Studying jet formation in the medium with the help of correlation and jet shape observables

The ALICE collaboration at CERN has dedicated a significant part of its physics program to study jet formation and modification in the hot and dense environment formed in heavy-ion collisions. These proceedings will summarize the latest insights we have gained about this process using data collected during Pb-Pb collisions at $\sqrt{sNN}$=2.76 TeV. In particular $\pi{^0}$- hadron correlations, jet mass measurements, and jet shapes of small-radius jets show a significant influence of the hot and dense medium on the measured jet fragmentation process.
