We study the pion distributions in jets produced in heavy-ion collisions in association with trigger particles restricted to definite momentum ranges. We determine the centrality dependence of the associated particle distributions for both d + Au and Au + Au collisions in the recombination model. The central-to-peripheral ratios show significant dependence on centrality for Au + Au collisions but negligible dependence for d + Au collisions. The results are in agreement with the qualitative features of the data.
