  We study the charge-dependent azimuthal correlations in relativistic heavy
ion collisions, as motivated by the search for the Chiral Magnetic Effect (CME)
and the investigation of related background contributions. In particular we aim
to understand how these correlations induced by various proposed effects evolve
from collisions with AuAu system to that with UU system. To do that, we
quantify the generation of magnetic field in UU collisions at RHIC energy and
its azimuthal correlation to the matter geometry using event-by-event
simulations. Taking the experimental data for charge-dependent azimuthal
correlations from AuAu collisions and extrapolating to UU with reasonable
assumptions, we examine the resulting correlations to be expected in UU
collisions and compare them with recent STAR measurements. Based on such
analysis we discuss the viability for explaining the data with a combination of
the CME-like and flow-induced contributions.
