced by the integrated Sachs-Wolfe effect and Compton-y distortions from the
thermal Sunyaev-Zeldovich (tSZ) effect are both due to line-of-sight density
perturbations. Here we calculate the cross-correlation between these two
signals. Measurement of this cross-correlation can be used to test the redshift
distribution of the tSZ distortion, which has implications for the redshift at
which astrophysical processes in clusters begin to operate. We also evaluate
the detectability of a yT cross-correlation from exotic early-Universe sources
in the presence of this late-time effect.
