Two dimensional low-$p_T$ dihadron correlations in azimuthal angle $\phi$ andpseudo-rapidity $\eta$ in high-energy heavy-ion collisions are investigatedwithin both the HIJING Monte Carlo model and an event-by-event (3+1)D idealhydrodynamic model. Without final-state interaction and collective expansion,dihadron correlations from HIJING simulations have a typical structure fromminijets that contains a near-side two-dimensional peak and an away-side ridgealong the $\eta$-direction. In contrast, event-by-event (3+1)D idealhydrodynamic simulations with fluctuating initial conditions from theHIJING+AMPT model produce a strong dihadron correlation that has an away-sideas well as a near-side ridge. Relics of intrinsic dihadron correlation fromminijets in the initial conditions still remain as superimposed on the tworidges. By varying initial conditions from HIJING+AMPT, we study effects ofminijets, non-vanishing initial flow and longitudinal fluctuation on the finalstate dihadron correlations. With a large rapidity gap, one can excludenear-side correlations from minijet relics and dihadron correlations can bedescribed by the superposition of harmonic flows up to the 6th order. Whenlong-range correlations with a large rapidity gap are subtracted fromshort-range correlations with a small rapidity gap, the remaining near-sidedihadron correlations result solely from relics of minijets. Low transversemomentum hadron yields per trigger ($p_T^{\rm trig} <4$ GeV/$c$, $p_T^{\rmasso}<2$ GeV/$c$) in central heavy-ion collisions are significantly enhancedover that in p+p collisions while widths in azimuthal angle remain the same, inqualitative agreement with experimental data.
