Hard Probes in Pb-Pb Collisions at ATLAS

The heavy-ion program at the Large Hadron Collider has been commenced in November 2010 by three experiments including ATLAS, a multipurpose detector. That device was originally constructed to study high-energy proton-proton collisions but now it also proves to be an excellent tool for studying nuclear interactions. In these proceedings the measurements of hard probes from the lead-lead run at sqrt(s_NN) = 2.76 TeV based on a minimum bias data sample are reviewed. In particular, the results on jet quenching and W production are discussed. These measurements may bring new insight to the dynamics of heavy-ion collisions.
