CMB seen through random Swiss Cheese

Understand

We consider a Swiss Cheese model with a random arrangement of Lema\^itre--Tolman--Bondi holes in $\Lambda$CDM cheese.

• We study two kinds of holes with radius $r_b=50 h^{-1}$Mpc, with either an underdense or an overdense centre, called the open and closed case, respectively.
• We calculate the effect of the holes on the temperature, angular diameter distance and, for the first time in Swiss Cheese models, shear of the CMB.
• We quantify the systematic shift of the mean and the statistical scatter, and calculate the power spectra.
