Abstract
The nuclear modification factor has been satisfactorily described by various jet quenching models. Nonetheless, all these formalisms, until very recently, underpredicted the high- (> 10 GeV) elliptic flow . We find that the simultaneous description of these observables requires to strongly suppress the quenching for the first fm after the collision. This shows the potential of jet quenching observables to constrain the dynamics of the initial stages of the evolution.
