Abstract

In these proceedings we present the latest results from ALICE on direct photon and light neutral meson production in p-Pb and Pb-Pb collisions. The direct photon excess ratio R_γ in different charged particle multiplicity classes of p-Pb collisions at √s_\tinyNN=5.02 TeV is shown. In addition, we present the direct photon elliptic flow coefficient v₂ in central and semicentral events of Pb-Pb collisions at √s_\tinyNN=2.76 TeV. An outlook on ongoing and future measurements is given.
