Query: Initial fluctuations and power spectrum of flow anisotropies in
  relativistic heavy-ion collisions   Flow has emerged as a crucial probe for the properties of the thermalized
medium produced in relativistic heavy-ion collisions. The evolution of initial
state fluctuations leaves imprints on the power spectrum of flow coefficients.
Therefore flow coefficients are a crucial probe of initial state fluctuations
arising from the parton distributions of the colliding nuclei. This has a very
strong correspondence with the physics of power spectrum of cosmic microwave
background radiation (CMBR) anisotropies which directly probes initial
inflationary fluctuations. Much work has been done to probe these interesting
interconnections, in particular, in developing techniques for the measurements
of higher flow coefficients. We present a short review of these developments.
The effect of initial magnetic field on these features will also be reviewed.
All this acquires special importance in view of upcoming electron-ion collider
which will directly probe initial parton distribution of the colliding nucleus.
