Query: Studies of Heavy Flavor Jets Using $D^0$-hadron Correlations in Azimuth
  and Pseudorapidity in Au+Au Collisions at 200 GeV at the STAR Experiment   Heavy flavor (HF) quarks (charm, bottom) are important probes of the medium
produced in relativistic heavy-ion collisions because they are formed in the
early stage and propagate throughout the lifetime of the QGP medium. HF-meson
spectra and azimuthal anisotropy ($v_{2}$) measurements have been reported by
experiments at RHIC and the LHC, and they suggest strong interactions of HF
quarks with the medium. $D^{0}$-hadron correlations on relative pseudorapidity
and azimuth ($\Delta\eta,\Delta\phi$) provide a method for disentangling
correlation structures on ($\Delta\eta,\Delta\phi$), related to jets and bulk
phenomena directly, with the $D^{0}$ serving as a proxy for a charm jet. In
these proceedings, we present 2D $D^{0}$-hadron angular correlations as a
function of centrality in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. These
data reveal a jet-like, peaked structure at ($\Delta\eta,\Delta\phi$) = (0, 0)
(near-side), and a $\Delta\eta$-independent azimuthal harmonic modulation.
Here, we focus on the evolution of the near-side peak's yield and widths on
($\Delta\eta,\Delta\phi$) as a function of centrality and compare them to
results from light flavor correlations with a similar trigger mean-$p_{T}$.
