Measurements of jets and jet properties in $\sqrt{s_{NN}} = 2.76$ TeV   lead-lead collisions with the ATLAS detector at the LHC
  Jet quenching in the hot and dense medium created in ultra-relativistic heavy ion collisions is a well-established experimental phenomenon at RHIC. It has long been anticipated that the LHC heavy ion program would substantially advance the study of jet quenching by providing access to highly energetic jets and by measuring fully-reconstructed jets. Immediately following turn-on of the LHC with lead beams, in November 2010, that expectation was fulfilled through the observation of large di-jet asymmetries that may indicate substantial jet quenching. We will present recent results from ATLAS aimed to provide further understanding of this phenomenon. Measurements of single jet production and jet fragmentation in Pb+Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV will be presented.
