Azimuthal angle ($\\Delta\\phi$) correlations are presented for a broad range of transverse momentum ($0.4 < p_{\\rm T} < 10$~GeV/$c$) and centrality (0-92%) selections for charged hadrons from di-jets in Au+Au collisions at $\\sqrt{s_{\\rm{NN}}}$ = 200 GeV. With increasing $p_{\\rm T}$, the away-side $\\Delta\\phi$ distribution evolves from a broad and relatively flat shape to a concave shape, then to a convex shape. Comparisons to $p+p$ data suggest that the away-side distribution can be divided into a partially suppressed \"head\" region centered at $\\Delta\\phi\\sim\\pi$, and an enhanced \"shoulder\" region centered at $\\Delta\\phi\\sim \\pi\\pm 1.1$. The $p_{\\rm T}$ spectrum for the associated hadrons in the head region softens toward central collisions. The spectral slope for the shoulder region is independent of centrality and trigger $p_{\\rm T}$. The properties of the near-side distributions are also modified relative to those in $p+p$ collisions, reflected by the broadening of the jet shape in $\\Delta\\phi$ and $\\Delta\\eta$, and an enhancement of the per-trigger yield. However, these modifications seem to be limited to $p_{\\rm T}\\lesssim4$ GeV/$c$, above which both the hadron pair shape and per-trigger yield become similar to $p+p$ collisions. These observations suggest that both the away- and near-side distributions contain a jet fragmentation component which dominates for $p_{\\rm T}\\gtrsim5$ GeV and a medium-induced component which is important for $p_{\\rm T}\\lesssim4$ GeV/$c$. We also quantify the role of jets at intermediate and low $p_{\\rm T}$ through the yield of jet-induced pairs in comparison to binary scaled $p+p$ pair yield. The yield of jet-induced pairs is suppressed at high pair proxy energy (sum of the $p_{\\rm T}$ magnitudes of the two hadrons) and is enhanced at low pair proxy energy. The former is consistent with jet quenching; the latter is consistent with the enhancement of soft hadron pairs due to transport of lost energy to lower $p_{\\rm T}$."}]},{"notation":[{"@value":"Per-trigger yield as function of partner $p_T$ for the HR region for the 0-20% Au + Au collisions.
