Low- and intermediate-$p_T$ azimuthal di-hadron correlations from $\sqrt{s_{NN}}=200 \rm{GeV}$ central AuAu collisions measured in STAR

Low- and intermediate-$p_T$ di-hadron correlations have already uncovered novel and exciting results at RHIC, tying together hard processes with bulk properties. We present systematic studies of di-hadron correlations for various trigger and associated $p_T$ selections, starting in the coalesence dominated region and extending up into the domain of fragmentation dominated triggers. We study the effects of varying the $\Delta\eta$- and $\Delta\phi$-integration windows within the STAR acceptance. The results are discussed in light of the interplay between radiative, hydrodynamic and recombination scenarios.
