During
the 2010 and 2011 RHIC runs, significant running time was devoted
to examine Au+Au collisions over a broad range of energies from
7.7 to 200 GeV per nucleon-nucleon pair.This energy scan was
designed to search for turn-off of the new phenomena that
characterize the quark-gluon plasma at RHIC, and to look for
evidence for the QCD critical point and first-order phase
transition that are expected at finite baryon chemical potential.Identified particle
spectra, flow, correlations, and fluctuations have all been
measured.In
parallel, measurements of heavy flavor production and flow
fluctuations in 200 GeV Au+Au collisions have provided new
insights into the properties of the QGP, while studies of
correlations in d+Au collisions at forward rapidities have
provided evidence for gluon saturation. An overview of these
recent results will be presented.
