Flow anisotropies, CMBR anisotropies and their interconnections

We will present the correspondences between the physics of Cosmic
Microwave Background anisotropies and the flow anisotropies developed
from initial state fluctuations in relativistic heavy ion collisions.
We will argue that some of the interesting features present in the
CMBR power spectrum may be present in the corresponding power spectrum
in relativistic heavy ion collisions. We will also discuss how the
techniques developed in CMBR data analysis could be used in analyzing
flow anisotropies in heavy ion collisions. The effect of magnetic
field on elliptic flow in non-central collisions will also be
discussed. Finally, we will present a new technique to analyze the
anisotropic expansion history in case of early universe as well as
heavy ion collisions by analyzing the geometry of the fluctuations.
