  We report charged-particle pair correlation analyses in the space of Delta
-phi (azimuth) and Delta -eta (pseudo-rapidity), for central Au + Au collisions
at sqrt{s_{NN}} = 200 GeV in the STAR detector. The analysis involves
unlike-sign charge pairs and like-sign charge pairs, which are transformed into
charge-dependent (CD) signals and charge-independent (CI) signals. We present
detailed parameterizations of the data. A model featuring dense gluonic hot
spots as first proposed by van Hove predicts that the observables under
investigation would have sensitivity to such a substructure should it occur,
and the model also motivates selection of transverse momenta in the range 0.8 <
p_t < 2.0$ GeV/c. Both CD and CI correlations of high statistical significance
are observed and possible interpretations are discussed.
