Jet propagation is shown to produce Mach-cone-like medium excitation inside a quark-gluon plasma. However, only deflection of such medium excitation and jet shower partons by radial flow leads to double-peaked dihadron correlation in high-energy heavy-ion collisions. Dihadron correlations from harmonic flow, hot spots and dijets are studied separately within the AMPT Monte Carlo model and all lead to double-peaked dihadron azimuthal correlation. The γ-hadron correlation has similar double-peak feature but is free of the contributions from harmonic flow and hot spots. Dihadron and γ-hadron correlations are compared to shed light on jet-induced medium excitation and hot spots in an expanding medium.
