  Two-particle correlations and event-wise fluctuations in transverse momentum
p_t are reported for Au-Au collisions at sqrt{s_{NN}} = 62 and 200 GeV on
pseudorapidity (eta) and azimuth (phi). Distributions of all pairs of particles
(no leading trigger particle) reveal jet-like correlations, or peaks at
pair-wise opening angles of order 1 radian or less. The width of this same-side
correlation peak increases dramatically on pseudorapidity and decreases on
azimuth for increasing collision centrality. Evolution of the same-side peak
with centrality suggests dissipation of low-Q^2 partons via strong coupling to
an expanding bulk medium. p_t correlations, which provide access to temperature
and/or velocity distributions in the colliding system, are also presented.
