... For this paper: postscript PPEUC CMB index 1 Introduction.. ... We present a new model for the formation of spherically symmetric clusters in an expanding Universe. Both the Universe and the collapsing cluster are governed by the same pressure less fluid equations for which a uniform initial density profile is assumed. ... The computation of photon paths allows us to evaluate the gravitational effects imprinted on a Cosmic Microwave Background (CMB) photon passing through such an evolving mass. ...

... The design employs a differential structure. ... The input is adapted to 100 differential, and the outputs use standard Low Voltage Differential Signaling (LVDS). ...
