Two particle number and momentum correlations for $\sqrt{s_{NN}} = $200 GeV Au$+$Au collisions at STAR

Recent two-particle correlation measurements of Au$+$Au collisions at $\sqrt{s_{NN}} = $200 GeV at STAR differ from previous p$+$p correlation results due to the appearance of strong long-range correlations in relative pseudorapidity, a phenomenon known as ``the ridge.'' Using three different number and transverse momentum pair correlation observables, we investigate the ridge and related phenomena as a function of collision centrality and charge dependence. Parameters for a Gaussian fit in $\Delta\eta$ and harmonic coefficients in $\Delta\phi$ are extracted for number correlations.
