Abstract

We report recent STAR results on medium modification of 2- and 3-particle correlations in heavy-ion collisions at RHIC. In particular properties of an additional extended correlation in pseudo-rapidity (``the ridge''), not present in p+p or d+Au collisions, are discussed. Next, the shape modification of the away-side correlation peak at low- and intermediate-p_T is investigated to look for signals of Mach cone shock waves or Čerenkov gluon emission.
