  We present direct photon-hadron correlations in 200 GeV/A Au$+$Au, $d$$+$Au
and $p$$+$$p$ collisions, for direct photon $p_T$ from 5--12 GeV/$c$, collected
by the PHENIX Collaboration in the years from 2006 to 2011. We observe no
significant modification of jet fragmentation in $d$$+$Au collisions,
indicating that cold nuclear matter effects are small or absent. Hadrons
carrying a large fraction of the quark's momentum are suppressed in Au$+$Au
compared to $p$$+$$p$ and $d$$+$Au. As the momentum fraction decreases, the
yield of hadrons in Au$+$Au increases to an excess over the yield in $p$$+$$p$
collisions. The excess is at large angles and at low hadron $p_T$ and is most
pronounced for hadrons associated with lower momentum direct photons.
Comparison to theoretical calculations suggests that the hadron excess arises
from medium response to energy deposited by jets.
