Minijets are ubiquitous in heavy-ion collision experiments. However, they are often excluded
from the hydrodynamic simulations of QGP as they do not thermalize at short time scales
and are not treated as part of the collective medium. Using a concurrent jet+ hydro
framework, we show that the minijets could account for a significant portion of particle
multiplicity. Therefore, the energy deposition from minijet-medium interactions can
substantially modify the QGP transport properties inferred from model-to-data comparisons.
